Interior design and interior architecture for people who want spaces that work as well as they look.

London. Home Counties. International.

STUDIO INTRODUCTION

Marsham Studio is a luxury interior design and interior architecture practice led by Tom Cottrell. We work across residential, hospitality, and commercial projects — from family homes in the Home Counties to boutique hotels in the Mediterranean.

Our approach starts with how you live, not how a room should look. We design backwards from the reality of your day-to-day — the school runs, the Sunday lunches, the Monday morning meetings — and build spaces that meet those moments with intelligence and beauty.

The result is interiors that feel considered, not contrived. Refined, but lived in.

WHAT WE DO:

We offer a full design service across five disciplines: interior architecture, FF&E design, design management, landscape design, and full turnkey delivery. Every project is structured around the same rigorous process, whether it’s a city apartment or a country estate.
