We provide the essential structural engineering for house extensions throughout Merton. Our service delivers the detailed calculations and drawings required for Building Control approval, ensuring your project is safe, compliant, and buildable. We specialise in the structural challenges posed by Merton's housing stock, from designing box frames for side-return extensions on terraced houses in Colliers Wood to specifying foundations for larger extensions on detached homes in Wimbledon.
Local Challenges
House Extensions in Merton
A key challenge for extensions in Merton is respecting the character of the existing property and the surrounding area. For terraced houses, this involves careful consideration of party walls and ensuring new foundations do not compromise neighbouring structures. Merton's planning guidance is also specific about overlooking and loss of light, often referencing the '45-degree rule', which can influence the structural form. Our designs account for these local constraints, providing solutions that are both structurally sound and sensitive to the planning context.
