Walk through Blewbury and the ground tells you how to build here. The village sits at the foot of the North Wessex Downs where chalk springs rise and thread streams through the lanes, and for centuries the people who lived here took that chalky earth — mixed it with straw, sand and dung — and raised cob walls from it, thatching the tops to keep the rain off. Some of those walls still line the footpaths today, lime-rendered and weathered but standing, protected from rising damp by stone bases and from above by their straw caps. It is architecture at its most elemental: the ground, shaped by hand, becoming structure. That idea — building from what is already here, responding to the material reality of a place — is at the heart of everything we do at Gresford Architects. Blewbury makes the principle visible in a way that few villages can.
Award-winning Architects in Blewbury
Why Homeowners in Blewbury Trust Gresford Architects
I founded Gresford Architects in London in 2006, and we are now based at the Oxford Eco Centre in Osney Mead — close enough to villages like Blewbury to know their character well. As a RIBA Chartered Architect, ARB-registered and a member of the Society for the Protection of Ancient Buildings, I bring a particular sensitivity to places where the fabric itself is the story. Our EnerPHit retrofit of The Old Orchard in Oxfordshire — featured in The Modern House Journal and The Spaces — showed how a period building can gain modern comfort without losing its identity. The Deerings in Hertfordshire, a Passivhaus new build, won a RIBA East Award in 2018. In 2018 I was also 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. Accredited by The Green Register and a member of the Passivhaus Trust, we bring the same care to a thatched cottage renovation in Blewbury as to a new build on open downland.
Architectural Services Shaped by Chalk, Cob and Conservation
The Vale of White Horse District Council handles planning for Blewbury, and the village adopted its Neighbourhood Plan in 2016, giving the community a clear voice in how development is managed. With over seventy listed buildings, a designated conservation area divided into five distinct character areas, and the North Wessex Downs National Landscape as its backdrop, any project here requires careful reading of the planning context before pen touches paper.
Renovations sit at the centre of what Blewbury needs from an architect. The village's building stock ranges from the Norman nave and sanctuary of St Michael the Archangel — a Grade I listed church transformed into a cruciform plan around 1190 — to timber-framed houses like Hall Barn, dating from around 1660, and the cruck cottage on South Street. Many of these buildings use materials that demand specific understanding: cob walls that need to breathe, lime renders that work with moisture rather than trapping it, structural timbers that have carried loads for centuries. My SPAB membership reflects how we approach this work — reading the building before proposing any change, understanding the movement of moisture through solid walls, and ensuring that every intervention respects what has survived.
EnerPHit is the natural companion to renovation work in Blewbury. The older homes here — cob, chalk block, timber frame — were not built with thermal performance in mind, and conventional insulation applied without understanding can cause real damage, trapping moisture in walls that were designed to dry naturally. EnerPHit works from the inside, creating a carefully detailed thermal envelope that improves comfort, air quality and energy efficiency while leaving the external character of the building untouched. The thatched rooflines, the lime-washed cob, the weathered stone bases — all remain exactly as they are.
Extension Design in Blewbury means working within a village where streams thread between buildings and plots have evolved organically over centuries. The streets wind rather than grid, and the relationship between buildings, garden walls, and water is intimate and specific to each site. An extension here needs to understand those relationships — the proportions of a cob-walled boundary, the way a chalk stream shapes the garden, the roofline that sits against the Downs beyond. It is detailed, responsive work, and the kind we find most rewarding.
For new homes in or around Blewbury, Sustainable Design and New Build Design draw on the same principle the cob walls embody: build with the place, not against it. PassivHaus Design offers a fabric-first approach to energy performance — stable internal temperatures, minimal running costs, excellent air quality — that sits comfortably alongside the village's long tradition of building from local materials with local knowledge. For sites in the open downland beyond the village, Paragraph 84 of the National Planning Policy Framework provides a route for architecturally outstanding homes where the design itself justifies the location, and the North Wessex Downs landscape is exactly the kind of setting where that ambition belongs.
Blewbury is a village that has always known how to build from what the ground provides — chalk, earth, straw, stone. If you are considering a renovation, extension or new home here, we would welcome the conversation about how to continue that tradition well.
