Local Challenges
Loft Conversions in Barnet
A key challenge in Barnet's housing stock, particularly the 1920s and 30s properties, is that existing roof structures were not designed to support a habitable floor. Our work involves designing new floor joists and steel beams to transfer the new loads safely down to the property's foundations. We also address potential planning constraints on the size and appearance of dormers, particularly in conservation areas, by providing efficient structural schemes that work within the architect's approved design.

Recent Project
Mill Hill, Barnet
For a semi-detached property, we designed the structure for a hip-to-gable and rear dormer loft conversion. This created a large master bedroom and en-suite. The design involved a key steel ridge beam and careful detailing to maximise headroom over the new staircase.
