When a bedroom extension makes sense

  • Growing families
  • Homeowners who want an en-suite master bedroom
  • Multi-generational households

New bedrooms on an upper floor need an escape window or a protected route to the outside under the building regulations. We design the window sizes and stair route to meet that from the outset.

Will the council need to approve it?

In England a two-storey rear extension is permitted development only if it projects no more than 3 m from the original rear wall, sits at least 7 m from the rear boundary, matches the roof pitch and uses obscure, non-opening side windows upstairs. Most two-storey extensions therefore go through a householder planning application, which costs £548 from 1 April 2026 and normally takes about 8 weeks.

The planning position for a specific Huyton address depends on its history and any designations, which is why we check it at the first visit.

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.

Applications are decided by the local planning authority (your district, borough or unitary council).

Our process, step by step

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.

  2. Design and approvals

    Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.

  3. Fixed written price

    You receive a written, itemised price and programme. Nothing starts until you are happy with it.

  4. Build and sign-off

    Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.

Questions people ask about bedroom extensions

Do I need building regulations approval in Huyton?

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

How long does a bedroom extension take to build in Huyton?

On site, typically 14 to 22 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.

Do you cover all of Huyton?

Yes. We cover Huyton and the surrounding parts of Merseyside. Site visits are free and there is no obligation.

How much does a bedroom extension cost?

Our guide range is about £1,520 to £3,040 per m² including VAT. A bedroom with an en-suite of about 18 m² is typically £32,000 to £42,000 at standard spec, depending on whether it is part of a larger two-storey build.

Does an en-suite need a window?

No, but it needs mechanical extraction that meets the building regulations. We design the duct route at the drawing stage.
