During a restoration of the Church of St John the Baptist in Granborough, a pewter Chrismatory box was found concealed within the nave wall — a fifteenth-century vessel for holy oils, one of only two pre-Reformation examples of its kind known in England. I find that image compelling: a building holding something precious inside its fabric for centuries, unseen, waiting. It says something about the way buildings accumulate meaning quietly. Granborough itself has that quality. A settlement given to St Albans Abbey by King Offa in 792, its lanes still lined with thatched cottages and timber-framed farmhouses that have grown old slowly, each generation adding a chimney stack here, a brick repair there, without ever breaking the thread. For an architect, that patience is instructive. The best work in a place like this does not announce itself — it continues what is already there.
Award-winning Architects in Granborough
A Practice Shaped by Heritage and Sustainability
I founded Gresford Architects in London in 2006, and we now work from our Oxford studio with clients across the country. Our work sits at the point where heritage sensitivity meets environmental performance — what I think of as the marriage of the poetic and the practical. The Deerings, our Passivhaus home in Hertfordshire, won a RIBA East Award, and I was shortlisted for Sustainability Architect of the Year at the Building Design Awards. Our projects have been featured in Dezeen, The Modern House Journal and Grand Designs Magazine. As an ARB registered and RIBA Chartered architect, I am also a member of the Society for the Protection of Ancient Buildings, accredited with The Green Register and a member of the Passivhaus Trust. In 2025 I was invited to judge the British Homes Awards. That breadth of experience — from conservation repair to Passivhaus certification — matters in a village like Granborough, where the buildings ask for both care and ambition.
Working with the Built Character of Granborough
Granborough has seventeen listed buildings within the parish, concentrated around the junction of Marston Road with Church Lane and Green End. Many are thatched cottages and timber-framed farmhouses dating from the sixteenth and seventeenth centuries — Sparrows Thatch, Rose Cottage, The Leys — with brick chimney stacks and open fireplaces that speak of a time when heating was simple and fuel was plentiful. Renovations in this context mean understanding how these buildings were constructed: timber frames that flex, lime mortars that breathe, thatch that sheds water while allowing moisture to escape. My training with the Society for the Protection of Ancient Buildings shapes how we approach this work — repair rather than replace, and always let the building guide the intervention.
A thatched cottage with seventeenth-century brick chimney stacks and open fireplaces was built for a world where fuel was plentiful and draughts were simply endured. That world has gone, but the buildings remain — and they deserve better than the choice between spiralling heating bills and losing the character that makes them worth keeping. EnerPHit is the Passivhaus standard for existing buildings, and for homes in Granborough it offers a rigorous route to comfort and efficiency that respects what is already there. Breathable insulation fitted internally where thatch and lime render make external changes impractical, high-performance glazing set carefully into existing openings, airtightness improvements that work with the building rather than against it. The principle is straightforward: an old building does not need to become a new one. It needs to perform as well as one.
Extension Design for homes in Granborough requires a careful reading of what is already there. A sixteenth-century timber-framed cottage asks for something different from a later brick farmhouse, and the extension must respect the scale, materials and rhythm of its host. Buckinghamshire Council handles planning applications for the parish, and with no conservation area designation the process is often more flexible than homeowners in Granborough expect — though the presence of listed buildings and the village's neighbourhood plan mean that design quality still matters. We see those constraints as creative starting points, not obstacles.
Paragraph 84 of the National Planning Policy Framework provides an exceptional route for new homes in the open countryside, and the rural land around Granborough — the open fields and hedgerows of this quiet corner of north Buckinghamshire, where arable farming gave way to pasture after the enclosure of 1796 — sets a distinctive context for this kind of design. A dwelling under this policy must be truly outstanding and demonstrate sensitivity to its landscape. Here, that means understanding the low, settled scale of the village, the way its buildings sit within rather than above the land, and the materials traditions of the area. New Build Design and PassivHaus Design apply where new dwellings are proposed, and our RIBA award-winning work at The Deerings demonstrated that the highest standards of energy performance and genuine architectural quality are natural partners.
Sustainable Design is not a separate service we offer — it is the thread that runs through everything, from the earliest sketch to the finished building. In a village where buildings have drawn on local timber, clay and thatch for over a thousand years, sustainability is not an imported concept. It is the continuation of a tradition that Granborough's builders understood instinctively: use what is close to hand, build to last, waste nothing.
Granborough is a village that has accumulated its character quietly — layer upon layer, century by century, each addition respecting what came before. That is the kind of architecture we believe in. If you are considering a renovation, an extension or a new home in Granborough, we would welcome the conversation.
