Orsos island a nice vision of an artist how a floating family sized property can look like - i would prefer a bow with no boat hanging under it (smashed to pices in waves - not thought through) - to deal with waves the shape would probably be better adressed with a ramform.

What matters in the end is that we go away from "yacht building materials and squaremeter costs" and come to concrete shell and honeycomb hull building techniques that allow to lower the cost to a housebuilding cost level, with squaremeter prices matching european and US average housing cost prices.

A floating concrete dock from Japan that drifted over the pacific after being broken lose by the tsunami and was finally washed ashore in Oregon gives a good impression how the underwater part of a concrete float looks after being in the water for a long time without going trough a intense maintenance shedule as ships normally do.

It is clear that a floating steel dock would have rusted trough and sunk halfway if doing a similar journey.

Also worth to mention that a concrete dock can not only survive the tsunami but stay intact to survive a long journey over the pacific.

Japanese dock torn off in tsunami floats to beach in Oregon

The 165 ton concrete and metal structure, which is the biggest piece of flotsam to make landfall on the US west coast so far, floated on to Agate beach 100 miles southwest of Portland. It was fitted with a plaque showing it is one of four similar floating docks that broke loose from the port of Misawa when the disaster struck on March 11, 2011. (washed ashore june 2012).

Owner: Washington State Department of Transportation
Contract Amount: $4,434,937
Location: Orcas Island, WA
Project Duration: 05/2008-11/2008

This project involved replacing two timber floating dolphins at the Orcas Island Ferry Terminal with two new concrete floating dolphins. Each concrete dolphin is 80’ long by 40’ wide and 14’ deep and is portioned into 21 interior cells. The dolphins were cast on Manson barges at Manson’s Seattle facility on the Duwamish River. Additional work included the replacement of the six anchors holding the existing timber dolphins with eight new concrete anchors.

The Seascraper

Illustration by William Erwin and Dan Fletcher, eVolo

Touted as an eco-friendly floating city, the Seascraper (pictured in an artist's conception) is among a raft of concepts for sustainable offshore settlements. With more than seven billion people on the planet, mass migrations to cities, and increased risks of flooding and sea level rise, more and more architects and innovators seem to be weighing anchor.

(Related: "Sea Levels Rising Fast on U.S. East Coast.'")

The Seascraper—a self-sufficient community of homes, offices, and recreational space—was designed with the intention of slowing urban sprawl, according to its designers.

The vessel's energy independence would come from underwater turbines powered by deep-sea currents as well as from a photovoltaic skin that could collect solar energy. The concave hull would collect rainwater and allow daylight to reach lower levels. Fresh water would come from treated and recycled rainwater via an onboard desalination plant.

This green machine would also help keep marine populations afloat, so to speak, with a buoyant base that serves as a reef and discharges fish food in the form of nutrients pumped from the deep sea, the U.S. design team says.

The project is anchored by an artificial oval island, where sculpted resort towers connect to an underwater hall that provides fascinating views of the sea world. Jetties feed 80 floating houses called “Jelly-fish”, which feature an underwater viewing room in the belly. Guests move about in electric vehicles or on the water in yachts that burn clean hydrogen, and a series of underwater halls give visitors an intimate experience of the sea from below.

The design is made to celebrate the natural world, but as fill projects have a history of financial and environmental problems, we are a bit dubious of the concept.

Many of the world’s greatest cities now sit on land that was artificially created– think of a swampy New York, San Francisco’s downtown in the bay, and large swaths of Hong Kong’s coast. And as technology evolved so did the resolve to build bigger – but not always better. The famous Kansai Airport in Japan is the largest artificial island, and relives congested cities of air and noise pollution, but the island has been sinking at a much greater rate than estimated and the project is a financial boondoggle. Dubai took it even further by attempting to build entire communities out of energy intensive artificial islands, only to see the scheme sink back into the ocean.

As the world’s oceans are rising faster than predicted, the most unlikely place to pitch tent would seem to be a few feet above sea leavel on sinking land.

Inspecting Floating Homes

by Nick Gromicko and Kenton Shepard

http://www.nachi.org/inspecting-floating-homes.htm

There are some types of homes that don’t fit neatly into any category. They’re unusual, and that’s what attracts many people to them. Floating homes are one of these types.

