Croydon

Hip-to-Gable Loft Conversion specialists across Croydon.

We deliver hip-to-gable loft conversion projects across the full Croydon postcode set — CR0, CR2, CR5, CR7, CR8, CR9, SE25. South London borough with strong appetite for lofts, extensions and garage conversions.

A hip-to-gable converts the sloping hip on the side of a semi-detached or end-of-terrace house into a vertical brick gable wall. This rebuilds the roof footprint into a simple pitched form that mirrors a mid-terrace, and almost always pairs with a rear dormer to deliver a master suite, two bedrooms, or a bedroom-plus-office layout with full headroom across both. It's the highest-value loft conversion for 1930s and 1950s London semis — the kind that line streets across Barnet, Enfield, Bromley, Croydon, Sutton, Harrow and Ealing.

Every Croydon project includes a free desk-based planning assessment before we quote. We know the local planning officers, party wall surveyors and approved inspectors by name.
