Do I need planning permission in Ross-on-Wye?
In England any side extension over one storey, including a room built over a side garage, needs a householder planning application. The fee is £548 from 1 April 2026 and councils aim to decide within 8 weeks.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).
Local to Ross-on-Wye
We cover Ross-on-Wye and the postcode districts HR9. Nearby, we also take on projects in Ledbury (11 miles), Hereford (12 miles), Leominster (24 miles).
Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
What we take care of
- New floor structure, walls and roof
- Opening into the existing first floor
- Insulation, electrics, heating and finish
- Structural survey of garage walls and foundations
- Design and householder planning application
Fitting the new room to the existing landing is the planning puzzle inside the house. We design the connection first, then the roof, so the extension does not end up with awkward steps or a corridor through a bedroom.

Your questions about an over-garage extension in Ross-on-Wye
Will my neighbours in Ross-on-Wye 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.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Ross-on-Wye, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Ross-on-Wye?
Yes. We cover Ross-on-Wye and the surrounding parts of Herefordshire. Site visits are free and there is no obligation.
Does building over a garage need planning permission?
In England and the rest of the UK, adding a storey over a side garage almost always needs a planning application, because two-storey side extensions are outside permitted development.
How much does a room over a garage cost?
Our guide range is about £1,750 to £3,300 per m² including VAT. A single-garage room of about 12 m² usually costs £24,000 to £31,500 at standard spec, more if the garage needs rebuilding.