Each state defines floating homes differently, but in general, they’re:

  • constructed on a float;
  • designed and built to be used as a residential dwelling;
  • stationary by being moored or anchored, and not meant for navigation;
  • without a means of self-propulsion;
  • powered by utilities connected to the shore; and
  • permanently and continuously connected to a sewage system on shore.

The definition of a floating home varies according to the jurisdiction where a home is located, which is important because jurisdictions often have regulations with which such homes must comply. Regulations are also different for similar structures, such as house barges and houseboats.

House Barges

House barges are vessels that are designed to be navigable; that is, they’re meant to move around, but not under their own power. They’re meant to house people, but they’re also meant to be towed. If they become permanently moored or anchored, they may have to comply with regulations that govern floating homes. House barges are fairly rare and many jurisdictions do not allow new ones.

Houseboats

Houseboats must have a seaworthy hull design that meets U.S. Coast Guard standards for flotation, safety equipment, fuel, electrical power, ventilation, and an on-board sewage system. They’re capable of being used for water transportation, and if they’re used for residential purposes, they have to be able to travel under their own power and must have a method for steering and propulsion, as well as deck fittings, navigational and nautical equipment, and the required marine hardware. Without these features, they’re categorized as house barges.

Floating Homes

Floating homes are generally required to be moored in areas designated for that purpose, and in many areas, the growth of such “floating communities” is discouraged by local jurisdictions. Cities and towns tend to view them as cluttering the waterways and they present unique problems requiring special efforts, which puts pressure on limited city budgets.

Where they’re allowed, they’re usually moored alongside docks with projections called slips. To moor a floating home is to attach it to a dock or permanent anchor with ropes instead of a rigid connection. This allows the home to rise and fall with the tide or seasonal changes in water levels and puts less stress on permanent docks and mooring anchors.

Although some floating home communities allow slips to be sold, the slip facility or marina is typically owned by a company that rents the slips out. In most places, homes are subject to property tax, which helps defray the cost of police and fire department services. In some states, such as Oregon, homes are taxed as personal property, so no tax is paid on the land. Slip rental prices are usually figured by the linear foot. A management company maintains the slip facilities for which there is usually an additional monthly fee. The marina may be responsible for providing some utilities, such as potable water, natural gas, electrical power, and/or sewage. In some areas, the homeowner must contract directly with the utility provider. Gas, water and sewer pipes and electrical power lines are suspended from the undersides of docks and branch out to homes in each slip.

Sewage handling is worth mentioning. Each home has what’s called a “honey pot,” properly called a macerator. This is a tank in the 30- to 50-gallon range with a mechanism that grinds sewage down to about 1/16-inch, with a pump that pumps it ashore through a flexible hose. Inexpensive honey pots may last only a couple of years, and replacing them is an expensive and unpleasant chore. Stainless steel is a good choice for tank material.

Sewer pipes in modern systems are connected to the public sewer system. Smaller marinas sometimes have a main holding tank that may be connected to the public sewer system, or it may require pumping.


In northern communities, such as Portland and Seattle, frozen water pipes can be a problem, so pipes above the waterline should be insulated. A similar problem can happen in homes with high-efficiency furnaces. Condensate drainage pipes usually discharge out the side of the home into the water. In cold climates, the pipe can freeze over and condensate will start to discharge into the part of the home where the furnace is located, which can be a mess. It can be a smelly mess if condensate winds up in the bilge and items start to decay.

In most floating home communities, the dock facilities are usually in good condition,.

Most floating home communities do not allow conditions such as those depicted above because they want to maintain property values.  Also, homes in most communities are subject to inspection and the enforcement of jurisdictional and marina regulations. Homes like those depicted in Figure 1, located in Sausalito, California, sell for well over $1 million.
 

Floats

Obviously, floating homes are built on flotation devices, and there are a number of different types. Modern home flotation devices are usually concrete barges, logs, foam, or foam-filled steel. Steel pontoon floats are sometimes filled with foam.  A few older homes may still rest on hollow plywood floats that have been coated with fiberglass. These can suffer from decay caused by fresh water intrusion from above. Any plywood floats you see are likely to be old and can be dangerous. While log floats and concrete barges fail slowly, plywood floats may fail catastrophically, causing the home to suddenly sink.


