Kanchanjunga, an 84m high rise of of 32 luxury apartments, is a series of vertical bungalows. Designed by architect Charles Correa in the 70s, the building's successful application of climatic sensibilities make it stand out among the other built forms of the skyline.
The Kanchanjunga Apartments are a direct response to the present culture, the escalating urbanization, and the climatic conditions for the region. They pay homage to the vernacular architecture that once stood on the site before the development in a number of ways. More on Kanchanjunga Apartments after the break. In Mumbai, a building has to be oriented east-west to catch prevailing sea breezes and to open up the best views of the city. Unfortunately, these are also the directions of the hot sun and the heavy monsoon rains. The old bungalows solved these problems by wrapping a protective layer of verandas around the main living areas, thus providing the occupants with two lines of defense against the elements.
Correa pushed his capacity for ingenious cellular planning to the limit, as is evident from the interlock of four different apartment typologies varying from 3 to 6 bedrooms each. Smaller displacements of the level were critical in this work in that they differentiated between the external earth filled terraces and the internal elevated living volumes. These subtle shifts enable Correa to effectively shield these high rise units from the effects of both the sun and monsoon rains. This was largely achieved by providing the tower with relatively deep, garden verandas, suspended in the air.
Clearly, such an arrangement had its precedent in the cross-over units of Le Corbusier's Unite d' Habitation built in Marseilles in 1952, although here in Mumbai the sectional provision was achieved without resorting to the extreme of differentiating between up-and-down going units.
The building is a 32 story reinforced concrete structure with 6.3m cantilevered open terraces. The central core is composed of lifts and provides the main structural element for resisting lateral loads. The central core was constructed ahead of the main structure by slip method of construction. This technique was used for the first time in India for a multistory building.
The concrete construction and large areas of white panels bear a strong resemblance to modern apartment buildings in the West, perhaps due to Correa's western education. However, the garden terraces of the Kanchanjunga Apartments are actually a modern interpretation of a feature of the traditional Indian bungalow: the veranda.
