Buildings are experienced in time.
We design for the fourth dimension.

The Practice

We don't have a signature style. We have a signature outcome — sukoon.

4th Dimension is a multi-disciplinary design practice founded in Surat in 2002 by Ar. Deepak Sahajwani. For over two decades we have designed residences, interiors, and commercial spaces for clients across India — from Mumbai to Chennai, Coimbatore to Lonavla.

What defines our work is not a material or a palette — those evolve with every project and every era. It is our ability to listen to a client's hopes and translate them into space. Every project is different because every client is different. What never changes is what we hold the design to: openness, minimalism, and comfort.

How We Design

Design is not the play of materials. It is the experience of living.

A home should offer sukoon — a word with no exact English equivalent, somewhere between peace, ease, and stillness. That is what we design toward: spaces that are open, uncluttered, and deeply comfortable to live in, day after day, year after year.

The materials change with every project. The discipline doesn't: openness, minimalism, comfort. Currently our work leans tonal and texture-led — but that is today's expression of the philosophy, not the philosophy itself.