Concrete barges are able to float because of the large amount of water they displace. They’ve been around since about the 1940s. If concrete of the proper strength is used (approximately 4,000 PSI), barges may fail mainly through corrosion of the steel reinforcement bar (rebar). Construction of modern barges includes a grid of #4 (1/2-inch) rebar in the walls and bottom, and additional  #5 and #6 rebar at key locations, such as in the bottom and corners and along the top of the wall. Until around the late 1990s, rebar was installed uncoated, which limited the service life of concrete barges to about 40 years.  Rebar is now coated with epoxy, which extends the expected service life considerably. Fusion-bonded epoxy, which is applied in powder form and turns molten at between about 350° to 480° F, can be applied to rebar, creating a barge that can last hundreds of years. As of 2011, prices for new concrete barges were around $71 per square foot.  Some concrete hulls have been constructed using weaker mix designs that  are more appropriate for land-based foundations. These barges can deteriorate more quickly than those built using a proper mix.

Barge exteriors are painted with polyurethane epoxy. Over time, this epoxy coating will be deteriorated by weather, slowly exposing more of the concrete, as you see in the photo below.

Figure 13:  It’s not necessary to clean the bottom,
and doing so may damage the epoxy coating.

In older barges, this means that any steel close to the surface may be exposed to the corrosive effects of salt water because concrete is porous. Any cracks that develop can also expose rebar to salt water, so, when examining the barge, cracks that show rust are a bad sign. Repair involves cleaning out the crack and filling it with an appropriate material.


Figure 14:  A crack showing rust means that rebar is corroding.
An inspector should recommend repair.

Figure 15:  This photo shows a diagonal crack with no rust. No rust means no corrosion,
so there is no need for repair unless the crack grows and begins to rust.

Cracks can develop several different ways. As with most concrete structures, concrete barges will have shrinkage cracks, but these are surface cracks that appear not long after the barge material is first poured and will be filled when the epoxy coating is applied to the hull exterior. Shrinkage cracks are not a concern because they are a function of the natural curing process.

In some areas, floating homes will rest on the bottom at low tide. This can create stresses that can contribute to cracking. In areas where homes rest on the bottom at low tide, the bottom quickly conforms to the shape of the boat. The exception is when an object of some type is buried in the mud or sand beneath the barge. This object might be part of an old boat, or part of an old dock, such as a piling. This situation can create point loads that can damage the hull.

Positive Flotation

Some concrete hulls are constructed with a large cavity in the bottom filled with expanded polystyrene foam.  This gives the hull positive flotation, so even if a breach of the hull were to develop, unlike a concrete barge, the hull with foam will not sink. After being placed in the cavity, the foam is covered over with a cementicious material.

For financing and insurance reasons, the difference between a concrete hull with or without positive flotation can be important, so when inspecting or buying a floating home with a concrete hull, be sure to look at the documentation to find out whether concrete barge construction includes positive flotation.

Figure 16:  A concrete barge with positive flotation

Another way to recognize hulls with positive flotation is that a concrete barge has a bilge. The bilge is the space beneath the floor framing of the home. Some jurisdictions may require a hull without positive flotation to have a bilge pump, which is very similar to a float-activated sump pump. In a positive flotation concrete float, the space beneath the floor is also filled with foam.

Figure 17

Entering the space beneath the floor can be difficult or impossible without taking invasive measures. In the photo below, the access hatch is located beneath the upper stair landing at the left.

 
 Figure 18
 

Livable spaces in floating homes may be created in one of two ways. A home may be built on the float or barge, or an existing boat may be mounted on either one.

Figure 19:  A home built directly on a concrete barge

Figure 20:  A home built by mounting a boat on a concrete barge

Figure 21:  Here you can see the shoring supporting the boat
 until the deck is framed in around it.

Boats are loaded onto barges by sinking the barge in deeper water, floating the boat over the barge, and then raising the barge beneath the boat.

Figure 22:  Decking being constructed around a boat hull resting on a concrete barge

Figure 23:  Sometimes, custom barges are built to the shape of the boat hull.

Expanded Polystyrene Billets

Homes may rest on rectangular chunks of closed-cell expanded polystyrene (EPS) foam, which will not absorb water. Since the 1990s, the U.S. Army Corps of Engineers requires that all foam used in marine (salt water) environments be encapsulated.  It’s more common for EPS foam to be used for adjusting the trim of floating homes than as the primary flotation method.

