Kitchen-diner rear extensions in Herefordshire
An open-plan kitchen, dining and family room that opens straight onto the garden. Rear extensions in Herefordshire: we cover 4 towns including Hereford, Leominster and Ross on Wye, with design, approvals and the build under one contract.
For Hereford kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later. Herefordshire has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
How much does a kitchen-diner rear extension cost in Herefordshire?
A kitchen-diner rear extension in Herefordshire is priced at £1,900–£3,100 per square metre including VAT as a guide, before kitchen fit-out and fees. The West Midlands is the baseline for our guide prices.

Do you need planning permission in Herefordshire?
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Should the sink face the garden?
If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.
Can I have underfloor heating?
Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.
Where does the cooker extraction go?
Through the new wall or roof, ducted to outside. Recirculating hoods are possible but less effective.
Do you cover all of Herefordshire?
We cover 4 towns and districts in Herefordshire, including Hereford, Leominster and Ross on Wye.
