Jeshilt Cottage

From the outset DMW worked closely with LJ Harvey (structural engineers), who determined that the original building was structurally unsound and not suitable for renovation, extension or conversion. Following close consultation with Dorset Council and The National Trust, the decision was made to construct a new, thermally efficient replacement dwelling that would faithfully replicate the original cottage with later additions juxtaposed to this. 

An key consideration of the design was how the existing building had high visual importance when viewed from immediate and broader context. The existing building had extremely low floor to ceiling heights and the new proposal needed to increase these. As a result, the final scheme maintains all the external characteristics of the existing whilst providing internal spaces that are light, bright and well-scaled. 

The thatched reed roof—a defining characteristic of the region—was reintroduced not only as an aesthetic marker but as a high-performance thermal insulator sourced from sustainable local suppliers. English oak cladding and natural slate contribute to a durable, low-maintenance envelope with a minimal embodied carbon footprint, ensuring longevity and resilience against the elements.

The building’s thermal envelope incorporates high-performance insulation and airtight detailing, significantly reducing energy consumption. The inclusion of large-format glazing in the rear extension not only maximises natural light but fosters passive solar gain, reducing the need for mechanical heating.
