Walk into Holy Trinity Church in Seer Green and you see the work of someone who understood flint. The walls are knapped — each stone split to expose its dark, glassy interior and set face-out with a care that no machine could replicate. The church was built in 1846, relatively late in the story of flint architecture, yet whoever laid those walls was drawing on a tradition as old as the Chilterns themselves. It is the same patience you find in the timber frame of Hall Place, the oldest standing building in the village, where a late sixteenth-century structure has accumulated red brick infill, tiled-over braces and weatherboarding across four centuries of use. Seer Green is a place where the materials tell you how long people have been paying attention — and that is something I respond to as an architect, because good buildings always begin with that kind of care.
Award-winning Architects in Seer Green
An Award-Winning Practice Working Across the Country
Gresford Architects has been designing homes for nearly two decades. I founded the practice in London in 2006, and we are now based in Oxford, working with clients across the country. We are RIBA Chartered and ARB registered, and our memberships of the Passivhaus Trust and The Green Register reflect a commitment to buildings that perform as well as they look. Our Passivhaus home in Hertfordshire, The Deerings, won a RIBA East Award in 2018, and I was a finalist for Sustainability Architect of the Year at the Building Design Awards the same year. My membership of SPAB — the Society for the Protection of Ancient Buildings — runs deep in the way we approach older buildings: with curiosity, restraint and a genuine respect for what previous generations got right. We have been published in Dezeen, Grand Designs Magazine and The Modern House Journal, and in 2025 I served as a judge at the British Homes Awards.
Designing for a Chilterns Village of Timber and Flint
Renovations are central to what we do, and in Seer Green the older buildings make the case for a thoughtful approach. Buckinghamshire Council is the planning authority here, and the village sits within the Chilterns National Landscape and the Green Belt — which together mean that every intervention is measured against the character of the place. But that is not constraint to resent; it is clarity to welcome. Hall Place, with its late sixteenth-century timber frame, has been repaired and adapted over centuries — each generation adding what was needed without erasing what came before. Seventeenth-century timber-framed buildings like Colliers and Peaceful Cottage carry the same layered quality. Seer Green's character was built by people who worked within the constraints of their own materials: flint that had to be knapped by hand, timber that had to be cut and jointed without power tools, brick that came from local clay. Working with buildings like these means understanding lime mortars, reading structural movement, and knowing when to intervene and when to leave well alone, continuing that tradition of care. My wife Phoebe is a conservation architect, and her influence has shaped the patience with which we approach every older building.
EnerPHit, our certified retrofit standard, brings these older buildings into the present without altering what the street sees. Solid-walled cottages that have stood for centuries were never designed for modern thermal comfort, but EnerPHit upgrades the building envelope — insulation, airtightness, mechanical ventilation with heat recovery — so that the interior becomes warm, stable and energy-efficient while the exterior remains exactly as it was. For timber-framed buildings in the Chilterns, where breathability matters as much as insulation, getting the details right is everything.
Extension Design is often the starting point for families in Seer Green. The village reads in two chapters: the older timber and flint cluster around the triangular green, and the Arts and Crafts homes that arrived after the railway halt opened at the end of 1914 and the village expanded through the 1920s and 1930s. Both chapters present different extension challenges. Near the green, where Hall Place and the listed cottages set the material tone, an extension needs to defer — flint, brick, clay tile, a roofline that does not compete. In the later streets, where tile-hung gables and rendered walls reflect the Chilterns Arts and Crafts tradition, the opportunity is different: more daylight, a stronger connection to the garden, materials that sit honestly alongside what the original builders chose.
Sustainable Design is the thread that runs through all of our work — buildings that are comfortable, designed to last, and use energy and materials as efficiently as possible. In a village like Seer Green, where the National Landscape designation demands sensitivity to the surrounding chalk and beechwood landscape, sustainability is not an add-on; it is the starting point. PassivHaus Design takes this to its most rigorous conclusion — homes with exceptionally low energy demand achieved through continuous insulation, precision airtightness and the elimination of thermal bridges. New Build Design, where Green Belt and National Landscape policies allow, offers the chance to respond to a specific plot rather than repeat a standard house type. And for those with ambitions in the wider countryside, Paragraph 84 of the National Planning Policy Framework provides a route for truly exceptional homes — where the quality of the architecture itself earns its place.
Whether you are renovating a timber-framed cottage, extending a home near the green, or planning something new within the Chilterns, we would welcome the conversation. Seer Green has been shaped by people who worked with care and patience — its lace makers, its flint knappers, its timber framers. Good architecture belongs in that tradition.
