Designed as a picnic cottage, the House I at Mulshi perches on the hillside overlooking the lake below and is surrounded by a horse shoe of hills. Using local material the house straddles a fold in the land with a monsoon stream running below. A curved driveway was planned to wind through a fruit orchard.
The long house with a tilted lean-to roof faces the water view below and rises up to frame the hills behind and blends with its backdrop. Subsequently a kitchen and a garage wing were added with the same flying roofs behind the main house. The house has outer walls of basalt which wrap around inner verandah spaces; with lightweight steel roofs stretching across. Inside, the house has rubber-wood panels and ceilings, steel windows and a cool deep green floor. The living room initially designed to bridge the stream opens out to the lake views below and the hills beyond.
