The situation: there are 7 billion humans on the planet today. To get a equilibrium with nature having about 4 billion in land based cities is the planetary maximum. The 5 billion "rest" needs to solve their housing and other needs in the only space that is left and available - the oceans - within the next 3 decades. Sea level rise and coastal cities running out of development space will only accelerate this tendency.
This creates a need for a "marine construction business" of gargantuan scale...
Marine construction business. 5 billion humans will need real estate squaremeters at sea in the next 30 years as there is no development space left in land cities…
This means that the equivalent of 780.000 Empire state buildings needs to be built at sea. 26.000 Empire State Building per year…every year…in the next 30 years.
That makes more than 70 Empire State Buildings per DAY !!! to build on the ocean during the next 30 years just to keep up with the demand.
The Empire State Building holds 257.211 real estate square-meters on 102 floors and can host 6430 people in 40 squarmeter apartments.
Any architect and real estate investor who is not looking into large scale oceanic real estate development by now, will look like a Neanderthal in a few years.
Not convinced?... hear little talk about oceanic real estate?... Remember Internet ? nobody "saw it comming" nobody was "planning for it" - looks so obvious now ... - is dominating everything... we live in the 40 years where humanity is struck by wave after wave of groundbreaking technological change - faster than anybody can imagine it - ocean colonization is the next big thing to come.
One of the best ways to get started with ocean colonization is, to cook it down to a simple real estate deal. You produce 1 squaremeter of useable space at a cost of USD 166 (been there tested that) and you can sell that space at a price of at least 2000 USD. (check oceanfront real estate prices)
Any real estate agent can understand that business, any investor and any bank can understand it. It looks feasible and desireable business in any business plan.
This is why we should not go with "complicated turnkey concepts" but simply try to establish a fabrication site for "floating real estate squaremeters".
Creating oceanfront real estate by building sandbanks is a fairly common and well understood business that is going off on large scale in Dubai, Singapore, and other locations. It is a central paradigm of the real estate business that space can not be created but is limited - especially oceanfront space.
Concrete float solutions expand the sellable real estate to the water - this should be a desireable business field for investors that normally have no affinity to "boating" of any kind.
So to start with i would just sistematicly mass produce floating "empty building lots on the water" and offer them for sale. This is a simple deal, with a never ending pool of possible customers, easy handle for established real estate businesses.
The bay of cartagena for example is a hurricane free water space that is completly open for that kind of developments. A wide and empty protected waterspace surrounded by skyscrappers (some built by donald trump) - ready to do business.
My current development budget for floating installations in cartagena is limited to USD 5000/month. As you have seen on the pictures i can only crank out a few experimental squaremeters of floating real estate in small scale pilot projects in this finance frame.
But even so i already got requests for float out all kind of touristic and industrial installations. If i had a couple of floating platforms ready for sale at this moment i could sell them all...
It is of essence for the "guts understanding of the business" that buyers can step on their "empty building lot" and understand that this is not a kind of "boat" - this is solid real estate ground - ocean view.
Floating 5 star hotel in Gibraltar - read how cruiseships, marina development, hotel business, and floating real estate development are already merging to one business field. When coastal cities run out of space - floating real estate is the next big thing to come.
A floating permanent moored building (shaped as a cruiseship) in Gibraltar blending into a yacht marina ambient. We are living on a water planet, 99% of the living space available is in the water. With a population growth of 1 billion per decade the waterspace needs to be colonized. This is not a "fancy exception" it is a glimps of the "next big thing to come". Before mankind is ready to colonize space we need to get ready to colonize the oceans.
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.

Cost per squaremeter floating housing space
Models for protected Bays:
Floating housing in protected bays will come first, but it makes sense to build the units tough enough to be at least towed over open sea to be able to attend the "worldwide housing market" outside the protected home bay of the fabrication side...
To accomodate this demand of housing space, fabrication sites on the ocean need to be established that crank out housing space in a rate of a family houses per day – possible models…
Models for less protected waters that can stand a wave overwash or be placed below the surface to avoid wave movements:
Skyline Cartagena Colombia, one picture says it all, emerging tiger nation port cities running out of development space. The future of business, the future of freedom, who is NOT looking into ocean colonization right now, will look like a Neandertal in a few years.
4m sea level rise is predicted for Cartagena in the next decades...