Log Floats

You may also see logs used as floats. This is traditional in the Pacific Northwest because of the timber industry located there. The photo below shows logs being moved into place for a houseboat that is being converted into a floating home. According to the photographer, the cost of these logs was about $1,000 each.

Figure 24
(Courtesy of Scott Niesen)

Homes rest on stringers that, in turn, rest on the log floats. Logs are typically notched to accept the stringers. Ripping logs, such as those you see in the photo below, provide a flat surface on which the stringers can rest, which makes stringer placement easier and makes the logs essentially self-leveling.

Because there are no standards for the inspection of floats, items inspected and commented on in reports may vary.

Here are items commonly inspected during the float inspection of a log float home:

  • mooring connections:  Some jurisdictions have minimum requirements for chains and chain plates. Mooring connections that are too loose may allow the float or home to rub and wear against the dock or slip.
  • logs:  Describe the approximate diameter of the logs, their quantity, and mention any splices. Describe the degree to which decay has taken place. One of the requirements for decay to take place is the presence of oxygen. Since water contains little oxygen, the underwater portions of logs deteriorate much more slowly than the portions above water. Since end-grain absorbs water more easily, some decay may take place there also. Logs may last up to 75 years. Logs for floats are sometimes reclaimed from older homes and installed in newer homes, so logs should be checked for uniformity of condition.
  • flotation:  If additional flotation has been added, the adequacy of its condition and location should be commented upon. Because trim flotation often has to be added due to changing weight distribution when a new occupant moves their belongings aboard, commenting on the space available for additional flotation is a good idea. Also mention whether adding flotation will increase the draft. The draft is the depth of the float structure beneath the waterline. Contractors specializing in adjusting trim with flotation can usually make changes in less than an hour.
  • stringers:  Describe the material of which the strings are made and their nominal size. If they’re wood, find out if it’s pressure-treated wood. If they’re steel, find out if they have an adequate protective coating.
  • floor structure:  What is the nominal size and spacing of the floor joists?  Are they structurally adequate?  Was pressure-treated wood used?  Was pressure-treated wood/plywood used for the sub-floor?  Is the floor insulated?
  • deck condition:  For recreation and for access to the home exterior, many homes have exterior decks that project out from one or more sides of the home. The deck’s structural support, framing and planking should be inspected for corrosion and decay.

Figure 27.2:  Floatation for decks and docks may be different from that of
floating homes.

Potential Requirements and Limitations

When inspecting floating homes, inspectors and consumers should be aware of the local jurisdiction’s requirements and limitations for the following.

Jurisdictions

  • minimum freeboard:  “Freeboard” is the distance between the waterline and the lowest portion of the house. The minimum varies with jurisdiction and is often somewhere between 12 and 16 inches.
  • maximum list:  To list is to tilt. A floating home should sit parallel to the waterline. If a home is constructed or is loaded with the occupant’s belongings in such a way that the weight is unevenly distributed, the home may list. The maximum list allowable can vary with location but may be in the neighborhood of 6 degrees, or 2 inches overall. In some circumstances, foam flotation can be placed beneath the home to correct a list.
  • Check any local height limitations.
  • Check whether there’s a limit on the number of dwellings that can use a single float or barge.
  • Some jurisdictions may require that the float be durable to the satisfaction of a marine surveyor or professional engineer, meaning that it may not be not subject to deterioration by water, mechanical damage due to floating debris, electrolytic action, water-borne solvents, organic infestation, or physical abuse, Jurisdictions, lenders and/or insurance companies may require inspection of the float, including the underwater portion, at specified time intervals. Inspection may need to be performed by a diver qualified to inspect floats, or by a marine surveyor.
  • Jurisdictions and marinas may have setback or other requirements that limit additional construction on or expansion of an existing floating home.

