“Aspect builders are a very professional, personable team. We used them to create our vegetable garden and had significant kitchen structural work carried out. Both projects were completed to an excellent standard. Highly recommend.”
“The team has done a lot of work for us including designing and fitting a new kitchen and putting in a new bathroom. They are extremely helpful, very tidy and the work is to a very high standard. We would not hesitate to recommend them.”

Frequently Asked Questions
How much does a loft conversion cost in Bath?
Costs vary widely depending on the type of conversion (Velux, dormer, hip-to-gable, mansard), size, structural work, and finish level. We give you a fixed-price quote after a free site visit, so you know the exact cost before any work starts. No day rates, no open-ended estimates.
How long does a loft conversion take in Bath?
Velux conversion: 4-6 weeks. Dormer conversion: 6-10 weeks. Hip-to-gable: 8-12 weeks. Mansard: 10-14 weeks. We provide a detailed programme at quote stage and stick to it.
Do I need planning permission for a loft conversion in Bath?
Most Velux conversions fall under Permitted Development. Dormer and hip-to-gable usually need planning permission, especially in Bath's conservation area. We check and handle the full application if needed — typically 8 weeks lead time.
Can you do hip-to-gable loft conversions in Bath?
Yes — hip-to-gable is a core part of our loft conversion work. We work on semi-detached and detached houses across Bath. Structural calculations, building regulations, party wall agreements — all managed in-house.
Can you build a dormer loft conversion in Bath?
Yes — rear dormers, side dormers, and L-shaped dormers are all part of our work. We handle the structural work, the dormer construction, the windows, and the internal fit-out.
Can you do a loft conversion on a listed building in Bath?
Yes — heritage and listed-building loft conversions are part of our work. Conservation-officer liaison, traditional materials, sympathetic detailing. Work that respects the building's heritage and meets Bath conservation requirements.
Will I be able to live in my home during the loft conversion?
Yes — most loft conversions are done with the home occupied. We isolate the work area, dust-sheet, clean daily, and respect your space. Typical disruption is 4-6 weeks of noise and dust during the structural phase.
Are you insured and qualified to do loft conversion work in Bath?
£10M+ public liability (AXA-verified). CSCS cardholders, City & Guilds / NVQ qualified. James is MCIOB chartered through the Chartered Institute of Building. All documentation on request.
