What strikes me about Witney is how clearly you can read the relationship between industry and architecture. The Blanket Hall on the High Street, built in 1721 by the Company of Blanket Makers, is not just a handsome Cotswold stone building — it is a record of a town that organised itself around making things, that used its river and its wool and its skill to build something that lasted. Walk along Church Green towards St Mary the Virgin with its 154-foot spire, past the buttercross in the market square — built around 1600, its clock added in 1683 — and you are moving through a town whose prosperity and identity were shaped by the Windrush and the trade it powered for the better part of a thousand years.
That kind of place has a particular architectural integrity. The Cotswold stone gives Witney a material consistency that few towns of its size can match, and the scale of the former mill buildings and merchants' houses tells you this was never a sleepy village — it was a working town, confident and productive. I founded Gresford Architects in London in 2006 and we are now based in Oxford, just twelve miles east. Over almost twenty years we have built a practice around the conviction that the best architecture comes from understanding a place deeply — its materials, its history, its patterns of use — and designing with that understanding rather than against it.
Why Clients in Witney Trust Gresford Architects
We are a RIBA Chartered and ARB Registered practice with a particular depth of experience at the intersection of sustainable design and historic sensitivity. I am a member of the Society for the Protection of Ancient Buildings, which grounds our conservation work in a philosophy of careful, evidence-based repair rather than superficial restoration. I am also a member of the Passivhaus Trust and accredited with The Green Register — credentials that reflect the other side of what we do: designing buildings that perform exceptionally well in terms of energy, comfort and durability.
Our project The Deerings, a certified Passivhaus home in Hertfordshire, won a RIBA East Award in 2018. That same year I was a finalist for Sustainability Architect of the Year at the Building Design Awards. Our work has been published in Dezeen, The Modern House Journal, and Grand Designs Magazine, and in 2025 I served as a judge for the British Homes Awards. These are not decorations — they represent almost two decades of testing and refining an approach that treats sustainability not as a constraint but as a force to create homes that are more comfortable to inhabit, more economical to run and more joyful to live in.
Architectural Services for a Town Between Heritage and Growth
Extension Design is one of the most common starting points for homeowners in Witney. Many of the town's older properties — the Cotswold stone cottages and Victorian terraces that give streets their character — were built for a different era of family life, and the question of how to add space without losing what makes the home worth keeping is one we relish. The best extensions do more than add a room; they rethink circulation, bring daylight into the heart of a plan, and create a stronger relationship between inside and out. Within the Witney and Cogges Conservation Area, established from 1970 and extended several times since, this work requires a genuine sensitivity to context — to the stone, the rooflines, the rhythm of the street — that goes well beyond choosing the right materials.
EnerPHit is our approach to deep energy retrofit, and it is especially relevant for the older housing stock in Witney. Solid-walled Cotswold stone houses have a beauty that no one wants to lose, but they can be draughty, cold through the winter and expensive to heat. EnerPHit is a rigorous, measured upgrade to a building's thermal envelope — insulation, airtightness, ventilation — that transforms comfort and slashes energy bills while respecting the fabric and character of the original building. We have delivered certified Passivhaus projects and understand the building physics at a level that allows us to push performance without compromising what makes an older building special.
Sustainable Design runs through everything we do at Gresford Architects. It is not a bolt-on or an optional extra — it is the starting point for every project, whether a sensitive alteration to a listed cottage or a contemporary new home on the edge of town. Buildings should be comfortable, designed to last and built to use energy and materials as efficiently as possible. That conviction shapes every decision, from orientation and glazing strategy to the choice of insulation and the detailing of junctions.
New Build Design in and around Witney means responding to a town that is growing. Significant housing development is underway to the east and north of the town, and the West Oxfordshire Local Plan identifies Witney as a focus for future growth. For anyone building a new home here, the opportunity is to create something that belongs in the Cotswold landscape and performs to the highest contemporary standards — a home that uses the local stone palette and the proportions that make Witney coherent, while delivering the airtightness, thermal performance and low energy demand that modern building science makes possible.
PassivHaus Design is the gold standard for new-build energy performance. A Passivhaus home uses around ninety per cent less energy for heating than a conventional house, achieving remarkable comfort through meticulous attention to insulation, airtightness and mechanical ventilation with heat recovery. The local planning context here has been supportive of high-performance sustainable homes, and we have the track record to deliver them.
Renovations in Witney often involve navigating the particular challenges of Cotswold stone construction — understanding lime mortars, how moisture moves through solid walls, and how interventions made with the best intentions in one decade can create problems in the next. Our SPAB training informs every renovation project, ensuring that we work with the building's existing fabric rather than against it.
For sites in the countryside beyond Witney — the Windrush Valley, the rolling farmland towards the Cotswolds — Paragraph 84 of the National Planning Policy Framework offers a route to building exceptional homes in the open countryside. It is a demanding policy, deliberately so, but for the right site and the right ambition it opens a genuine opportunity to create architecture that enhances its rural setting.
Whether you are extending a cottage in the conservation area, retrofitting a Victorian terrace to transform how it feels and performs, or planning something new on the edge of town, I would welcome the chance to talk. The best projects begin with a conversation about the building, the place and how you want to live in it.
