Two Storey Extension – Watford, Hertfordshire
This Watford home has been transformed with a large two-storey rear extension, creating additional living space across two floors, enhancing both functionality and property value. The project also included internal alterations and a part garage conversion, allowing the homeowners to make the most of their available space while ensuring the structure remained safe, stable, and compliant with Building Control.
To bring this ambitious project to life, PorthouseDean provided expert structural calculations, supporting the structural framework, steel beam reinforcements, and load-bearing wall modifications. The project was successfully delivered in partnership with Detailed Planning architects.
