Stone barrelled vault converted to workshop and playroom
in Somerset

Beneath a large country manor house in Somerset stood a damp, dark and dingy stone barrelled vault measuring 13 x 6 meters.


The contractor was contacted by the owner to see if it would be practical to convert this unusable area into a workshop and playroom. Following a survey and establishing the needs of the client a proposal was put forward to provide a 'Type C' drained waterproofing system in accordance with BS 8102.


The floor, walls and the ceiling of the vault were lined with a cavity drainage membrane and WaterGuard drainage was introduced around the perimeter of the existing concrete floor, discharging to an existing floor drain in the adjoining wine store. The floor area was then over laid with 22mm moisture resistant chipboard and studding formed all round, walls plaster boarded and rough skimmed.


In conjunction with the main waterproofing works two mechanical 'positive pressure' ventilation systems were installed to improve air quality as no passive ventilation existed.


Having completed the works the client then decided to split the area into two and a central timber framed wall was introduced to form two distinct areas. 


With the improved lighting and the introduction of heating the client, a keen picture framer, now has a clean, dry and warm workshop whilst his children have a bright and spacious playroom.
