Castle Ashby Estate Office

Location: Northamptonshire

Client: Private Client

Architect: Freeland Rees Roberts

Value: £1.2M

Castle Ashby Estate Office occupies an 18th-century former coach house and is a Grade II listed building.

Following a severe fire, the project involved repairing and reinstating the historic structure while improving its function as a modern workplace. The scheme combined careful conservation of surviving fabric with a reorganisation of the internal office accommodation.

The fire destroyed almost the entire roof and much of the first-floor structure, leaving only the external masonry walls, parts of the gables, some internal partitions and a small number of original oak truss elements. The tops of the walls required rebuilding, internal steelwork had been damaged, and the retained cast iron columns needed repair. The reinstated building also had to meet current fire and access requirements. 

SFK developed a structural repair strategy that combined conservation-led reinstatement with new structural interventions.

Damaged stone walls and gables were rebuilt, internal steelwork was replaced, and surviving cast iron columns were repaired and retained. The lost roof was reformed using new green oak trusses, detailed to replicate the original structure with traditional joints, while also being designed to support the new first-floor estate office loading.

The project successfully restored the listed building and returned it to active use as a high-quality estate office.

The rebuilt roof and repaired masonry reinstated the historic character of the former coach house, while the reorganised internal layout provided improved office accommodation across both floors. The scheme preserved significant original fabric where possible and delivered a robust structure suited to its ongoing operational use.
