Glazed Home Extensions Northampton, Corby & Kettering

This glazed style extension dates back to the 17th century. Back then solid brick walls with windows were used to retain as much heat as possible, with glass roofs allowing natural light to flood in. At T&K, we offer this adapted classic design around Northampton, Corby and Kettering. It combines the needs of modern living with high security PVC-U windows and doors. They also carry the highest energy efficiency ratings.
