There is a detail about Denham Parish that still catches me every time I think about it. In 1936, Alexander Korda opened his film studios here on a site beside the River Colne, and the architects he commissioned to design them were Walter Gropius and Maxwell Fry — Gropius, the founder of the Bauhaus, working in a quiet corner of Buckinghamshire. The studios are gone now, mostly demolished by 1981, but something of that ambition lingers in the idea that good design can arrive anywhere, not just in cities. New Denham itself grew up along the Oxford Road as a twentieth-century settlement, its character shaped less by medieval lanes and parish churches than by the canal, the railway and the practical needs of people making their lives between Uxbridge and the Chilterns. That straightforwardness appeals to me. These are homes that were built to be lived in, and they deserve architecture that takes them seriously.
Award-winning Architects in New Denham
An Architect's Practice Built on Craft and Sustainability
I started Gresford Architects in London in 2006, and we now work with clients across the country from our studio in Oxford. What interests me about places like New Denham is the honesty of the housing — homes built in the last century with solid construction and practical layouts, the kind of buildings that reward intelligent improvement rather than wholesale reinvention. We are a RIBA Chartered practice and ARB registered, with dual expertise that suits this stretch of Buckinghamshire well: I am a member of the Passivhaus Trust and accredited on The Green Register, committed to buildings that use energy and materials as efficiently as possible, and a member of SPAB, the Society for the Protection of Ancient Buildings, which sharpens the eye for how any building — not just a medieval one — was put together and how it can be made to work harder. Our projects have been recognised with a RIBA East Award for The Deerings, a Passivhaus home in Hertfordshire, featured in Dezeen and Grand Designs Magazine, and in 2025 I served as a judge at the British Homes Awards. That breadth matters when the challenge is making a mid-century semi in New Denham perform like a building designed yesterday.
Extensions, Retrofits and New Builds in New Denham
Extension Design is often the most practical starting point for homes in New Denham, where many of the houses date from the mid-twentieth century and were built with the proportions and layouts of their era — generous plots, but rooms that no longer quite fit the way families live today. A well-designed extension is not simply about adding floor area; it is about rethinking how a home connects to its garden, how light moves through the day, and how new and existing spaces work as a whole. Buckinghamshire Council handles planning applications for New Denham, and because the settlement sits outside the Green Belt — unlike the neighbouring villages of Denham Village and Higher Denham, which are washed over by it — there is generally more scope for sensitive extensions and alterations than in the more constrained parts of the parish.
Sustainable Design is the thread that runs through every project we take on, the conviction that buildings which use energy and materials efficiently are also more comfortable to inhabit, more economical to run and more joyful to live in. For homes in New Denham, this means thinking carefully about insulation, glazing orientation, airtightness and ventilation — not as technical afterthoughts, but as the starting points of any design. PassivHaus Design takes this furthest, setting a measurable standard for energy performance that virtually eliminates the need for conventional heating. Where clients are building new or undertaking a major extension, we design to PassivHaus principles wherever the site and budget allow.
EnerPHit offers something equally transformative for the existing housing stock in New Denham. The semi-detached houses and terraces that line the Oxford Road and its side streets were built from the 1930s onwards with cavity walls that were never insulated, single-glazed windows and minimal draught-proofing — sound structures, well-built for their time, but losing heat at a rate their original builders never had to worry about. These are not tired properties ready for demolition; they are fundamentally good homes with generous proportions and solid bones. EnerPHit brings them up to Passivhaus-level performance through better insulation, airtightness and mechanical ventilation with heat recovery, the kind of retrofit that makes a house warmer, quieter and dramatically cheaper to heat while keeping everything that already works. It is the practical marriage of old construction and new science, and for a settlement built on practicality, that feels right.
Renovations across the wider Denham parish sometimes bring their own particular challenges, especially where older properties sit within or near the Denham Conservation Area, first designated in 1971. Here the historic fabric — timber-framed cottages, red-brick houses with clay tile roofs, the flint and brick that characterises so much of south Buckinghamshire — requires a different kind of attention. New Build Design, meanwhile, offers the opportunity to build to the highest environmental standards from the ground up, whether on an infill plot within New Denham or a larger site elsewhere in the Colne Valley. For open countryside beyond the settlement boundary, Paragraph 84 of the National Planning Policy Framework provides a route for truly exceptional homes where the quality of the architecture itself justifies planning permission — the kind of brief where sustainability and ambition meet.
What draws me to New Denham is the same thing that drew Korda here in the 1930s — the sense that something genuinely good can be built in a place people might overlook. The canal, the railway, the practical housing stock along the Oxford Road — these are the foundations of a community that values substance over show. Whether you are thinking about an extension that changes how your family uses your home, a retrofit that makes it warmer and far cheaper to run, or a new build designed to the highest environmental standards, we would welcome the conversation.
