Gransden Construction is carefully transforming a set of time-worn stable outbuildings into high-quality ancillary space for modern domestic use—retaining the courtyard character while giving the buildings a long-term future. The project reuses the former stables as a gym/office/study with storage, complemented by a rebuilt lean-to providing additional storage and a small cloakroom.
What we’re building
- Structural stabilisation: selective underpinning to retained masonry; rebuilding sections of the south and west walls on new foundations using reclaimed/matching brickwork.
- New roof & structure: complete roof rebuild with four new oak trusses.
- Envelope upgrades: west/front elevation replaced with oak-framed glazing and doors; conservation rooflights to the rear elevation.
- Lean-to replacement: new timber-framed lean-to on brick plinth with black metal sheet cladding to roof and walls and aluminium windows/door.
- Internal works: insulated concrete floors, repointing to retained brickwork, wood-fibre insulation with breathable plaster to internal faces.
Working with historic fabric
The design intent is to repair and re-use the outbuildings so their setting and aesthetic value are preserved—maintaining the established courtyard grouping and materials palette while providing a viable contemporary use.

Collaboration & team
We’re pleased to be working closely with J.N. Atelier Design Ltd, aligning workmanship samples, details and sequencing with the design intent to protect the building’s character while improving performance.
