When it comes to create housing space and real estate on the Ocean the colonization technology of choice is definitly concrete shells...
Things like the Ramform harbor or floating concrete honeycomb structures come to mind.
Definitly the next step to ocean colonization will just be ONE step away from what is already floating on the oceans today.
To get an overview what are the structures that pave the way to ocean colonization check "Outstanding floating concrete Structures"
