What we take care of
- Survey, design and 3D layout options
- Structural design for the corner and openings
- Foundations, drainage and any manhole relocation
- Roof with glazing along the side return
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.
Covering Bootle
Across L9, L20, L21, L22, L23, L30, we can visit, measure and advise. The same team covers Litherland (1 mile), Wallasey (4 miles), Liverpool (4 miles), Maghull (5 miles), all within easy reach.
Across the North West, terraced houses with small rear yards suit compact rear and side return extensions, while suburban semis have room for more.
Will the council need to approve it?
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
How the project works
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Common questions in Bootle
Do I need building regulations approval in Bootle?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does a wraparound extension take to build in Bootle?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
Will my neighbours in Bootle be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
How much does a wraparound extension cost?
Our guide range is about £1,900 to £3,520 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £54,500 to £69,000 in Bootle before design and council fees.
