Specialist engineering for side-return, rear, and rooftop extensions on Lambeth's Victorian and Edwardian properties.
Structural Design for Home Extensions in Lambeth
We are experts in the structural design of home extensions, the most common type of residential project in Lambeth. From classic side-return extensions on Brixton's terraces to larger wrap-around additions in Streatham, our designs provide efficient and buildable solutions. We focus on optimising internal space by minimising the structural footprint.
Local Challenges
Home Extensions in Lambeth
Lambeth's Planning Policy Q26 and the Residential Extensions and Alterations SPD place clear limits on the depth, width, and height of extensions, especially in conservation areas. Our structural designs work within these constraints, often using concealed steelwork or goalpost frames to create wide openings to the garden without visually intrusive columns. We also manage the complexities of building on or near the party wall line.
