A building over the water, maneuvering methods for the building and hosting sites of the building. The buildings including a superstructure (A) provided a floor structure (1) that is placed over a water surface (2) on which an inhabitable subassembly (3) is positioned, a support (B) sitting on ground (4) positioned under the floor structures (1), and mobile floating docks (C) with variable and controllable buoyancy that includes a load carrying platform (5) positioned under the floor structure (1). The superstructure (A) is held above the water surface (2) by the supports (B), that sit on the ground (4), and respectively carried by the floating docks (C), the superstructure being detachable from the ground (4), and transportable on water on the mobile floating docks (C), thus being possible to reposition the superstructure (A) on ground (4), at a destination of choice.
