Homes in the North West

Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.

What does a wraparound extension involve?

Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.

  • Party wall process with both neighbours if needed
  • Glazing, insulation, plastering and electrics
  • Optional kitchen supply and installation

How much does a wraparound extension cost in Formby?

Do you need permission for a wraparound extension in Formby?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.

What can change the price or programme?

  • The corner steel connection is the critical detail and is designed by a structural engineer.
  • An open-plan space this size needs a heating plan, often underfloor heating.

How does the project run?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Wraparound extensions: common questions

Does a wraparound need planning permission?

Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.

Can we keep part of the kitchen working?

Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.

Yes. Formby is within our coverage for wraparound extensions, along with nearby Maghull and Southport.
