Home Extensions Built for Sutton Coldfield Homes

Sutton Coldfield's larger Edwardian and interwar villas around Four Oaks and Mere Green, alongside the semis and detached homes closer to town, mean extension projects here vary hugely in scale — from a modest single-storey kitchen extension through to substantial family additions. We design and build every stage ourselves, so the same team that draws up your plans is the one on site delivering them.

We've delivered projects across Sutton Coldfield, including a full interior refurbishment featured in our portfolio, and bring the same design-and-build approach to extensions of any size.

  • Single, double-storey and side-return extensions
  • Full architectural design and structural engineering in-house
  • We liaise with Birmingham City Council planning on your behalf where required
  • 12-month workmanship guarantee, up to 5 years structurally

Federation of Master Builders, Gas Safe, NICEIC and REFCOM certified, with public liability and structural guarantees on every project.

Planning Permission for Extensions in Sutton Coldfield

Sutton Coldfield sits within the City of Birmingham, so planning applications are decided by Birmingham City Council rather than a separate Sutton Coldfield authority — Royal Sutton Coldfield Town Council handles local civic matters but isn't the planning authority. Many single-storey rear extensions still qualify for permitted development: generally up to 4 metres beyond the rear wall for a detached house (3 metres for an attached one), rising to 8 metres and 6 metres respectively with prior approval, subject to height and boundary rules.

Areas like the Four Oaks Conservation Area lose permitted development rights, meaning a full planning application is needed for most extension work there, alongside Sutton Park's protected surroundings on the town's western side. We check your property against these designations before recommending a design route.

Planning rules summarised here are for general guidance only and can change — we'll confirm exactly what applies to your specific property before any work begins.

Frequently Asked Questions

It depends on your property type, the extension's size, and whether you're in a conservation area such as Four Oaks. Many single-storey rear extensions qualify under permitted development; larger projects and anything in a conservation area generally need a full application to Birmingham City Council, which we assess for you upfront.
Planning decisions for Sutton Coldfield are made by Birmingham City Council, the statutory local planning authority. Royal Sutton Coldfield Town Council is consulted on local matters but doesn't decide planning applications.
A single-storey rear extension typically takes 6–12 weeks on site. Larger or double-storey extensions, or projects requiring planning permission first, usually run 4–9 months from design through to completion.
Yes — we regularly design extensions for conservation area properties. It means a full planning application rather than permitted development, and our architectural team manages that process with Birmingham City Council for you.
