Restoration and repair to the roof of the residential castle formerly owned by Edwin Lutyens

The project focused on repair and sought to make additions and improvements that were sympathetic to the original building.

The key to the castle's decay was found in the roofing, commissioned by the then owner, Edwin Lutyens, in 1910. His was a 'cold' roofscape of granite paving slabs which sought unity with the walls, and an overall impression of geological permanence.

The roof design, however, did not allow for insulation, ventilation or thermal movement. Consequently, substantial mould growth and water permeation was discovered in the construction, as well as a lime precipitate on the exterior stonework.

Inskip and Jenkins implemented modern roof technology: a warm deck roof and a waterproofing membrane, to ensure the longevity of their construction. The castle's U shape construction caused this to be a lengthy process.
