Two Storey Extension to a Stone Cottage

The project is the extension and refurbishment of a stone walled cottage to provide a large family kitchen and an extra bedroom with ensuite bathroom.

The extension uses matching stonework to face the entrance elevation and the end and internal side are finished in lime based render. The facings are on to an insulated blockwork cavity wall but with the conventional arrangement of the blockwork leaves reversed with the insulating blockwork to the outer position and the dense concrete blockwork internally to provide a high thermal mass internally wrapped in insulation which helps to provide more even internal temperatures in both winter and summer. The cavity and roof insulation are both in excess of that required to meet the Building Regulation minimum. High performance double glazed windows and external doors together with a slate roof to match the existing complete the building exterior.

Early reports after occupation indicate that the thermal strategy is acting well with only the electric range cooker (“Aga” equivalent) coping well with the heating required in the kitchen during the coldest months.
