About a kitchen extension with bedrooms above

This service suits you if your kitchen is too small and you also need another bedroom. Building both floors at once costs less than a single-storey kitchen extension now and a first floor later. You get a layout that works for cooking, eating and the garden, a bedroom plan that works upstairs, the approvals your nation needs and the build, carried out by vetted teams working under S&K. Kitchen units are priced separately.

We cover Abercynon (CF46) and the places around it, including Treharris (1.6 miles), Nelson (Mid Glamorgan) (1.9 miles) and Pontypridd.

Design points for Abercynon homes

Steel beams and the open-plan opening

Removing the old rear wall to make one large room means a steel beam, sometimes several, to carry the first floor and roof. The engineer sizes the steel and its supports, and we decide early whether you want a flush ceiling with the beam hidden or a downstand, as this affects ceiling heights.

Bedrooms over a kitchen

Bedrooms above need an escape window or a protected route to the stairs, plus good sound insulation from the kitchen below. We position the stairs, landing and bedroom doors so the new rooms connect naturally to the existing first floor.

How we'd run your project

  1. Visit and first ideas

    One of our team visits your house in Abercynon, checks the walls, roof and drains, and sketches out options with you.

  2. Drawings and permission

    Our designers produce plans and elevations, then we take care of planning or permitted development checks with the council covering Abercynon.

  3. Detail and price

    Construction drawings, engineer's calculations and building control sign-off, then a written fixed price for the build.

  4. Build it

    The new structure goes up first, then we open into the house, finish inside and get the completion certificate.

Questions about kitchen extensions with bedrooms above in Abercynon

How much does a kitchen extension with bedrooms above cost in Abercynon?

Our guide for Wales, which covers Abercynon, is £1,840–£2,480 per m² including VAT. A typical project with a 4 m × 3.5 m footprint on two floors (28 m² of new floor space) comes to about £51,500–£69,500 (kitchen units and worktops priced separately). Design and approval fees are extra, and we fix the build price in writing once the design is agreed.

Which postcodes do you cover around Abercynon?

We cover Abercynon (CF46) and nearby places including Treharris, Nelson (Mid Glamorgan) and Pontypridd, plus the rest of Mid Glamorgan. The first site visit is free.

How long does a kitchen extension with bedrooms above take?

Allow 4 to 8 weeks for survey and design, then the approval period (councils normally decide householder applications within 8 weeks), then 4 to 8 weeks of technical design, which can overlap. The build itself usually takes 14 to 20 weeks, longer for large or complex designs.

Can I keep using my kitchen during the build?

For part of it. The new structure can be built while your existing kitchen stays in use, but when the rear wall is opened and the new kitchen is fitted there will be several weeks without one. We plan when this happens and help you set up a temporary kitchen elsewhere in the house.

Can the kitchen be bigger than the bedrooms above it?

Yes. With planning permission, the ground floor can extend further than the first floor, giving a part single, part two-storey design. In Wales, permitted development allows the ground floor to go 4 m and the first floor 3 m beyond the original rear wall. We show both options at the design stage.
