Keystone Studio

Homes designed for multiple generations aren’t just about sharing space.
They’re about balancing togetherness, privacy, care, and independence - beautifully.

Thoughtful architecture creates room for every generation to feel connected, comfortable, and at ease.

Because inclusive design isn’t a feature.
It’s a way of living better together.

What We Do?

We design spaces that transform your ‘needs and preferences’ into ’aesthetic and functional architecture’.

We blend ‘Spaces’, ‘Light’, ‘Colors’, ‘Materials’, and ‘Textures’ to create ‘homes’, ‘workspaces’, and ‘institutions’ that foster a sense of harmony through design.

Project Showcase | ‘Home of Mr.Prasanth & Simmi Prasanth’ - Bengaluru

Located in the upmarket gated community of Beverly Hills in Bengaluru, the house was designed as the primary residence of Mr. Prasanth and family, with the lush green park view serving as the major focus.

The clients’ love for gardening inspired the design, with the home oriented toward the lush green community park, creating a seamless connection with nature and making the plot feel larger through the borrowed openness of the park.

Elevated above the street, the living area opens to the park through generous windows on two sides, while the car parking is tucked quietly in the basement, leaving the greenery uninterrupted and filling the space with light. 

The interiors were kept subtle with plain white walls as primary base and a contrast of wooden floors. The result is a home where every space is connected to light, nature, and a sense of calm.
