Building FAQ
Do you handle planning permission and building control?
We advise on permitted development limits and can liaise with architects and building control. We coordinate inspections at each structural stage.
How long does a typical extension take?
A single-storey rear extension usually takes 8-14 weeks depending on size, ground conditions, and finishing spec. We provide a programme after the site survey.
What deposit do you require?
We structure stage payments tied to completed milestones rather than large upfront deposits. Terms are set out clearly in your written quote.
Can you work while we live in the property?
Yes. Most of our domestic projects are completed with families in situ. We dust-sheet routes, maintain access, and clean down daily.
Are you insured for structural building work?
Yes. We hold public liability and employers liability insurance. Certificates are available on request before work commences.
