As premier builders in Kingston upon Thames, DM Spragg Ltd specializes in high-value house extensions and structural alterations. Adding an extension is one of the most effective ways to increase the market value of your property in Surrey while creating the open-plan living space modern families desire.
Our team manages the entire lifecycle of a loft conversion. From the initial steel beam installation to the final insulation and plastering, we ensure compliance with UK Building Regulations. Whether it’s a dormer conversion, mansard, or hip-to-gable, utilizing your roof space is a sustainable way to add bedrooms and bathrooms without eating into your garden space.
We coordinate with architects and structural engineers to ensure that every load-bearing wall removal or RSJ installation is executed with precision safety standards.
