Common questions
Direct, plain answers. No marketing copy.
How much does a loft conversion cost?
A dormer conversion typically lands between £45k and £80k including drawings, build and an en-suite. Mansard and hip-to-gable are usually more — £60k–£110k. Use the Project Cost Tool for a postcode-adjusted range.
Will I need party-wall agreements?
If you share walls with neighbours (typical of terraced and semi-detached), yes. The Party Wall etc. Act 1996 sets out the process — most loft specialists handle the paperwork as part of pre-build.
How long does a loft conversion take?
Dormer conversions typically take 8–12 weeks on site. Mansard and hip-to-gable run 10–16 weeks. Add 6–10 weeks for design and planning before work begins.
