Restoration at the Grade I Listed Museum of Farnham, undertaken on behalf of Waverley Borough Council, is well underway, revealing some fascinating discoveries.
Simpson Brickwork Conservation has completed a detailed measured survey and recorded the original construction of the parapet wall. Several moulded brick samples have been retained to facilitate the production of new hand-cut bricks for the restoration.
The careful dismantling of the parapet wall has now been completed, leading the team to now believe that the parapet wall is not original, as the external gauged brick face was not physically tied to the main parapet wall brickwork.
Restoration specialists have begun developing new mortar for the repair of gauged brickwork. The mortar mixture is being refined, but the final blend will likely consist of lime putty, high-quality well-graded buff-coloured sharp sand, and crushed Bath Stone aggregate.
The facade survey is nearly complete, revealing that the brickwork’s condition is generally as expected. However, deterioration is evident in the gauged brick window architraves and cills, with significant decay in the mortar joints. While facade cleaning has removed a considerable amount of deteriorated mortar, additional joint refilling will be necessary.
The sash windows have sincerely impressed us all. Dating back to the 1700’s, these windows remain a remarkable feature of the building, with nearly all retaining their original handmade glass. Despite their highly vulnerable condition, all windows are fully repairable.
The whole team remains dedicated to maintaining the integrity and authenticity of this remarkable historic building, whilst ensuring its longevity for future generations.
