Unusual shape & planning.

The house, as recently constructed, measures 35.25 feet (10.74 meters) on each side. It has three main floors, with a terrace level above and a water storage tank at the apex, plus a large basement for office and storage space. The skin is glass framed with aluminum, which also serves to accentuate the shape.

Fitting a family residence into such a form was no easy feat. The architect took six months to convert the form into practical spaces and another three months to get the plans approved by local building authorities who had serious concerns about the unusual design's feasibility.

Ganapathy placed the circulation core at the center and made it the primary support structure. This stair core is triangular in plan and has reinforced concrete walls. The ground floor, the entrance lobby, is nothing but this core. Upper stories have larger floor areas. The relatively small ground floor also leaves room for another essential client requirement, on-site parking.

The differing perimeter shapes of the upper floors were determined by their level and the outer shell of the cube. The architect's original intention was that the floor slabs would cantilever from the central core, but this ultimately proved impractical. Seismic resistance required tie-beams from floor to floor at the perimeter to reduce deflection of the slabs at their farthest edges. The basement walls provided additional stability.

In Gurgaon, India, a fast-growing suburb of Delhi, an unusual house has just been erected. Designed by architect Ganesh Ganapathy, the building is a glass cube seemingly balanced on one vertex. Its uniqueness is admired by neighbors and passers-by, but working out the details of fitting a functional, stable house into such a form proved a formidable challenge.
