There is a particular quality of light where the Chiltern escarpment meets the Vale of Aylesbury — the steep beechwood slopes giving way, quite suddenly, to open sky and flat farmland. Askett and Whiteleaf sit right at this threshold, two hamlets that belong to the hills and the vale in equal measure. The chalk beneath is never far from the surface here. You see it in the Whiteleaf Cross carved into the escarpment, a hill figure whose origins remain uncertain but whose presence has shaped this landscape for centuries. You see it, too, in the knapped flint walls that catch the light along Askett's lanes, and in the way buildings here have always been made from what the ground offers. As an architect, I find these edge-of-landscape settlements endlessly compelling — the geology shifts, the building traditions respond, and every structure has to negotiate between shelter and openness, between the intimacy of the hillside and the exposure of the vale below.
Award-winning Architects in Askett and Whiteleaf
Why Homeowners in the Chilterns Trust Gresford Architects
I founded Gresford Architects in London in 2006, and we now work from our studio in Oxford with clients across the country. Our work sits at the intersection of heritage understanding and environmental ambition — buildings that are comfortable, designed to last, and that use energy and materials as efficiently as possible. That philosophy has been recognised with a RIBA East Award for The Deerings, our Passivhaus home in Hertfordshire, and a shortlisting for Sustainability Architect of the Year at the Building Design Awards. As an ARB registered and RIBA Chartered architect, and a member of SPAB, the Passivhaus Trust and The Green Register, I bring the range of expertise that working in a sensitive landscape like the Chilterns demands. We have been featured in Dezeen, Grand Designs Magazine and The Modern House Journal, and in 2025 I was invited to judge the British Homes Awards — a recognition of the breadth of our experience across conservation, sustainability and new design.
Architectural Services for Homes in Askett and Whiteleaf
Renovations in Askett and Whiteleaf demand a sensitivity to materials that have been shaped by centuries of local tradition. Askett's conservation area, designated in 1977, protects a village core where Chiltern brick, knapped flint, thatch and timber framing sit alongside one another — sometimes within the same building. Among the fourteen listed buildings here you find structures dating from the seventeenth century onwards, each one a record of how this place has been built and rebuilt over time. Whiteleaf, too, has its own conservation area, with properties along the Upper Icknield Way that include some of the oldest dwellings in the parish. Working with buildings like these requires patience and knowledge in equal measure. My training with the Society for the Protection of Ancient Buildings shapes every renovation we undertake — a philosophy of careful repair, working with what exists rather than imposing something new.
Paragraph 84 of the National Planning Policy Framework creates an exceptional route for new homes in the open countryside, provided the design is truly outstanding and sensitive to its setting. The agricultural land and beechwood slopes of the Chilterns National Landscape around Askett and Whiteleaf set a high bar for any new dwelling. A Paragraph 84 home here would need to respond to the contours of the escarpment, the patterns of hedgerow and field boundary, and the material traditions — flint, brick, timber — that connect these hamlets to their surroundings. This is design at its most site-specific, and it is work we find deeply rewarding.
EnerPHit offers a pathway to Passivhaus-level energy performance for existing buildings, and many of the older homes in Askett and Whiteleaf stand to benefit significantly. Solid-walled cottages built when energy was cheap carry heating costs that no longer make sense. EnerPHit addresses this through breathable insulation systems, high-performance glazing carefully scaled to existing window proportions, and airtightness improvements that work with rather than against historic building fabric. In conservation areas where external changes are closely assessed by Buckinghamshire Council, much of this work happens internally — which suits both the planning context and the buildings themselves.
Sustainable Design is the thread that runs through everything we do. We design homes that are more comfortable to inhabit, more economical to run and more joyful to live in — not in spite of their setting but because of it. In a landscape where buildings have always drawn on local materials, sustainability is not an imported idea but a continuation of an existing tradition.
Extension Design for homes in Askett and Whiteleaf means working within the expectations of Buckinghamshire Council and the constraints of two conservation areas. Any addition needs to respect the scale, materials and character of the existing building and its neighbours. We see these constraints as creative opportunities — the best extensions feel like they have always been part of the building they serve.
New Build Design and PassivHaus Design apply where new homes are proposed in or around these hamlets. The Deerings, our RIBA award-winning Passivhaus home, demonstrated that the highest standards of energy performance and genuine architectural quality are natural partners. Any new dwelling here should sit comfortably within the Chilterns landscape, drawing on the material palette and sense of place that give Askett and Whiteleaf their character.
Askett and Whiteleaf sit where geology becomes architecture — where the chalk, the flint and the clay have been turned into walls, roofs and boundaries by generations of hands. That relationship between ground and building is something we care about deeply. If you are considering a renovation, an extension, or a new home in either hamlet, we would welcome the conversation.
