Bath & North East Somerset Council (BANES) commissioned essential external repairs to the Grade II listed townhouse within Bath’s historic conservation area, under their General Maintenance Framework. With responsibility for one of the largest heritage property portfolios in the country, BANES carefully invests in projects like this to protect and maintain the historic assets in their care.

Client Requirements

Dating back to 1762, the townhouse required careful restoration of its Mansard roof detailing, roof skylights, and traditional timber-framed sash windows to preserve its historic fabric and maintain the architectural integrity of the listed building. Over time, these elements had deteriorated due to weathering, age, and wear, making repairs essential to prevent further damage and maintain structural stability. This meant that specialist heritage expertise was needed to carry out the repairs without compromising the building and its original features.

How we Helped

BANES’ Conservation team and Planning department were brought into the project early, creating a shared framework for approvals, compliance, and programme planning. This collaborative approach allowed the works to be shaped sensitively, respecting both the building’s character and the surrounding environment.

With the strategy aligned, our specialists carried out a detailed survey of the structure, examining the historic fabric and identifying the nuances that guide responsible conservation. These findings informed tailored method statements and risk assessments, setting out a clear, safe, and respectful approach to each element of the works. Our heritage-trained operatives then delivered the programme with precision - every intervention carefully measured, every action grounded in conservation best practice, and every stage completed safely and accurately.

Key measures we implemented included:

  • Repaired the Mansard roof to restore detailing and strengthen the structure
  • Refurbished roof skylights: two 12’ x 12’ units at the front and one 1m x 3m unit at the rear
  • Restored timber-framed sash windows, preserving original design
  • Installed internal crash decks (10–12’ high) to safely replace glazing and timber elements, including Georgian wired glass
  • Carefully planned the works to minimise disruption and ensure compliance with listed building requirements

Project Outcome
The refurbishment has safeguarded the character and historic integrity of this Grade II listed townhouse, ensuring it remains functional and protected for the future, while enhancing its architectural details and reinforcing its long-term durability.
