Two flats in a Mumbai high-rise were combined to create a "minimal but playful" home for three generations, which local studio The Act of Quad has decorated with multiple spherical and rounded shapes.

Located in the city's Ghatkopar suburb, the four-bedroom, 325-square metre apartment is dotted with orbs and circles. Some serve a purpose as mirrors or lights, while others are simply decorative wooden sculptures placed on the floor.

"We tried to soften the severity of the minimalist architecture with smooth outlines and rounded shapes," said Priyanka Itadkar, who co-founded The Act of Quad together with Falguni Bhatia.

"The objective of staging the spheres around the apartment was to generate a storyline from the sphere's perspective as if the orb was tumbling and travelling around the home, discovering every corner and object."

Geometric, custom-made furniture decorates the open floor plan, punctuating the creamy, neutral interior with bursts of warm orange and yellow.

This game of opposites was designed to consolidate the family's various different tastes into one cohesive whole.

"The grandfather, being a cartoonist, really wanted a playful environment in contrast to the minimal taste of his engineer son," Bhatia told Dezeen.

"The family desired a minimal but playful design, which was the opposite of their current old fashioned and ornamented home, made in the late 1940s."

In the entrance hall, a decorative wooden sphere clings to a corner next to the door while underneath, a console table with a contrasting white orb balanced on top wraps itself around the same wall.

The foyer opens up into a large open-plan living and dining room, as well as a kitchen that can be hidden behind sliding partition walls.

Characterised by its symmetrical set-up, the main room features a round dining table with a hemispherical base on one side and a circular coffee table surrounded by curved benches on the other.

The two areas are divided by a wavy screen in gradient colours that evoke a sunrise.

This same undulating silhouette is picked up in a handmade column, which winds and twists its way from floor to ceiling next to the TV.

From the central communal area, the apartment unfurls in two opposite directions. One wing houses the parents and grandparents, as well as a temple and family room, while the daughter's room occupies the other wing alongside a guest bedroom and study.

After itemising all of the family's household items, the studio incorporated plenty of storage into the plan to ensure that everything could be stowed away in its designated place.

The Act of Quad designed and fabricated most of the furniture and artworks in situ, in order to integrate them seamlessly into the architecture.

"We have derived the art from the space to make it feel like it's a part of the space," Bhatia explained.

In addition, a number of intricate woodwork pieces were brought over from the family's old home and refurbished to create a sense of continuity.

Among them is a chair with turned legs and spindles that is housed in the apartment's own temple, known as a mandir.

Here, a small antechamber leads to the inner shrine, which is crisscrossed by intersecting white arches and houses a statue of Hindu deity Krishna.

Other Indian architects who have brought places for worship into the home include Saket Sethi, who has created a home with an egg-shaped garden temple on the outskirts of Mumbai.
