There is something telling about a town whose High Street is shaped like a boat. Walk Thame's broad central thoroughfare from end to end and you are tracing a piece of deliberate medieval planning — a wide, curving space laid out in the twelfth century by the Bishop of Lincoln specifically to accommodate a market. That market has run continuously since 1183, and the town received its Royal Charter in 1215. But what strikes me most about Thame is what has happened to the buildings that line that space over the centuries since. Many of the structures along the High Street began as timber-framed houses in the sixteenth and seventeenth centuries, only to be refronted with Georgian brick facades a hundred years later. Strip back the surface and the old frames are still there — oak posts and beams carrying the weight of a building that has been quietly reinvented without losing its bones.
That kind of layering is endlessly interesting to me as an architect. It tells you that people in Thame have always understood something important about buildings: that they are not fixed objects but things that evolve, that can be improved and adapted without being erased. It is exactly the principle that drives our work at Gresford Architects, whether we are working with a listed property in the conservation area or designing something entirely new on the edge of this growing town.
Trust Built on Heritage and Performance
I founded Gresford Architects in London in 2006, and we are now based at the Oxford Eco Centre in Osney Mead — a deliberately small practice where I lead every project personally. I am a RIBA Chartered and ARB Registered architect, and my membership of the Society for the Protection of Ancient Buildings reflects a deep commitment to understanding historic structures on their own terms, not imposing modern assumptions on old fabric. I am also accredited with The Green Register and a member of the Passivhaus Trust, because I believe the most interesting architecture happens where heritage sensitivity and environmental performance meet.
That conviction has shaped our most recognised work. The Deerings, a certified Passivhaus home in Hertfordshire, won a RIBA East Award in 2018 — proof that rigorous energy performance and architectural quality are not competing ambitions. The Old Water Tower was shortlisted for a RIBA South Award in 2016. Our projects have been featured in Dezeen, The Modern House Journal, and Grand Designs Magazine. In 2018 I was a finalist for Sustainability Architect of the Year at the Building Design Awards, and in 2025 I served as a judge for the British Homes Awards. We bring this breadth of experience to every project in Thame, from the most sensitive listed building to the most ambitious new home.
Architecture That Reads the Layers
Thame's conservation area is home to over 180 listed buildings, and working here means understanding how those layers of history sit together. The Grade I listed Church of St Mary the Virgin anchors the southern end of the High Street with its thirteenth-century nave arcades and Perpendicular Gothic tower. The fifteenth-century Birdcage Inn is among the timber-framed survivors that give the town its texture, and the Spread Eagle — with its early eighteenth-century brick facade — is another reminder of how Thame's buildings have been reinvented across the centuries. And then there are the Georgian refrontings — elegant brick facades that transformed the streetscape in the eighteenth century while preserving the older structures behind them. Each building tells a different story about how Thame has adapted over time, and each one demands a different architectural response.
Renovations in this context require patience, knowledge, and genuine respect for what already exists. A timber-framed building behaves differently from a Georgian brick house — moisture moves through the fabric in different ways, structural loads are distributed differently, and the original builders had different intentions. Our SPAB training means we approach each building by asking how it was designed to work, not just what we want it to become. That understanding shapes everything from specification of breathable lime mortars and insulation to the positioning of new openings and the treatment of historic joinery.
Extension Design in Thame often involves navigating the relationship between a historic frontage and a rear that has already been altered more than once. Proposals within the conservation area are rightly scrutinised, and that scrutiny is something we welcome. The discipline of designing an extension that respects the scale, materials, and proportions of its host building — while genuinely improving how the home functions — is one of the most rewarding things we do. A well-designed extension does not compete with the original. It completes it.
For the many older homes in Thame — including the post-war housing that expanded the town through the mid-twentieth century — EnerPHit offers a transformative approach to retrofit. The certified standard treats a house as a complete thermal system, upgrading insulation, airtightness, and ventilation to bring performance as close to Passivhaus levels as the existing structure allows. For homeowners in Thame living in a draughty 1950s or 1960s house, the difference is not incremental. It is a fundamental shift in comfort, running costs, and carbon footprint.
Designing for Thame's Next Chapter
Thame is entering a significant period of growth. The South Oxfordshire Local Plan has allocated 753 additional homes to the town, and the Thame Neighbourhood Plan 2 — adopted at referendum in February 2025 — sets out how that growth should be shaped. This is a town that has always been planned with care, from the Bishop of Lincoln's twelfth-century market layout to the community-led neighbourhood planning of today. New Build Design in Thame should honour that tradition — homes that belong to their place, that respond to the materials and proportions of the town's existing fabric, and that perform well enough to be genuinely comfortable for decades to come.
Sustainable Design is the thread that connects everything we do. It means homes that are comfortable, designed to last, and built to use energy and materials as efficiently as possible. PassivHaus Design takes that commitment to its most rigorous expression — a certified standard delivering around ninety per cent less heating energy than a conventional new build, achieved through meticulous attention to insulation, airtightness, thermal bridge-free construction, and mechanical ventilation with heat recovery. Our RIBA award-winning Passivhaus project, The Deerings, is not a theoretical exercise. It is a home that is warm, quiet, and remarkably economical to run — the kind of home that Thame's new developments should aspire to.
For sites beyond the settlement boundary — in the countryside surrounding Thame where the Oxfordshire landscape opens out towards the Chilterns — Paragraph 84 of the National Planning Policy Framework offers a route to building something exceptional. The bar is deliberately high: the design must be truly outstanding, must reflect the highest standards of architecture, and must significantly enhance its immediate setting. But for the right client and the right site, it is an extraordinary opportunity.
Thame has been shaped and reshaped for nearly a thousand years, always with intention, always with an eye to what the town needs next. Whether you are restoring a timber-framed building on the High Street, extending a family home, retrofitting a mid-century house for modern comfort, or building something new as the town grows, I would welcome the chance to talk.
