Listed Private House
Trenarth is a fine listed granite farmhouse with outbuildings and ground of matching quality.
The front elevation however had been masked by a neo-classical sunroom/conservatory of generous proportion being 16.5 m x 4.30 m. The predominantly flat, asphalted roof has been leaking for many years and it is suffering severe decay to the timber structure.
It was our client's proposal to demolish it entirely, thus revealing the ground floor entrance and windows and greatly enhancing the main southwest elevation. It was proposed to provide a new extension at right angles to the façade, which will use the existing stone garden retaining wall as the back wall. This wall was unstable and required re-building. It had been inspected by a structural engineer who proposed a new concrete retaining wall behind the rebuilt stonework.
The new building has been roofed in natural slate reclaimed in the part from outbuildings at Trenarth. Its ridge level is immediately below the granite stringcourse of the house.
The southeast elevation has been fully glazed in painted hardwood frames with one pair of French doors.
The southwest elevation has a half height natural stonewall with a slate cill and glazing over.
The fascias are painted softwood with cast iron ogee gutters and rainwater pipes.
It was felt that this proposal would be significantly less intrusive and would neatly link the dwelling to the garden.
Since the access to the existing structure through the main doorway would no longer be available to the new building it was proposed to form a new doorway through the dining room wall, again this proposal had been considered and appraised by the structural engineer. It was proposed to replicate the existing dining room door and architraves for the new opening, thus minimising the effect upon the interior of the house.
