When the floor of St Peter's was lifted in 1986, the builders found Saxon mortar still bonded to flint rubble footings beneath the nave — evidence that a stone church had stood on this ground since at least the late eleventh century. The lower walls of the present nave are that same Saxon structure, absorbed into a building that grew around it: Norman arches cut through the north wall in the twelfth century, Early English bays added to the south in the thirteenth, an embattled tower raised to the west, and George Gilbert Scott's careful restoration drawing it all together in 1848. What interests me about Iver is how each generation built with what was already there rather than starting again. The flint that the Saxons laid is the same material you see in walls throughout the village today, and that continuity — quiet, practical, unselfconscious — tells you something important about how buildings in this place have always worked.
Award-winning Architects in Iver
Trusted Credentials for Layered Buildings
I founded Gresford Architects in London in 2006, and we are now based in Oxford, working with clients throughout England. We are ARB registered and RIBA Chartered, and the work has been recognised with a RIBA East Award for The Deerings — a Passivhaus home — and a RIBA South Awards shortlisting for The Old Water Tower. In 2018 I was a finalist for Sustainability Architect of the Year at the Building Design Awards, and in 2025 I served as a judge at the British Homes Awards. Our accreditations with the Passivhaus Trust and The Green Register reflect a commitment to energy performance that is tested and measurable, while my membership of SPAB — the Society for the Protection of Ancient Buildings — shapes how we approach the kind of layered, historically sensitive buildings that Iver has in abundance.
Architectural Services Shaped by Iver's Character
Renovations are central to working well in Iver. The conservation area contains Grade I listed St Peter's alongside Grade II listed buildings including the sixteenth-century Swan Hotel and several houses from the seventeenth and eighteenth centuries. Working with these properties means reading the accumulated layers — understanding where earlier fabric sits within later alterations, where lime mortars are needed to let historic walls breathe, and where previous interventions may have done more harm than good. My training with SPAB informs this approach: we repair rather than replace, respect each phase of a building's life, and treat the evidence of past craftsmanship as something to be revealed rather than concealed.
EnerPHit is particularly relevant in Iver, where the older cottages and Georgian houses that give the conservation area its character were built long before thermal performance entered the conversation. An EnerPHit retrofit upgrades insulation, seals the building envelope and introduces heat recovery ventilation, bringing stable temperatures and significantly lower energy bills while the building's historic face remains untouched. In a conservation area where flint walls and traditional frontages must be preserved, this internal-first approach is especially valuable — the street sees what it has always seen, but the home behind it performs to modern standards.
Extension Design matters in a village where Green Belt policy limits outward growth and many families need to make the most of the homes they already have. We design extensions that bring daylight deeper into existing plans, connect living spaces to gardens, and use materials — flint, brick, timber — that sit comfortably alongside what is already there. The best extensions in a place like Iver do not announce themselves; they feel as though they have always been part of the house.
Sustainable Design runs through all of our work, from the orientation of a building to the sourcing of its materials. PassivHaus Design takes this further still, creating homes with exceptionally low energy demand through rigorous attention to airtightness, insulation and the elimination of thermal bridges. For those considering a new home in the countryside around Iver, New Build Design offers the chance to build something that responds to the landscape from the outset, and Paragraph 84 of the National Planning Policy Framework provides a route for truly exceptional residential architecture in rural settings — homes whose design quality justifies their place beyond existing settlement boundaries.
Whether you are renovating one of the older buildings in the village, extending a family home within the Green Belt, or planning something entirely new in the Colne Valley landscape, we would welcome the conversation. The best architecture, like the best of Iver's own building tradition, works with what is already there — and that has always been our starting point.
