These two villages sit a few miles north-east of Northampton, close enough to be neighbours but shaped by quite different forces. Overstone was remade by wealth — the entire village was relocated in the eighteenth century to make way for the park, moved from its medieval position around the hall to its present site along the Sywell Road, where the thatched cottages that survive today were built on fresh ground at the estate's northern edge. Sywell, whose name is thought to derive from seven wells, was rebuilt in the 1860s when Lady Overstone commissioned new cottages, a school and the rebuilding of the rectory — the kind of comprehensive Victorian estate patronage that gave a village architectural consistency at the cost of everything that came before. What interests me as an architect is the paradox in both cases: that destruction and displacement produced buildings of genuine quality, carefully planned and built to last, even as they erased the older settlement they replaced.

Conservation and Performance in Equal Measure
Gresford Architects was founded in London in 2006 and is now based in Oxford, working with clients across the country. I am an ARB-registered and RIBA Chartered architect, a member of SPAB, the Passivhaus Trust and The Green Register. The Deerings, a certified Passivhaus home in Hertfordshire, won the RIBA East Award in 2018, the same year I was named a finalist for Sustainability Architect of the Year at the Building Design Awards. The Old Water Tower was shortlisted for a RIBA South Award, and in 2025 I was invited to judge the British Homes Awards. Our work has been published in Dezeen, Grand Designs Magazine and The Modern House Journal — projects that share a conviction that heritage sensitivity and environmental performance are not competing priorities but aspects of the same ambition. In villages like Sywell and Overstone, where the housing stock ranges from Victorian estate cottages to modern development on the edges, that breadth of experience matters.

Renovations here begin with understanding which chapter of each village's story your house belongs to. In Overstone, the thatched cottages along the Sywell Road are the legacy of the eighteenth-century relocation — stone-built, carefully proportioned, and listed for good reason. The Church of St Nicholas, rebuilt in 1807 and remodelled in 1903, marks the edge of the old park. In Sywell, the estate cottages from the 1860s rebuilding sit alongside the Church of St Peter and St Paul, which is Grade II* listed with origins in the twelfth century and work spanning the thirteenth and fourteenth. Sywell Hall, probably dating from around 1600 with later additions, adds another layer. Working with any of these older buildings requires an understanding of their materials — how stone and thatch and lime mortar manage moisture, how they age, and why interventions that seal or stiffen the fabric do more harm than good. Sywell falls under North Northamptonshire Council for planning purposes, while Overstone is handled by West Northamptonshire Council.
EnerPHit, the Passivhaus Institute's certified retrofit standard, is well suited to the variety of housing across both villages. The Victorian estate cottages — solidly built but designed long before thermal performance was a consideration — present the kind of challenge EnerPHit was developed to address: solid walls that need vapour-open insulation, draughty junctions that need careful airtightness detailing, and a building envelope that can be dramatically improved without altering the character that makes these cottages worth preserving. For the more recent housing that has grown around both villages as Northampton has expanded, the gains from a full retrofit are even more straightforward — cavity wall insulation, high-performance glazing, and mechanical ventilation with heat recovery that together transform how the house feels to live in.
Extension Design for homes in these villages requires a careful reading of context. In Overstone, where the surviving cottages have a distinctive estate character — consistent materials, modest scale, thatched roofs — an extension needs to sit within that established language rather than compete with it. In Sywell, the range is broader, from the estate-era cottages to the later twentieth-century housing, and the design response should reflect which building you are working with. The best extensions make the whole house feel more resolved, responding to the proportions, materials and setting of the existing building rather than simply adding volume.
Sustainable Design runs through every project we take on, and in a place shaped by estate patronage it carries a particular resonance. The Victorian builders who remade Sywell understood material quality — they built with care because the estate demanded it, and those buildings have endured. That instinct, to build well enough that the question of replacement does not arise for generations, is the foundation of sustainable architecture. PassivHaus Design sets our benchmark for any new construction — certified thermal comfort with minimal energy demand. New Build Design in either village should respect the established character without mimicking it, bringing the performance standards of our own era to bear. For sites in the open countryside between the villages, Paragraph 84 of the National Planning Policy Framework provides a route to architecturally outstanding homes — but the design must be sensitive to a landscape that has already been reshaped once by estate ambition and should not be treated carelessly again.
Sywell and Overstone are villages that were remade by a single estate's vision — and what was built in that remaking has proved worth keeping. If you are considering a project in either village, we would welcome the conversation.
