Single Storey Extensions in Wolverhampton

Types of Single Storey Extension We Build

Rear extensions are the most popular single storey build in Wolverhampton — extending the back of the house into the garden to create a larger kitchen, dining space or family room, usually with bifold or sliding doors onto the garden.

Side return extensions suit the older terraced and semi-detached properties found across Tettenhall and central Wolverhampton, where an underused strip of land runs alongside the house. Infilling it transforms a narrow kitchen into a bright, open-plan space.

Wraparound extensions combine rear and side return into an L-shape — the biggest footprint gain a single storey build can deliver, ideal for a full kitchen-diner-lounge across the back of the house.

Garden room extensions add a light-filled living space, snug or home office with full-height glazing — a popular choice where families want a distinct room rather than one large open span.

Single Storey Extension Costs in Wolverhampton (2026)

Most single storey extensions in Wolverhampton cost between £1,800 and £2,500 per m², with side returns typically £2,000–£2,800 per m² because of the extra structural work along the boundary. As a guide, a typical 20m² rear extension lands around £36,000–£50,000.

Guide prices at the published £1,800–£2,500/m² and £2,000–£2,800/m² (side return) rates. Includes foundations, structure, roof, glazing, electrics, plumbing, plastering and decoration; excludes kitchen/bathroom fit-out. See the full 2026 extension cost guide for a detailed breakdown.

Planning Permission & Building Regulations

Many single storey extensions in Wolverhampton fall under permitted development: a rear extension can usually project up to 3m on semi-detached and terraced homes, or 4m on detached homes, without a full planning application — and larger schemes can often proceed under prior approval. Conservation areas in Tettenhall and Wightwick have tighter rules, and side returns there often need full consent.

Where a full application is needed, the planning fee is £258 and decisions typically take around 8 weeks through Wolverhampton City Council or South Staffordshire Council depending on where you live. We prepare drawings, submit the application and handle any conditions.

Building Regulations always apply. Building control inspects foundations, structure, insulation (Part L), electrics (Part P) and drainage, and we manage every inspection through to the completion certificate you'll need when you sell.

What's Included in Your Single Storey Extension

Every single storey extension we build includes: setting out and foundations, masonry to match your existing brickwork, structural steels where walls are opened up, a warm flat or pitched roof, windows and doors (bifold and sliding options), full electrics, plumbing and heating alterations, plastering, decoration and building control sign-off.

We do not subcontract the core trades. Brickwork, carpentry, roofing, electrics, plumbing and plastering are handled by our own team under one warranty, with a single project manager from quote to handover — and most builds complete in 8 to 12 weeks.
