Structural Design for Basements in Merton
We are specialists in the structural design of new and extended residential basements in Merton. Our work is critical for satisfying the borough's rigorous planning and building control requirements.

Local Challenges
Basement Conversions in Merton
Merton Council has a specific and detailed policy for basement developments (Policy DME4), making it a significant planning hurdle. The key challenges are managing groundwater, ensuring the stability of the host property and its neighbours, and minimising construction disruption. Our structural designs directly address these issues. We design robust underpinning sequences and temporary works, specify appropriate waterproofing systems, and provide the technical documentation required to demonstrate to planners and building control that the project is feasible and safe.
