Who We Are
With over 70 years of experience in the creation of luxury residences, we specialise in delivering original architectural and interior design, fully supported by our integrated fit-out and manufacturing services.
Working with private clients around the world, we translate ambitious visions into distinctive homes—each one tailored to reflect individual character, values, and lifestyle, while upholding the highest standards of design, craftsmanship, and execution..
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.
Our Heritage of Craftsmanship
From our workshops in the Cotswolds, our skilled craftsmen produce refined furniture, cabinetry, and specialist joinery for discerning clients around the world.
By integrating design and manufacturing from the outset, we ensure every piece we create is both architecturally aligned and functionally considered—supporting a cohesive, holistic approach to interior realisation.
“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.”
