Thurso
Thurso, the northernmost town on the British mainland, is known for its dramatic coastline, traditional architecture, and peaceful way of life. With a mix of stone-built cottages, post-war homes, and rural properties throughout areas like Mount Pleasant and Pennyland, many households in Thurso can benefit from increased natural light and better ventilation. Velux roof windows and sun tunnels are an ideal solution—helping to brighten dark interiors, enhance airflow, and improve energy efficiency, especially in lofts and extensions.
