Heritage Barn Transformation

This project centred around a rare cob‑built agricultural building with a long and layered history. Although its exact construction date isn’t recorded, the structure is believed to originate from the Georgian period, later adapted repeatedly as farming needs changed — from water conduit to grain silo in the mid‑20th century, with stables added around 1860. It is a textbook example of a rural working building shaped by incremental change, and our task was to stabilise, preserve and carefully transform it into a home without erasing the story embedded in its fabric.

Cob construction demands a fundamentally different approach to conventional masonry. The walls are thick, breathable and highly dependent on their original geometry for strength; once disturbed, they become vulnerable to shear, collapse and moisture imbalance. Before any new work could be considered, we undertook a detailed assessment of the building’s behaviour, identifying areas of movement, erosion and historic patch repairs. This informed a programme of stabilisation and consolidation designed to re-establish continuity in the cob and ensure it could safely carry new loads. Every intervention required judgement — balancing what to retain, what to rebuild and how to reinforce without compromising authenticity.

One of the most technically demanding operations was lifting the entire roof structure clear of the cob walls — a task made more complex by the scale of the building, the fragility of the material and the consequences of even minor movement. Cob does not tolerate point‑loading or sudden shifts, which would have led to the collapsing of historic, longstanding walls, so the temporary works had to be engineered with extreme care, distributing weight evenly and maintaining stability throughout the lift. Working within tight spatial constraints and with a structure that had already experienced historic deformation, every stage required controlled sequencing, continuous monitoring and the ability to respond immediately to changes in the building’s behaviour. The operation was not simply a logistical challenge but a high‑risk intervention where the safety of the historic fabric depended on precise judgement and disciplined execution.

With the roof supported and the cob stabilised, we were able to extend, restore and repair the building using compatible, breathable materials — lime mortars, traditional plasters and reclaimed elements wherever possible. Original openings, proportions and key features were retained or reinstated, while new interventions were detailed with restraint so they sit quietly alongside the historic structure. The aim was always to strengthen the building without overwhelming it, allowing its agricultural character to remain legible. All in all, the success is present in the building that stands today, a forever home.

The result is a building that still reads clearly as the working barn it once was — its massing, texture and presence intact — but now performs as a warm, durable home designed for modern living. The transformation was not simply a conversion but a careful technical exercise in understanding, stabilising and extending a fragile historic structure. The building’s future now rests on a foundation of informed decisions, precise workmanship and a deep respect for the material that has held it together for centuries.
