Basingstoke loft projects

Basingstoke has a high proportion of 1960s–1980s detached and semi-detached houses with hip roofs — common in estates across Chineham, Popley, South Ham and Oakridge. These often suit a hip-to-gable conversion combined with a rear dormer to maximise usable floor area. Detached properties may also suit a large L-shaped dormer. Velux-style conversions are possible where head height is already adequate and planning restrictions preclude dormers.

Many loft conversions in Basingstoke can be built under Permitted Development Rights without a formal planning application — provided the volume addition is within permitted limits (40m³ for semi-detached/terraced, 50m³ for detached) and the dormers don't face the principal elevation. However, Basingstoke and Deane Borough Council has conservation areas in parts of the town and surrounding villages where full planning permission is required. We check your PD status during every complimentary consultation.

Our fixed design fees are: Pre-Build Package from £1,950 + VAT (planning drawings and/or building regs drawings) and Premium Plus from £4,950 + VAT (full service). Build costs for Basingstoke loft conversions — paid to your contractor — typically run £35,000–£65,000 depending on the conversion type and finish level. Dormer conversions cost more than Velux-only; full hip-to-gable conversions are at the higher end.

If your loft conversion qualifies under PD (no planning permission needed), building regulations is the main approval required — typically 6–8 weeks for a full plans application. If planning permission is needed, Basingstoke and Deane Borough Council targets an 8-week determination period. We can run both approvals simultaneously to minimise total time before you can start on site.

Yes — semi-detached loft conversions are one of our most common Basingstoke project types. They typically involve a rear dormer, hip-to-gable conversion, or both. For semi-detached properties, the party wall between you and your neighbour runs through the shared roof, meaning a Party Wall Award is usually required before work begins. We can advise on party wall obligations during your complimentary consultation.
