The Belgravia Group

The Belgravia Group is a premier windows and doors company dedicated to enhancing your living spaces with modern elegance and unparalleled craftsmanship. Our story began in 2011 when Mariusz and his wife Justyna founded a building and construction company that has since evolved into the dynamic enterprise you see today. With over 20 years of industry experience, Mariusz has a deep-rooted passion for construction and glazing. As demand for our services grew, we opened a joinery in London, specialising in timber-framed glazing. To meet increasing demand, we moved our timber window and door fabrication to a workshop near the German border in Poland, where each piece is handmade with precision and care
