Questions we get asked a lot

Yes. We visit, look at the roof or garden space, talk through what you want and send a fixed-price quote. There's no obligation.

It depends on the roof shape, head height and planning rules. Terraces usually suit a rear dormer, semis often suit hip-to-gable plus dormer, and period terraces in conservation areas may suit a mansard. We advise at the survey.

Yes, and it often saves money because drawings, approvals, scaffolding and site setup are shared. Use the price calculator to see both together.

Many lofts and single-storey rear extensions in England can be built under permitted development. Flats, maisonettes, conservation areas, Article 4 areas and larger projects usually need planning. We check your address and handle the application if needed.

Every loft conversion and extension needs building regulations approval, covering structure, fire safety, insulation and stairs. We apply, arrange the inspections and hand you the completion certificate.

If you share a wall with a neighbour, the Party Wall etc. Act 1996 usually applies to lofts and many extensions. We prepare and serve the notices.

Your quote is itemised. It lists exactly what's included, typically drawings, structural calculations, building control, materials, labour, scaffolding and waste removal, and what isn't, such as decorating, kitchens or flooring.

We agree a staged payment schedule in writing before work starts. Payments are linked to clear milestones in the build, with the final payment after sign-off.

Only if you change the specification, or if something hidden is found that we couldn't reasonably see at survey. If that happens, we agree any change with you in writing before doing the work.

For most loft conversions, yes: much of the work happens from the scaffold until the stairs go in. With extensions you'll usually lose use of the kitchen for part of the build, and we'll help you plan for that.

Once drawings and approvals are in place, a typical loft conversion takes 6–10 weeks on site and a single-storey extension 8–12 weeks. You'll get a written programme before we start.

Usually Monday to Friday 8:00–17:00, in line with local council guidance on noisy work.

Every project is signed off by building control, and we put right any defects in our workmanship. The terms of our guarantee are set out in your contract.

The building control completion certificate, electrical certificates, your guarantee and any planning documents. Keep them safe; you'll need them when you sell.
