Our approach

The best buildings come out of the room, not the drawing board.

The best buildings come out of the room, not the drawing board.

We believe the strongest projects come from genuine collaboration between architect, client and consultant. Site conditions, programme, budget and sustainability all shape a scheme — our work is to turn them into a clear three-dimensional answer.

Our architects and specialist consultants work together from the earliest stage, so a design is tested for structure, energy, cost and buildability before it is ever presented. Regular meetings with you refine those early concepts into one well-defined solution.

Architecture does not stop at the site boundary. Subbiah and Sunayana write, speak and sit down with the industry — on how buildings actually get delivered in India, what sustainability costs in practice, and what a young practice learns on a live site.

Sustainability in Building Construction

Knauf India recently hosted an insightful panel discussion on "Sustainability in Building Construction”. The conversation highlighted the pivotal role of individual actions and government policies in shaping a sustainable future. Key takeaways from the panel included the importance of sustainable design principles like natural lighting, efficient ventilation, and reduced energy consumption. We also discussed the urgent need for circular economy practices and the reduction of embodied energy in building materials.

How We Work

Ideas get better when disciplines collide.

Architecture, engineering, interiors and technology don’t take turns at DIUS. They develop together. We sketch, question, test and resolve ideas as one team, because the best solutions rarely belong to just one discipline.

01

THINK TOGETHER

Architects, designers and engineers work on the same problem, at the same table, at the same time.

02

QUESTION THE BRIEF

We start by understanding how a place will really be used, before anything is drawn.

03

DESIGN WITH DETAIL

An idea is only as good as its details, so we carry it all the way through.

04

MAKE IT BUILDABLE

We design with how things are made in mind, so the idea survives the journey to site.

05

KEEP LEARNING

Design reviews, site visits and conversations across disciplines mean everyone learns from every project.

The Principals

Design is personal here. So is leadership.

Both directors are involved directly in design and delivery — which means you deal with the people actually making the decisions.
