Expert structural engineering for basement conversions and new-build basements across the London Borough of Southwark.
Basement Structural Design
We provide specialist structural design for creating new habitable space beneath Southwark's period properties. Whether retrofitting a basement under a Victorian terrace in Camberwell or an Edwardian villa in Dulwich, our designs focus on structural integrity, waterproofing, and maximising internal space.
Local Challenges
Basements in Southwark
Southwark Council has specific planning policies governing basement development, frequently requiring a Basement Impact Assessment (BIA) to be submitted with the application. We provide the necessary structural input for these assessments. Our designs carefully consider the challenges of the London Clay substrate, high water tables in areas nearer the Thames like Rotherhithe, and the critical sequencing of temporary works to protect adjacent properties.
