Common Questions

Details regarding our process, planning constraints, and project timelines.

Many single-storey extensions and loft conversions fall under Permitted Development rights. However, larger extensions, properties in conservation areas, or flats will require full planning permission. We assist with architectural drawings and planning applications as part of our comprehensive service.
A standard single-storey rear extension typically takes 10-14 weeks from breaking ground to final handover. Complex double-storey extensions or projects requiring significant structural steelwork may take 16-24 weeks. We provide a detailed timeline prior to contract signing.
Yes. We carry comprehensive public liability and employer's liability insurance. All structural work is guaranteed, and we work alongside independent Building Control inspectors to ensure all work meets or exceeds UK Building Regulations.
We use a transparent, staged payment structure. Payments are tied to specific, verifiable project milestones (e.g., groundworks complete, steel installed, watertight). You only pay for work that has been completed and signed off.
