Situated around the perimeter of Charterhouse Square this commercial 18th century charterhouse owned property was in need of a full external refurbishment. 

Minerva Building Restoration Ltd were instructed to act as principal contractor to undertake this project. The scope of works entailed procuring highways licences from the local authorities which permitted full scaffolding to be provided to all 3no elevations. Along with the replacement of traditional natural welsh slates lead flashings/details were renewed. The original sash windows were completely overhauled and fully redecorated. 

The external brick elevations were cleaned using a sympathetic stem cleaning system (Doff) revealing many areas of defective pointing. 

These areas were chased out to allow replacement lime based pointing to be applied.
