Extension Builder in Merton Park
I have had the privilege of working on a 260-year-old Grade Listed building in Islington, London, under the close supervision of conservation inspectors. This project required a careful balance of tradition and innovation — I combined the use of modern machinery externally with traditional, delicate methods internally to ensure the building remained completely scratch-free. My experience has given me a deep respect for heritage projects as well as the skills to deliver high-quality results on modern refurbishments.
