HAL were commissioned to produce Building Regulations drawings for a ground-floor and basement extension to this Grade II listed building.

Careful attention to detail was essential. The brickwork was laid in Flemish bond with lime mortar, and the roof finished in slate with a feature roof lantern. The basement was built using a concrete-filled retaining wall system, with tanking provided by a cavity drained membrane system (all specified by specialists) to ensure a dry and durable space.
