Taking Cues from the Regional Vernacular to Reimagine Contemporary Living.
The Cantilever House draws from the regional vernacular and finds expression through a contemporary lens to become a home for a family of four. Located in the Raj Nagar locality of Ghaziabad, part of the National Capital Region of Delhi, the house is designed in response to the clients' love for the outdoors. It employs a series of mechanisms that minimize resource consumption, and reduce the building's environmental impact while enhancing the residents' thermal comfort.
The large cantilevers that the house derives its name from, anchor its design vocabulary, highlighting the scale of the building and breaking its mass through the focus on horizontality. The primary challenge was to design the frame with judicious use of steel for economic viability, given that the cantilevers form a dominant part of the design scheme and a typical one demands adequate steel reinforcement to generate structural integrity. Additionally, the design received scepticism from the client, and workers on the site had to be trained to execute the construction with precision. The overarching design intent however, was to create a sense of privacy while channelling an open, connected environment for the family. This took shape through an interesting interplay of living spaces, with the main living areas occupying the ground floor and the private areas located on the first floor.
The design scheme was largely driven by two endeavours: first, to assimilate traditional building wisdom and find an appropriate expression within the contemporary context. Second, the distribution of various private spaces and varying volumes are planned in order to account for the diversity of usage based on the time of the day and privacy required. a series of connected living spaces, courtyards, and bedrooms were plannedwith the intent to create a home that could be brought to life throughout the day. Similarly, the cantilever slabs spanning the verandah, render a modern aesthetic while creating shaded spaces underneath.
The geometry of the cantilevered forms is such that it aids in externalizing rooms and maximizing space, serving not only aesthetic but also functional purposes. Spaces are fluid and interwoven, with interstitial spaces creating seamless transitions from the inside to the outside. As one is led into the house through the double-height lobby on the east-facing entrance porch, they are pleasantly surprised by the garden's view with a water body. Bringing the exterior environment inside, by providing green areas in the interior spaces, establishes a strong visual connection with the outdoor landscape.
The east (front) elevation of the house features expansive projections that break the mass of the house. The master bedroom, located on the first floor is designed as a cantilevered block, jutting out over the landscaped garden. A large opening brings in ample light whilst offering expansive views of the front lawns.
The design lays emphasis on responsible living through its layout, the use of passive cooling techniques and by drawing energy from renewable resources. Metaphorically, the house is an oxymoron, serene and cool, with minimalistic decors, yet simultaneously, adventurous in its design approach.
The house responds to the hot and dry climate prevalent in the region through a host of design interventions and passive cooling techniques. By placing the living areas in the north and the east to bring in sufficient daylight and by allocating space for private areas in the west and the south, the house records minimal heat gain throughout the day. The windows on the south are shaded by a pergola to ensure that the south face remains comfortable throughout the year.
The interiors comprise a material palette featuring varying shades of browns and greys juxtaposed with the use of bright, upholstered furniture and decor elements. The house is full of cozy nooks, designed for maximum comfort and wellbeing, as well as encouraging responsible living.
