Local Challenges

Loft Conversions in Merton

The primary structural challenge in Merton's housing stock is adapting the existing roof structure. For the common 1930s hipped roofs in Morden, a hip-to-gable conversion is often required, involving significant structural alterations. In Victorian terraces, the roof pitch and internal structure dictate the feasibility and design of dormers. Our role is to design an efficient and strong new structure that supports the new loads and integrates with the existing house, ensuring long-term stability.
