Covering Brighouse
Postcode districts we cover around Brighouse include HD2, HD6, HX5. We also work in nearby Halifax (3 miles), Cleckheaton (3 miles), Liversedge (4 miles), Huddersfield (4 miles).
Just over the South Yorkshire border, Darton is about 13 miles away. Yorkshire and the Humber combines stone-built terraces in the Pennine towns with brick semis and newer estates elsewhere, so materials and roof details need matching with care.
Planning and approvals in Brighouse
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 Brighouse address depends on its history and any designations, which is why we check it at the first visit.
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.
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).
Included in a typical project
- Sound insulation to the adjoining rooms
- Heating or cooling sized for the room
- Data cabling and plenty of sockets
- Window and rooflight placement to avoid screen glare
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.

Your questions about a home office extension in Brighouse
Will my neighbours in Brighouse be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
How long does a home office extension take to build in Brighouse?
On site, typically 8 to 12 weeks once approvals are in place. Before that, allow 4–10 weeks design and approvals.
Do you cover all of Brighouse?
Yes. We cover Brighouse and the surrounding parts of West Yorkshire. Site visits are free and there is no obligation.
How much does a home office extension cost?
Our guide range is about £1,740 to £3,200 per m² including VAT. An 11 m² standard-spec office is typically £22,000 to £28,000 in Brighouse.
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.
