Floating Houses - Dutch Architecture

As Holland is  1/3 below sea level, Dutch architects  have tried several ways to successfully keep water out of their country, the most successful way, is the use of  dikes, in which they maintain land, and pump water back out to the sea, however with climate change, sea levels are rising, and this method is not viable any more.

Therefore, the idea of building on top of water is a practical one, but with anything new, people are worried and anxious about what if's and how exactly does this work

This is where Water Studio, architecture firm, based in the Netherlands, claim to build safe housing built on  water, as many people are cautious and afraid of living on water.

There are no limits to design or materials, as I would have thought glass would be unsuitable to use, as it may smash when rising, but this is not the case, as a large amount of glass has been used within numerous designs, and in fact look like modular homes or like any other conventional, contemporary construct.

This is due to the hollow foundation in which enables the house to float, with reinforced polystyrene, encased in concrete, the underneath of a floating house, looks like an empty basement.

The theory behind this is that of a ship, the lower part of the ship is filled with air, therefore it is then able to support the weight above and still be capable to float.

the following video explains the key ideas in which makes this possible and why.
