This document discusses a case study of renovating an old cottage in the Lake District to make it more sustainable and efficient. The renovation involved external wall insulation, new highly insulated roofing, and an upgraded heating system. A modular extension was also added with factory-built, highly insulated walls and underfloor heating powered by an air source heat pump and solar panels. The renovation seamlessly blended traditional and modern construction methods while fully integrating renewable technologies to provide a comfortable, efficient home for years to come. The future holds improved building regulations and more efficient buildings that are less reliant on fossil fuels through better integration of renewable options based on a building's specific characteristics.
