Wraparound extensions in Milton Keynes

Covering Milton Keynes

We work in Milton Keynes (MK1, MK4, MK6) and the places around it, including Bletchley, Leighton Buzzard and Buckingham.

Homes in the South East

The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.

What do you get with a wraparound extension?

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.

How is a wraparound extension approved in Milton Keynes?

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. Most need householder planning permission, which usually takes around eight weeks once validated.

What should I think about before starting?

The corner steel connection is the critical detail and is designed by a structural engineer.
Roof water from an L-shape needs careful falls and outlets.

What people ask before starting

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.
