What Homeowners Say

Real Projects. Real Results.

“We’d been confused about where to start for months. After one call with cKraft, it all clicked. The drawings were clear and planning went through without any issues.”

— Gloria R, Rear & Side Extension, Hertfordshire

“We weren’t sure if we’d get planning permission. cKraft assessed everything upfront, were completely straight with us, and the application sailed through. Worth every penny.”

— Kaushik A, Double-Storey Extension, Surrey

“Our kitchen and living room feel completely different now. cKraft really understood how we live as a family and the layout reflects that.”

— Iftikhar A, Rear Extension, Middlesex

Common Question

We’ll Help You Understand It All

Not always. Some extensions fall under Permitted Development. During your free consultation, we’ll assess your property and confirm whether planning permission is required.

Most extension drawings are completed within 1-2 weeks. Planning approval typically takes 6-8 weeks, depending on your local authority.

You’ll receive full planning drawings, building regulations drawings, and any required structural details, everything your builder and the council need.

Yes. We offer full Building Regulations drawings as a separate service, and our in-house structural team can provide all required structural calculations. Everything is coordinated for you, so you don’t need to source anyone yourself.

We review your ideas, assess feasibility, explain the process, and outline clear next steps for your project.
