Planning rules that apply in Herefordshire
In England a single-storey side extension can be permitted development if it is no more than 4 m high and no wider than half the width of the original house. Two-storey side extensions, and any side extension on designated land such as a conservation area, need a householder planning application.
The planning position for a specific Herefordshire address depends on its history and any designations, which is why we check it at the first visit.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
What should I budget for a side extension in Herefordshire?
Labour and material costs vary across the UK, so for Herefordshire we use our West Midlands factor (×0.97). The ranges include VAT and exclude design, structural and council fees.
Typical rates in Herefordshire: £1,700 to £3,300 per m² including VAT, depending on specification.
| Size | Essential | Standard | Premium |
|---|---|---|---|
| 2.5 m × 5 m 12 m² | £21,000 – £26,000 | £23,500 – £31,000 | £30,000 – £40,000 |
| 3 m × 6 m 18 m² | £30,500 – £37,000 | £35,500 – £46,500 | £45,000 – £59,500 |

What we take care of
- Structure, roof tied into the house
- New openings through the side wall
- Planning route checked or application made
- Windows, doors and finishes to match
- Foundations near boundaries and any drains
- Survey, design and street-view drawings
Councils often prefer side extensions to sit slightly back from the front of the house with a lower roof, so the original building still reads clearly. We design to those principles from the start to avoid redesigns.
Extensions in and around Herefordshire
Towns we cover in Herefordshire include Hereford, Leominster, Ross-on-Wye, Ledbury. The West Midlands has a large stock of 1930s and post-war semi-detached houses, which are well suited to rear, side and over-garage extensions, plus Victorian terraces in the older inner areas.

Questions people ask about side extensions
Do you cover all of Herefordshire?
Yes, across the whole of Herefordshire. Site visits are free and there is no obligation.
Who do I contract with for a side extension in Herefordshire?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do I need building regulations approval in Herefordshire?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I build over my driveway?
Yes, if the foundations work and you keep any parking the council requires. Drains and services under drives are common, so we check before design.
Can I build a side extension without planning permission?
In England a single-storey side extension can be permitted development if it is no more than 4 m high and no wider than half the width of the original house. Two-storey side extensions, and any side extension on designated land such as a conservation area, need a planning application.
