The project brief was to extend an existing stone Victorian ‘villa’ in rural Lothersdale, Yorkshire. This is detailed in two parts, in both a vernacular dressed stonework extension (built sustainably from re-purposed stone salvaged from demolished out-buildings, garden walls and patios from the site), contrasting with a far more contemporary-looking, ashlar limestone-clad and glazed-wall swimming pool. The new pool is dug into the existing sloped hillside garden and set within a relaid terraced lawn, with dry stone retaining walls and a limestone ‘scree-bed’ surround. The new building sits within a refurbished kitchen walled garden, complete with re-built stone shed with attached new cedar greenhouse. Pool and space heating is by an Air Source Heat Pump, with electric boosted by a roof-mounted PV solar system – complete with powervault battery storage inside.