Marinas

  • Marinas may have limitations on the number of non-family members who can share a floating home.
  • Slips may be difficult to find. If for some reason a homeowner loses a slip, it may be difficult to find a marina in the desired area that has room for another boat.
Moorings
  • Floating homes in communities located on rivers may rise and fall as much as 25 feet as seasonal water levels change. At extremely low water levels, such as might occur during drought years, homes with too deep a draft due to added flotation may go aground. Boats with log floats are generally not designed to rest on the bottom, and the torque created by unintended contact with the bottom can cause damage. When this happens, as soon as increasing water levels make it possible, areas of the river bottom where the floats have made contact will be excavated, or flotation will be removed.
  • Floating homes move. Homes may be moved by strong winds that blow them across the water until they reach the end of the mooring lines, which stop them with a jerk. Wakes from passing boats can also move homes. This can be a concern if someone is on a ladder or can throw small children aboard off balance.
  • Gangways or ramps serve as means of egress and should have a non-skid surface or cleats. They may also have to meet minimum width or maximum slope regulations.

Inspection

Inspecting the house portion of a floating home is not much different from inspecting a home ashore, but without special expertise, home inspectors may not be qualified to inspect log floats, barges or other flotation devices. In most places with floating home communities, there may be no standards for flotation device inspection. Finding people qualified to inspect floating homes can be difficult. Marine surveyors often give the float only a cursory examination that doesn’t include the underwater portion, and they usually know very little about inspecting homes. Divers hired to inspect the underwater portions of the floats also know very little about inspecting homes. Home inspectors typically have expertise in inspecting the home, but know very little about how to inspect floats. Dive or survey fees may be over $500. If the prospective buyer also has to hire a home inspector, inspection fees alone can sometimes run as high as $1,000. The most logical method of inspection is to have a diver perform a flotation inspection or dive survey, and to have a home inspector inspect the house.
 

Utilities

 
  • Electrical installations installed near the water may need to meet special requirements for wet environments.
  • Overhead service drops may have to meet height minimums from walkable surfaces beneath.
  • Water service connections may require back-flow preventers and flexible connections.
  • Are any water distribution pipes above the waterline insulated?

Mortgages and Insurance

The ease of finding a lender for a floating home varies with the area. Established communities usually have at least one lender, although rates may be a little higher, and they often want 20% to 25% down. Seller financing is sometimes available. The availability of insurance also varies with location and may be expensive. Both a mortgage and insurance may be easier to find if the home is located in a jurisdiction that has standards with which floating homes must comply.

Figure 28:  A contrast in quality

The home in the photo above rests on expanded polystyrene floats, some of which are encapsulated and some of which are not. The front doorstep leaves something to be desired.

The covered entry of the home in the photo below is attached to the home and will rise and fall with the tide. This home is located in an area where the floats rest on the bottom at low tide, so a minimum headroom clearance could be calculated.

Figure 29

Figure 30:  Wood in a marine environment

In the photo above, the widespread discoloration on the wood shingle exterior is biological growth. This growth holds moisture against the wood and will accelerate decay.
 
Depending on the location, InterNACHI home inspectors who wish to expand their services and expertise should be prepared to encounter many types of housing, especially as homeowners seek innovative, green and/or inexpensive ways to enjoy full-time what the local geography has to offer, including lakes and waterways.

Concrete has clearly emerged as the most economical and durable material for the building of the vast majority of marine structures. Reinforced concrete too has overcome the technological problems making it a suitable material for the construction of advanced marine structures such as offshore drilling platforms, superspan bridges and undersea tunnels. As the world becomes increasingly ocean-oriented for energy and other resources it is predicted that construction activities during the 21st century will be dominated by concrete sea structures. The performance of concrete in the marine environment is presented here in a logical manner giving state-of-the-art reviews of the nature of the marine environment, the composition and properties of concrete, history of concrete performance in seawater, major causes of deterioration of concrete in the marine environment, selection of materials and mix proportioning for durable concrete, recommended concrete practice and repair of deteriorated marine structures. It is of value to any design or construction engineer responsible for marine structures.

The Netherlands - Dura Vermeer

Picture

Dura Vermeer designed and constructed 37 homes in Maasbommel in The Netherlands near the Maas River dyke, a river which is known for its seasonal flooding. Around two-thirds of The Netherlands' land mass lies beneath sea level, meaning the threat of rising water heights poses a significant threat to the livelihoods of many Dutch citizens. "The columns have been driven deep into solid ground," explained Dick van Gooswilligen, a Dura Vermeer architect. "They are even strong enough to withstand currents you would find on the open sea" [8]. The Maasbommel community has become an iconic example of the trend towards amphibious housing in coastal areas.

