Longton Farmhouse sits within the conservation area of a quintessential Oxfordshire village, where coursed rubble limestone cottages sit alongside 16th-century manor houses and the Grade I-listed village church.

Works began with the removal of a failing conservatory and the subsequent build of a carefully considered glass and zinc extension. Sensitive in scale, mass, form and materials, the new structure takes its cues from the old stone farmhouse and its surrounding conservation area.

“Modern in design yet discreet and sensitive in scale, appearance and materials, the new extension design takes its cues from the surrounding conservation area.”

Bethan Axford, Architect, Thinking Buildings
In brief

Characterised by a tapered, bronze-coloured over-sailing zinc roof, which floats above minimally framed glazing, framing and highlighting the property's distinctive elongated façade.

Our clients’ ambition was to improve the quality and appearance of the farmhouse through the reimagining of the central section of the property, where an out-of-place conservatory was in a state of disrepair, resulting in poor energy performance and limiting year-round use due to temperature extremes.  

Works centred around the construction of a considered modern extension, designed to transform the central living space and improve the property's energy efficiency, whilst enhancing its original structure and form.  

The extension is ‘light in form’, allowing the old stone walls to take centre stage. Inside, a cohesive open-plan living and dining space was enabled by means of an enlarged opening in the rear stone wall. The extension connects through from the old kitchen to the rear gardens, drawing natural light into the centre of the property.  

Considered construction methodology included skilled stonemasonry and metalwork, as well as careful airtightness and insulation optimisation, which has transformed the liveability and energy efficiency of the property.  

Structural Harmony

The extension achieves a purposeful distinction between the old and new architecture: modern in design yet discreet and sensitive in scale, appearance and materials.

Energy efficiency

The extension was designed using a fabric-first approach, with deep insulation, excellent airtightness and high-performance glazing.  


Floating roofline

A barely sloping, standing-seam Zinc roof floats over the minimal glazing, creating a sleek horizontal roofline which emphasises the property's elongated old stone façade.  


Minimal framing

Fineline floor-to-ceiling glazing and a slim-profile zinc roof serve to highlight the carefully revealed stone walls of the original farmhouse.  


Light and depth

A glazed rooflight brings natural light deep into the property, compensating for minimal openings on its road-facing north side.  

“Our extension, designed by Thinking Buildings and delivered by Barr Build, has completely changed the way we use our home. The old conservatory was too hot in the summer and too cold in the winter, significantly limiting its use. Now, the centre of our home is bright, energy efficient and comfortable year-round.”
