Frequently Asked Questions

Many single-storey rear extensions and certain loft conversions fall under Permitted Development. Rules depend on size, height, materials, and location. We’ll assess your property, advise the best route and guide you through the process.
Timescales vary by scope and permissions. As a guide: design and cost planning (2–6 weeks), planning or lawful development sign-off (6–10+ weeks, authority-dependent), technical design and procurement (2–4 weeks), and construction - smaller kitchen/ground-floor extensions (10–16+ weeks), larger two-storey or major refurbishments (16–28+ weeks). You’ll receive a detailed programme before we start and regular progress updates throughout.
Absolutely. We frequently collaborate with clients architects and interior designers, or we can introduce trusted partners. We integrate their drawings into our programme, coordinate structural engineers and specialists, and remain your single point of contact. Where appropriate, we suggest improvements and value-engineering options without compromising the design intent.
We provide an itemised, transparent quotation aligned to the agreed drawings and specification, with any Provisional Sums clearly identified. Sensible contingencies are discussed upfront. Changes are priced and approved as written variations before work proceeds. You’ll receive regular cost reports alongside the build programme for complete visibility.
Often, yes, especially for kitchens, bathrooms and internal refurbishments - using careful phasing, dust protection, and temporary services. For larger extensions or structural works, short periods away can reduce disruption and shorten the programme.
