70 Years, and Counting
Founded by Edwin Bonham in 1948, Bonham & Bonham began with a singular vision: to create exceptional spaces through the seamless integration of architecture, construction, and interior design.
Today, that legacy continues under the leadership of Chairman David Bonham and third-generation Managing Director James Bonham, supported by a visionary design team based in the heart of Belgravia.
Renowned for delivering original design of the highest calibre, we are the trusted partner for private clients seeking bespoke homes that reflect their values, lifestyle, and aspirations.


We offer a fully integrated approach, combining expert design with main contracting and fit-out services to deliver cohesive, high-quality results from concept to completion.
With in-house manufacturing and a dedicated joinery workshop, we produce everything from bespoke cabinetry to custom lighting and textiles—crafted to the highest standards.
Led by senior designers with regular on-site involvement, each project is executed with precision and attention to detail, ensuring the original vision is realised exactly as intended.
From the UK to the Mediterranean, Middle East, Caribbean, and beyond, we bring our expertise, discretion, and meticulous attention to detail to projects across the globe.


“Bonham and Bonham are committed to absolute quality, from initial interior design concepts through to detailed illustrations, drawings and the production of superbly finished furniture and fittings. It is rare indeed to find a one-stop design, manufacturing and build company that work to such a high standard.”
