Project Description:

An historic watermill project with a continuous history stretching back to 1535, and records as early as 1302. Converted from a grist mill to a papermill in the 18th Century, and subsequently converted to a house in the 1960's, it became home to a well regarded prisoner of war artist who converted the former paper drying loft into an artists studio.   

This sizeable building had fallen into disrepair with a precarious roof structure and unstable walls, and required significant investment to safeguard its future. Our involvement with the project commenced in 2019 with the new owners following approval to partially rebuild the rear section of the building along with an orangery extension. The programme of works consisted of a total refurbishment throughout including structural stabilisation, mortar repairs and a complete new roof. 


ArchiWest worked closely with the structural engineer to develop the stabilisation strategy, roof details, steel ridge beams, and vaulted ceilings. The roof was stripped back, timbers repaired and reclaimed double roman tiles installed.            

The building had been cement rendered throughout, trapping moisture within the thick stone walls and slowly deteriorating the building fabric. This was carefully removed to expose the natural stonework, and repointed with a soft lime mortar, slaked on site. The walls were lined internally with breathable insulation to significantly improve the U-values.

Turbine - One very unique aspect to this project also included the restoration of a 1950's turbine and hydroelectric plant. When fully operational this will provide sustainable energy harnessed from the mill stream to run the entire house.
