A Kolkata home’s cavernous interior is dominated by curves

This Kolkata home is a contemporary experiment. How do the interiors of a home affect the psyche of its inhabitants? How can materials create moods to the extent that even sleep can be enhanced? These are questions with which interior designers and architects have long grappled, with each new project a further exploration of the nuances of the relationship between design and the occupants of the space. In this spacious apartment in one of the city's soigné neighbourhoods, a tall, double-height entry and disconnected rooms of varying heights, coupled with a client whose family business manufactures steel and TMT bars, provided its Mumbai-based architect Nitin Barchha of Studio Humus, and local interior designer Pooja Bihani of Spaces and Design the opportunity to craft an organic form that creates the illusion of weightlessness whilst harmonising the disparate spaces.

Desinging Cavernous, a modern Kolkata home

‘The clients wanted something unconventional and that shows the possibility of materials like cement and TMT bars, which are usually used to reinforce concrete,’ says Barchha. 

Given the hard materials used – TMT bars, Ferrocement, microcrete, composite stone and Burmese teak – what’s striking about the apartment is how light the spaces are. This is largely because there are few straight lines to be found, Barchha and Bihani moulding curved shelves and desks out of sloping walls, winding arches over rooms, and dripping droplets of volumes from ceilings to divide rooms or create alcoves. 

For both designers, the staircase – a freestanding helical shape that anchors the 22ft ceiling with a small conch-shaped bathroom tucked into its base – is the apartment’s tentpole feature. The dominance of curves is deliberate.

‘When we enter a curvilinear space, our subconscious associates it with the safety of the caves in which our ancestors lived,’ Barchha proposes, adding that the form also promotes deep sleep as it puts the cerebral cortex to rest from its perpetual state of alertness during the day.

The result has intriguing elements of Zaha Hadid alongside the echoes of yposkafa (the white cave houses of Santorini, Greece), the Fred Flintstone residence, and Luke Skywalker’s homestead on Tatooine. 

That the sinuous forms never descend into parody is due to the designers being clear of their intentions from the outset. ‘The whole idea of coming home was important,’ Barchha says. ‘Because of the high ceilings, we didn’t want it to be like an aerial, out-of-scale space.’

Bihani adds that the design and construction teams spent many hours on site harmonising the different ceiling heights from passages into rooms. 

‘Given the physical restrictions of the apartment, it was really difficult to integrate the angles and curves into a seamless form.’
