Towns in Herefordshire
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.
What we take care of
- Data cabling and plenty of sockets
- Sound insulation to the adjoining rooms
- Layout for desk, storage and video calls
- Window and rooflight placement to avoid screen glare
- Heating or cooling sized for the room
North-facing glass and rooflights give steadier light for screen work. Where the office faces south, we use deeper reveals or external shading to keep glare and heat down.

Planning and approvals in Herefordshire
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
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 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).

Common questions in Herefordshire
Do you cover all of Herefordshire?
Yes, across the whole of Herefordshire. Site visits are free and there is no obligation.
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 see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Herefordshire, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How much does a home office extension cost?
Our guide range is about £1,790 to £3,300 per m² including VAT. An 11 m² standard-spec office is typically £22,500 to £29,000 in Herefordshire.
Is an attached office better than a garden office?
An attached office shares the house heating and broadband, adds floor area to the home, and needs no garden path in the rain. A garden building can be cheaper and quicker but is a separate structure.
