Senior Structural Specialist
"I oversee all loft conversions in the March area. My job is to ensure your project meets local building regulations while maximizing every inch of space. I'm happy to visit your property for a preliminary structural assessment."
Four recent loft conversions across the UK — from a London mansard within a conservation area to an L-shaped Manchester dormer, a Birmingham hip-to-gable, and a Leeds rear dormer. Tap any project for the full case study.
Loft
Mansard loft conversion on a London Victorian terrace within a conservation area — full mansard build raising the rear roof line, slate-clad cheeks to match the neighbours, two double bedrooms with private en-suites, and a sky-lit landing. Approval secured under full planning, not Permitted Development.
Loft
L-shaped rear dormer loft conversion on a Victorian terrace — turning unused roof space into two double bedrooms and a shared en-suite, with two Velux windows to the front, a glass balustrade to the new staircase, and matching slate-grey finish to blend with the original roof.
Loft
Rear dormer loft conversion turning unused roof space into a master bedroom and en-suite, with two Velux roof windows to the front and a slim glass balustrade to the new staircase.
Loft
Hip-to-gable conversion with rear dormer on a 1930s semi-detached — squaring off the original hipped roofline to gain full standing headroom, creating a master bedroom with built-in wardrobes and a generous en-suite, plus a third Velux to the front for natural light.
