Frequently Asked Questions
How much does a Redbridge house extension cost?
Costs vary by size, design complexity, and specification. As a guide:
-
£1,800–£2,500 per m² for well-specified standard builds
-
£2,800+ per m² for high-spec finishes or complex structures
We provide fixed pricing and can phase works to suit your budget.
Do I need planning permission?
Many single-storey rear and side returns fall under Permitted Development (subject to rules on height, depth, materials and neighbour impact). Two-storey, wrap-around or conservation-area projects typically require full planning. We confirm PD eligibility, prepare drawings and manage submissions.
How long does an extension take?
Typical timelines (subject to scope and season):
-
Single-storey: ~10–16 weeks
-
Double-storey / structural reconfiguration: ~16–28 weeks
Your programme will be agreed up-front and updated throughout the build.
