About a two-storey wraparound extension

A two-storey wraparound extension is an L-shaped addition that extends both the side and the rear of your house, on two floors. It gives one of the largest gains in floor space of any extension, typically a big open-plan kitchen and living area below and two or more bedrooms or bathrooms above. In England it needs planning permission, because the side part is more than one storey.

What it costs in Acocks Green

For budgeting in Acocks Green, allow around £120,500–£165,000 for a two-storey wraparound extension with an L-shaped footprint of about 28 m² wrapping the side and rear, on two floors (56 m² of new floor space). That's based on £2,150–£2,950 per m² including VAT for the West Midlands. Steelwork for wide openings is the item most likely to move the figure; we'll know once the engineer has designed it.

Design points for Acocks Green homes

Two roofs that meet

A wraparound needs the side roof and rear roof to join cleanly, often with a valley or hip where they meet. Getting pitches and ridge heights right keeps rainwater moving and avoids a bulky mass at the back corner, which neighbours and planners notice.

Phasing the build

A wraparound touches two sides of the house at once, so the kitchen and often the rear rooms are out of use for part of the build. We plan the sequence so you keep a working kitchen and bathroom for as long as possible, or advise when moving out briefly makes sense.

Questions about two-storey wraparound extensions in Acocks Green

How much does a two-storey wraparound extension cost in Acocks Green?

Our guide for the West Midlands, which covers Acocks Green, is £2,150–£2,950 per m² including VAT. A typical project with an L-shaped footprint of about 28 m² wrapping the side and rear, on two floors (56 m² of new floor space) comes to about £120,500–£165,000.

Who handles building regulations for a project in Acocks Green?

Which postcodes do you cover around Acocks Green?

We cover Acocks Green (B10, B11, B13, B25, B26 and B27) and nearby places including Shirley (West Midlands), Solihull and Washwood Heath, plus the rest of the West Midlands. The first site visit is free.

Can a wraparound extension be part single, part two-storey?

Yes. Many wraparounds keep the rear part single storey with roof lights over the kitchen and put the two-storey part to the side. This can reduce the effect on neighbours and the cost. We set out both options at the design stage, so you can compare floor space against price before choosing.

Does a wraparound extension need steel?

Almost always. Opening the corner of the house and the old rear wall to make one open-plan space means steel beams, and often a steel post or frame at the outside corner. The structural engineer sizes these, and the steel is ordered once the design is fixed, which is one reason a wraparound needs careful sequencing.
