You can read the history of Henley-on-Thames in its materials. Walk up from the river and the buildings tell you exactly where you are — flint pulled from the chalk of the Chilterns, warm red-orange brick fired from local clay, and timber frames that predate both. The Grade I listed bridge that crosses the Thames here, built in 1786 with its carved figures of Isis and Tamesis watching the water pass between five stone arches, is perhaps the single most expressive piece of architecture in the town. It connects Henley to the river that made it prosperous, and it does so with a confidence and grace that says something important about what good design can achieve when it truly belongs to its place.
That relationship between landscape, material and building is what draws me to Henley as an architect. This is a town shaped by the chalk hills that rise behind it and the river that flows through it, and the best architecture here has always understood that connection — drawing its materials from the ground beneath it and its character from the water at its edge. It is the foundation of how we work at Gresford Architects: architecture that reads the materials and the landscape, and belongs to this place rather than being imposed upon it.
An Award-winning Practice Rooted in Conservation and Sustainability
I founded Gresford Architects in London in 2006, and we are now based at the Oxford Eco Centre in Osney Mead. Ours is a deliberately small practice — I lead every project personally — but the range of expertise we draw on is broad. My RIBA Chartered and ARB Registered status is the professional foundation, but it is my membership of the Society for the Protection of Ancient Buildings that most shapes how we approach a town like Henley, where around three hundred buildings are listed and the Chilterns National Landscape wraps around the town on three sides. SPAB teaches you to understand a building before you change it, to read its construction history in the fabric itself. Combined with our Passivhaus Trust membership and Green Register accreditation, it means we can hold conservation sensitivity and environmental ambition in the same hand — which is precisely what Henley's architecture demands.
That combination has produced work we are proud of. The Deerings, a certified Passivhaus home in Hertfordshire, won a RIBA East Award in 2018 — a project that proved you can build to the most exacting energy standard and still create something architecturally generous. The Old Water Tower was shortlisted for a RIBA South Award in 2016. I was a finalist for Sustainability Architect of the Year at the Building Design Awards in 2018 and a judge for the British Homes Awards in 2025. Our projects have appeared in Dezeen, The Modern House Journal, and Grand Designs Magazine. What matters for Henley-on-Thames is not the recognition itself but what it represents: a practice that has spent nearly twenty years learning how to make buildings that are comfortable, designed to last, and genuinely responsive to the places they inhabit.
Working with Henley's Riverside Heritage and the Chilterns Landscape
Renovations in Henley demand a particular kind of care. A flint wall moves moisture differently from a brick wall. A Georgian facade over timber frames requires understanding how those systems talk to each other — how water breathes through old fabric, how loads distribute, where heat escapes. Our SPAB training equips us to read a building's construction history and work with it rather than against it. That means breathable materials where the fabric needs to breathe, careful structural interventions that respect original load paths, and detailing that acknowledges the building's past while improving its future.
Extension Design in Henley-on-Thames often means working within the conservation area, where proposals are rightly scrutinised. We welcome that scrutiny. The constraint of designing an extension that sits comfortably alongside flint-and-brick walls, that respects the proportions and materials of its host building, and that genuinely improves how a family uses their home — that is exactly the kind of architecture we find most rewarding. The Chilterns Buildings Design Guide sets out clear expectations for new development within the National Landscape, and our approach to materials and form aligns naturally with its emphasis on local character and high-quality design.
Sustainable Design is the principle that connects all of our services, and in Henley-on-Thames it takes on a particular character. The Chilterns National Landscape designation means that any new development here must meet the highest standards of design quality — not just in appearance but in how a building performs over decades. PassivHaus Design is our most rigorous answer to that challenge. It demands meticulous attention to insulation, airtightness, and the elimination of every thermal bridge, but the result is a home that is warm and stable without relying on conventional heating — quiet, comfortable, and remarkably economical to run. In a town where most homes were built long before energy efficiency was a consideration, that standard of performance is not an indulgence — it is what the building owes to the people living in it.
EnerPHit offers a certified retrofit pathway for the many older homes in Henley that cannot achieve full Passivhaus levels but deserve a serious upgrade in comfort and performance. For a Victorian or Edwardian house — or one of the mid-century homes that expanded the town in the decades after the war — the transformation in warmth, air quality, and running costs can be profound. New Build Design for sites within or around Henley-on-Thames must respond to the Chilterns National Landscape designation, which requires development of the highest quality that respects the natural beauty and built heritage of the area. For sites in open countryside beyond the town, Paragraph 84 of the National Planning Policy Framework provides a route to building something truly outstanding — a home that significantly enhances its setting and reflects the highest standards of architecture.
Henley-on-Thames has been shaped by its river and its hills for nearly a thousand years. The flint, the brick, the timber — they are still here, still working, still telling the story of a town that has always built with what the landscape provides. Whether you are renovating a listed property on Hart Street, extending a family home within the conservation area, retrofitting a Victorian house for modern comfort, or exploring what is possible on a new site in the Chilterns, I would welcome the chance to talk about what your building could become.
