The Ultimate Way to Maximise Your Ground Floor
A wrap-around extension combines a rear and side extension into a single L-shaped footprint, delivering more space than any other single-storey option. It's the ideal choice for larger families who want a dramatic open-plan kitchen, dining and living zone. We've built these across Stockport, Cheadle, Wilmslow and Cheshire.
Combines rear and side footprints for the biggest possible gain
Wide, uninterrupted living zones that transform how you use your home
Substantial square footage that is one of the strongest returns on investment
Popular Wrap-Around Design Ideas
Every wrap-around extension we build is unique. Here are some of the most popular layouts our clients choose to make the most of their expanded L-shaped footprint.
Broken-Plan Kitchen & Living
Use the extra width and depth of the L-shape to create distinct but connected zones, a sociable kitchen island, a dining area and a relaxed living space, all flowing together under one roof.
Glazed Garden Corner
The corner created by a wrap-around is perfect for a fully glazed dining or seating nook, wrapping bi-fold or sliding doors around two sides to bring the garden right into the home.
Family Hub & Utility
The side return element is ideal for a boot room, utility or larder, while the rear opens into a spacious family lounge, giving busy households the storage and living space they need.
Snug & Home Office
The added footprint lets you carve out a quiet snug or a purpose-built home office off the main open-plan space, properly insulated and designed for productivity without losing the airy feel.
Choosing Your Roof Style
Because a wrap-around covers a large L-shaped footprint, the roof design is crucial for bringing daylight deep into the plan. Here are the main options we offer.
Flat Roof
The most cost-effective option for a large footprint. Modern flat roofs use single-ply membrane systems (EPDM or GRP) with a 25-year guarantee. They allow maximum internal ceiling height and are perfect for incorporating multiple roof lanterns or skylights to light the centre of the plan.
Pitched / Tiled Roof
A pitched roof matches the style of most traditional British homes, helping a large wrap-around sit comfortably against the original house. Tiled to match your existing roof with carefully designed ridge lines and valleys, essential where the two arms of the L meet, for a truly integrated finish.
Lantern / Glass Roof
Roof lanterns or a fully glazed section flood the deep centre of a wrap-around with natural light from above, which is vital on a larger footprint. Available in aluminium or timber frames, they create a dramatic focal point and stop the middle of the plan feeling dark.
Why Wrap-Arounds Usually Need Planning Permission
Because a wrap-around combines a rear and a side extension into one L-shaped footprint, it almost always exceeds permitted development limits, meaning a full planning application is usually required. Don't worry, we prepare and manage the whole application for you. Here are the key reasons planning is needed and what we handle:
A rear extension alone might fit within permitted development, but adding the side return typically pushes the combined footprint beyond the 3m to 4m rear and side-return allowances, triggering a full planning application.
Side extensions under PD are restricted to half the width of the original house and a single storey. Wrapping this around the rear almost always means the design falls outside permitted development and needs council approval.
The large footprint of a wrap-around often approaches or exceeds the rule that extensions must not cover more than 50% of the land around the original house, another reason full planning is normally required.
From architectural drawings and design-and-access statements to submitting the application and liaising with your local planning officer, we manage the entire planning process end to end so you don't have to.
Conservation areas, listed buildings, and some housing estates have additional restrictions. We assess exactly what your project needs and manage the full planning application as part of our service, starting with a free site survey.
Week-by-Week Build Timeline
Here's a typical timeline for an L-shaped wrap-around extension, so you know exactly what to expect at each stage of this larger project.
Groundworks & Foundations
Site set up, excavation across the larger L-shaped footprint, drainage diversions, and reinforced concrete foundations poured to structural engineer specifications.
Brickwork, Steels & Walls
Cavity wall construction with DPC and insulation, plus the substantial steel beams needed to remove the rear and side walls and open up the space. Openings formed for glazing.
Roof & Weatherproofing
Roof structure with valleys where the two arms meet, insulation, lanterns and covering installed. Windows and doors fitted so the extension becomes watertight.
First Fix Services
Electrical wiring, plumbing, heating pipework, and underfloor heating installed across the full footprint before plasterboarding.
Plastering & Second Fix
Internal walls plastered, kitchen and any utility or bathroom fitted, sockets and switches installed, tiling and flooring laid throughout the open-plan space.
Finishing & Handover
Final decoration, snagging, building control sign-off, and handover. External landscaping and patio works completed.
Wrap-Around Extension FAQs
Everything you need to know about wrap-around extensions, answered by our team.
Do I need planning permission for a wrap-around extension?
In most cases yes. Because a wrap-around combines a rear and a side extension into one L-shaped footprint, it usually exceeds permitted development limits and requires a full planning application. We prepare and manage the entire planning submission on your behalf, from drawings through to dealing with the local council.
How much does a wrap-around extension cost, and does it add value?
Wrap-around extensions in the Stockport/Cheshire area typically range from £55,000 for a straightforward L-shaped build up to £120,000 for a large, high-spec open-plan space with premium glazing and a full kitchen fit-out. Because they add substantial square footage and a sought-after open-plan layout, they are one of the strongest additions for home value. We provide a fixed-price quotation after our free site survey.
Are structural steels needed for a wrap-around extension?
Yes. Wrap-around extensions almost always require significant steel beams (RSJs) to remove the existing rear and side walls and create the large open-plan space that makes this design so popular. A structural engineer calculates the steel sizes, lintels and foundation loads, and we arrange all structural engineering as part of our service.
How long does a wrap-around extension take to build?
Most wrap-around extensions take 14 to 22 weeks on site because they cover a larger footprint and involve more structural work than a simple rear extension. Add roughly 8 to 14 weeks beforehand for design, the full planning application and building regulations sign-off, all of which we manage for you.
Will a wrap-around extension leave the middle of the room dark?
Not with the right design. Because a wrap-around is deep, we plan roof lanterns, skylights and full-height glazing to bring daylight into the centre of the plan and into the existing rooms behind. Careful layout of the glazing is a core part of our design process so the whole space feels bright and airy.
