Common Questions

How long does the whole process take?

From initial consultation to planning approval typically takes 10-14 weeks. The design phase is usually 2-4 weeks, and planning decisions take 8 weeks for standard applications.

Do I definitely need planning permission?

Not always. Many extensions fall under 'permitted development' rights and don't need formal planning. Our PD Checker can give you an initial indication, and we'll confirm during your consultation.

What's the difference between planning drawings and building regs?

Planning drawings show what your project will look like and are used to get council approval. Building regulations drawings are more technical and ensure the construction is safe and compliant.

How much does an extension typically cost?

Costs vary hugely based on size, specification, and location. A rear extension might be £40k-£100k, while a double-storey could be £80k-£200k+. Our cost calculator can give you a better estimate.
