The construction site lies in a small triangle between a motorway and a main road in the southern periphery of Luxemburg.

Although the H2O structure has been given the discrete ornamentation of a grid-like structure, from the outside it appears as a compact but elegant four-storey unit. The interior structure consists of three overlapping, slightly asymmetrical units all accessed through a central entrance. The structural design follows that of blocks with interior courtyards.
The double façade serves as a noise barrier with an inner thermal layer in which single windows can be opened and the second, slightly inclined layer of glass which provides efficient protection from external noise.
