Senior Structural Specialist
"I oversee all loft conversions in the Southend-on-Sea 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.
