What a garage conversion with a room above involves
This service suits you if your attached garage is used for storage rather than parking and you need both a ground-floor room and an extra bedroom. You get a structural check of the garage, a design for both floors, the approvals your nation needs, insulation and damp-proofing to modern standards and the build, carried out by vetted teams working under S&K.
Across Worcestershire we cover Worcester (WR1), Redditch (B48), Kidderminster (DY10), Great Malvern (WR8), Bromsgrove (B60) and Evesham (WR10), plus the smaller places around them.
Guide price in the West Midlands
Using our West Midlands rates, a garage conversion with a room above with 3 m × 6 m of new first-floor space (18 m²) comes to about £31,500–£46,000 (for the room above; converting the garage itself is priced after the survey), including VAT. Bigger or more glazed designs cost more per m². Professional fees for drawings and the structural engineer are listed separately on our prices page.

Rules in England
In England, converting a garage on its own often needs no planning permission, but building a room above a side garage makes a two-storey extension beyond a side wall, which needs planning permission costing £548 (or £575 for applications made from 8 December 2026). Some estates have conditions removing garage conversion rights, which we check first.
Approval in England: Householder planning application: £548 (or £575 for applications made from 8 December 2026). Lawful development certificate: £274 (about £288 for applications from 8 December 2026). Councils should decide householder applications within 8 weeks of validation.
Building regulations: Building regulations approval (full plans recommended) from the council or a registered building control approver, with a completion certificate at the end.
The Party Wall etc. Act 1996 applies, so notices may be needed for work on or near a shared wall or boundary.
Getting the design right
Stairs and access
The room above is usually reached from the existing landing, while the converted garage opens off the hall. If the levels do not work, a new stair inside the converted garage can serve the room above, which we test in the layout.
Infilling the garage door
The garage door opening is usually filled with a new wall and a window, on a new foundation, with brick to match. The new front wall needs a cavity, insulation and a damp-proof course, and the window position should line up with the room above.

Garage conversions with a room above in Worcestershire: questions
How much does a garage conversion with a room above cost in Worcestershire?
In the West Midlands our guide is £1,750–£2,550 per m² including VAT, so about £31,500–£46,000 (for the room above; converting the garage itself is priced after the survey) for 3 m × 6 m of new first-floor space (18 m²). Essential and Premium specs move that by roughly 8% down or 20% up.
How warm will a converted garage be?
As warm as the rest of the house, if it is built properly. In England the new walls, floor and roof must meet limiting U-values of 0.18 W/m²K for walls and floors and 0.15 for roofs, and new windows 1.4. We add insulation and a damp-proof membrane, and extend the heating.
Will losing the garage affect parking?
It can. If the garage counts towards required parking on your estate, the council may look at whether enough off-road spaces remain. Most households in practice park on the drive. We check your title and any planning conditions about the garage at the start.
Does the room above need a fire door if the garage is converted?
Once the garage becomes a habitable room, the fire separation needed between a garage and the house usually falls away. The new bedroom above still needs an escape window or a protected route to the stairs, and smoke alarms. If you keep part of the garage for storage, separation may still be needed, which we confirm with building control.
Will I need planning permission in Worcestershire?
Worcestershire is in England. Planning permission is needed: in England, permitted development only allows single-storey extensions to the side.
