Abstract: A volumetric, building unit including a support frame having a plurality of support frame members, a plurality of modular interior wall units, a plurality of modular interior ceiling units and a plurality of modular floor units and wherein the spaced apart coupling between the support frame and the interior walls and interior ceiling provides flexibility between the support frame and the interior wall and interior ceiling, so that the deformation of the support frame within a predetermined range is not transmitted to the interior wall and/or interior ceiling. Disclosed also a method for manufacturing a building unit and a modular building.

Abstract: A method for constructing a building on a water-body. The method includes piling a plurality of piles on a bed of the water-body for laying a foundation for the building. The method further includes marking a reference-mark on each of the plurality of piles at a predefined-distance from a surface of the water-body. The method also includes cutting each of the plurality of piles along the reference-mark. The method further comprises installing a first pile-cap, having a plurality of guiding elements extending therefrom, over a first set of piles of the plurality of piles. The method also comprises installing a second pile-cap over a second set of piles of the plurality of piles.
