Knapdale cottage is one of two terraced cottages set back from the road with a gable-to-road arrangement. The house is category C listed in 1989 and sits within the Crinan Canal Conservation area.
The project saw the existing sun room removed and replaced with a pitched roof, extension offset at the back of the site that is not seen from the road thus maintaining the cottage form while forming a sheltered sunny spot to sit at the rear of the house.
The new extension provides a modern, warm kitchen|living|dining space with an additional bedroom on the ground floor. The project also saw the improvement of the existing house with replacement windows, internal insulation to improve its thermal performance and new bathrooms. Aluminium clad timber windows were used to reduce maintenance and improve durability of the frames in this exposed and wet location.
The new extension reflects the form of the existing building and local typology with low eaves, a steep pitched red roof and rendered exterior.