Featuring a design similar to the Dutch homes by Dura Vermeer, these homes were pushed for by Lousiana State University professor Elizabeth English, who is the founder of The Buoyant Foundation Project. These homes could protect many homes from the disastrous flooding associated with Hurricane Katrina [17].

Floating Stadium Platform Singapore

The Float at Marina Bay, also known as Marina Bay Floating Platform (Chinese), is the world’s largest floating stage. It is located on the waters of the Marina Reservoir, in Marina Bay, Singapore.
Made entirely of steel, the floating platform on Marina Bay measures 120 metres long and 83 metres wide, which is 5% larger than the soccer field at the National Stadium. The platform can bear up to 1,070 tonnes, equivalent to the total weight of 9,000 people, 200 tonnes of stage props and three 30-tonne military vehicles. The gallery at the stadium has a seating capacity of 30,000 people.

The pontoons represent versatile marine infrastructure that can be implemented in a broad range of applications including:

Breakwaters – The pontoons:

  • wavesProvide very substantial wave attenuation
  • Are especially well suited for deep water breakwater locations
  • Rise and fall with the tide
  • Create flushing bays

Piers – The pontoons:

  • Can provide berthing for vessels of up to 400 feet in length
  • Can accommodate pedestrians and vehicles

naniamo

Floating Platforms – The pontoons:

Can carry significant loads such as

  • Heavy equipment and
  • Building

The pontoons may be:

  • Resurfaced to a high level of finish such as stamped concrete
  • Ballasted to achieve the desired freeboard and draft
  • Structurally enhanced, as required, to carry additional deck loads
  • Secured by anchors and/or piles

In a move that decisively overturns the limitations of land-scarce Singapore, JTC is embarking on developmental work for the Very Large Floating Structure (VLFS), which will function as an oil storage facility of the future. The VLFS is designed as a collection of large fl oating platforms which can either be moored to land or operated as standalone units. Made of concrete, the VLFS will offer storage solutions for oil and petrochemical products. A VLFS with a storage capacity of 300,000 cubic metres occupies no more than 5 hectares of foreshore space, compared to 20 hectares of land required by a comparable conventional facility. With global energy demand expected to grow by 50 per cent in the next two decades, the VLFS strategically positions Singapore to entrench itself as a global chemical hub by offering innovative storage options. When the first VLFS is ready, Singapore will take its place as the first country in the world to have developed a floating oil storage platform made from concrete.

Space on dry flat land for building purposes, particularly in urban areas, is slowly diminishing. In such situations, concepts like this floating house in the middle of a lake in Nevada kick in pretty well. Afloat in the Lake Mohave Marina, this 2,000-sqaure-foot building has grabbed a load of attention from those who stumbled across it. Built from stuff that might have probably ended up in dumping yards, this floating structure is a marvel of recycling, using rice hulls, Styrofoam, and recycled tires. The building will play home to the office of the houseboat rental firm, Forever Resorts, and was designed by Ken Couverley, who took two years to get the design of this one straight.

Floating platform

Floating terrace designs are based on Marinetek's plastic or concrete floats. Frames are constructed in either hot dipped galvanised steel or pressure impregnated pine and decked in wood plastic composite or Nordic pine. Floating terraces have a high load bearing capacity to accommodate high dead load and live load requirements. Floating terraces are always customised and built to meet even the highest standards and specifications for public installations.

Designed by the USA-based ParrLuxe  company, the cabana is intended as a solution to the problem of guests on large charter yachts having to walk up several levels to sunbathe, and then down the same levels to access a swim platform for a dip in the sea.



With room for 15 to 20 people, the cabana inflates in 15 minutes from a small air compressor,
and comes complete with wraparound seating, a stainless steel swim ladder with teak steps,
and a rigid carbon-fiber canopy frame.

ParrLuxe also offers a cabana with a natural swimming-pool option - a net-covered hole in the floor of the cabana lets in sea water, while keeping out pesky sea creatures and jellyfish.


As our reader Dave pointed out, the cabana can also be tethered behind a boat, making it
ideal for children to use.

The "Sea Cabana" is available in black, white, and turquoise, and is priced at $35,000.

