Two-storey rear extension in Newport Pagnell

We plan and build two-storey rear extensions for homeowners in Newport Pagnell. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Start with a free site visit, then a written price once the design is agreed.

We cover Newport Pagnell (MK16) as part of our Buckinghamshire work. In Buckinghamshire we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Newport Pagnell?

Whether your two-storey rear extension in Newport Pagnell needs a planning application depends on its size, your house and any local restrictions.

England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.

What are homes in Newport Pagnell like to extend?

Newport Pagnell has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.

How a two-storey rear extension in Newport Pagnell comes together

  1. Free site visit

    We measure the house and garden, look at the back wall, drainage and boundaries, and talk through what you want from the space.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Paperwork handled

    Planning, prior approval or permitted development, Building Regulations approval, structural design and party wall notices are all handled by us.

  4. Written price, then build

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

Two-storey rear extension questions in Newport Pagnell

How much does a two-storey rear extension cost in Newport Pagnell?

As a guide, £2,020–£3,020 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £60,500–£90,500 at that rate. Your written price follows the survey.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

Can I add an en-suite upstairs?

Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.

Including MK16, and the surrounding Buckinghamshire area.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
