Frequently Asked Questions
How much does a Gants Hill house extension cost?
Costs vary by size, design, and specification. As a guide:
-
£1,800–£2,500 per m² for standard builds
-
£2,800+ per m² for high-spec finishes
We provide fixed pricing and can phase works to suit your budget.
Do I need planning permission for an extension in Gants Hill?
Many single-storey rear extensions fall under Permitted Development, but size, height and materials rules apply. We’ll confirm your options, manage any Redbridge Council planning submission (if needed), and handle building control approval.
How long does an extension take?
A typical single-storey rear extension takes 10–16 weeks on site, depending on scale, structure (e.g., steelwork), and finishes. Two-storey or wrap-around schemes will take longer. We’ll set out a clear programme before works begin.
Can I live at home during the build?
Often, yes—especially for single-storey projects. We can phase works, provide temporary access and protection, and keep disruption to a minimum. For larger schemes, a short relocation during structural stages may be advised.
Will you work with my architect?
Absolutely. We can collaborate with your existing team or provide a full design-and-build service—including our free design offer when you appoint KT5 for construction.