Valencia Opera House
(Palau de les Artes Reina Sofia)

Valencia, Spain

The opera house in Valencia Spain, designed by Santiago Calatrava, this element was completed in 2006 and is the final element of the 2.6 hectare City of Arts and Sciences. The sculptural structure, wrapped by open-air terraces and enveloped in two symmetrical, curving concrete shells, houses 3 auditoriums at its core.

A fourth auditorium and music school are housed near the base of a massive steel leaf that leaps to the top of the main building to create the canopy. Under the huge curved roof structure, 230 metres in length, the building rises 14 stories plus 3 stories below ground. Its height is 75 metres, with 40,000 sq. metre of auditiorium and accommodations space.

Floating homes of the future


Life at sea — it sounds far away, like a distant lifestyle reserved for Navy seamen, ocean trawlers and submarine captains. But as shorelines recede, populations grow and property-ownership ideas evolve, designers and architects are prompted to re-think how — and where — we live. Many look to the water.

Shaped like domes and flowers, few of these notions of futuristic dwellings will ever go beyond the design stage. However, this doesn’t mean homes that float, submerge or drift on rivers are the stuff of sci-fi.



“Just because a design vision is not built yet, does not limit its potential impact,” says Maria Lorena Lehman, Founder of Sensing Architecture, an online forum for architectural design, science and new technologies. “In fact, by proposing new ways of living, including on the water, architectural design is advanced, and in turn, human life is improved.”

Here are five examples of how people might be living on the water someday:

Pearl

This open-sea eco houseboat is the brainchild of industrial designer Orhan Cileli. Most houseboats have flat bottoms so they rock heavily if they hit big waves. Pearl's design would be stable and efficient out at sea. In fact, the houseboat was actually inspired by a fishing bobber.

There's more to the Pearl than cool-looking design, though. The four-story house, which has a deck and greenhouse, would make use of alternative energy technologies, including wave and solar energy, to move it around and provide electricity.

WHY Floating Home

With more than 3,000 square feet of living surface and three levels of decking, the WHY concept yacht is designed for living — and entertaining. In part, what distinguishes the design is its emphasis on sustainability (relative to other yachts.) The vessel relies on thermal energy and recycled organic and inorganic waste, ideally resulting in a low impact on the sea. Luxurious and easy on the eye, the minimalist interiors features walls of glass, modern furnishings, an elaborate curved staircase and a tree growing in the center of the living space.

Fioriella

Hyun Seok-Kim designed this quaint floating retreat. Closed, it looks like an egg. Open, its petal-like panels resemble a lotus flower. The interior of Fioriella includes a convertible sofa-bed for day/night relaxing. There's a deck at water level so residents can lounge and view passing scenery. Best of all, the cabin is designed to provide underwater panoramic views. A jet engine and eight nozzles keep the pretty vessel afloat.

House On Water

Designed by Jedrzej Lewandowski of Le 2 Workshop, this floating house features a lower deck and elevated main house. And while it may look completely futuristic, the floating home actually exists. The vessel was conceived as a vacation rental.

The idea was to allow folks on holiday to have the experience of a yacht without navigation or a bumpy ride. Solar panels on the top of the house are among its eco features. It also includes systems to remove salt from the water and has SMART controls allowing for adjustments via a computer.

The Citadel

This floating apartment complex was designed by Koen Olthuis of the Netherlands. Thanks to the use of water-cooling techniques, the multi-family residence will reduce energy consumption by about 25%.

The design is a response to the the ever-encroaching waters in the Netherlands. Rather than fight this in traditional ways, such as with dykes, Olthuis is embracing the environmental changes and designing to adapt, instead. The apartment building will be built on top of a floating concrete caisson foundation and will include 60 luxury apartments, a parkade, and a floating road to get there. Each unit will have its own garden terrace and of course, water view.

JJ, in fact we have asked ourselfs the same question. It burns down on price per squaremeter living space.

At the moment my best educated guess (supported by small scale pilot projects) for a living space that stays maintenance free afloat for some 200 years (means ist has "real estate quality") is: some USD 166 per squaremeter in a project geard for "cheap living space".

If you compare this to the cost of landfill in Singapore or the Netherlands or Dubai that is currently ranging around 800 USD / squaremeter (just the sandbank/landfill squaremeter no "housing space" constructed on it yet) - floating living space is quite competitive on the "living space real estate market" as it is at this very moment.
