About our garage conversion openings service in the West Midlands
Garage conversion openings are the structural changes that turn a garage into living space: infilling the garage door opening with a wall and window, and often forming a new opening between the garage and the house. The existing lintel or beam over the garage door is checked, and any new steel is sized by a structural engineer.
If you are planning garage conversion openings in the West Midlands, the order of work matters as much as the steel: survey, calculations, approval, propping, installation, inspection and making good. We can survey in places such as Solihull, Smethwick and Halesowen and the villages around them. We run that sequence for you as one job with one point of contact.
Key points for your project
- Most garage conversions do not need planning permission, but some estates have conditions removing permitted development rights for garages, and listed buildings or flats need consent. Changing the front elevation can also need permission in some areas.
- A converted garage used as a bedroom needs a suitable means of escape, often an escape window, and every habitable room needs ventilation. These affect the size and type of window in the infill wall, so they are agreed before brickwork starts.
- The beam or lintel over a garage door was designed to span an open gap. It may be timber, concrete or steel, and in older houses it can be undersized or corroded, so the engineer checks it before anything is built underneath or above it.
- Forming a doorway from the house into the converted garage often goes through a load-bearing wall, especially the original external wall of the house where the garage is attached. That opening needs a lintel or beam designed by the engineer.
- An integral garage is usually separated from the house by fire-resisting construction. If part of it stays as a garage or store, that separation must be kept, and any new door between garage and house normally needs to be a fire door.
How the job runs in the West Midlands
Survey in the West Midlands
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

| Widening an internal doorway | £1,000–£2,500 | Opening widened with a new lintel or short beam, approval where structural, and making good |
| Steel beam replacement | £2,000–£5,500 | Propping, removing the failed beam, new steel on proper bearings, approval and making good |
| Building control fees | £250–£650 | Building notice or full plans fee and inspections; varies by council or approver |
Figures include our approximate regional adjustment for prices in the West Midlands (no adjustment) and are rounded. How these figures are worked out.
Approvals in the West Midlands
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Questions about garage conversion openings in the West Midlands
How much do garage conversion openings cost in the West Midlands?
As a guide, budget £1,000–£3,000 including VAT for garage door opening infill (structural part) in the West Midlands, based on published UK cost guides adjusted for prices in the West Midlands (no adjustment). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Which towns in the West Midlands do you cover?
We cover towns including Birmingham, Coventry, Wolverhampton and Dudley, plus the villages and smaller towns around them.
Can I knock through from my garage into the kitchen?
Usually, yes. The wall between an attached or integral garage and the house is often load-bearing, so the opening needs a lintel or steel beam designed by a structural engineer and approved by building control. If any of the garage stays as storage, the opening needs fire separation, such as a fire door.
Is my garage floor suitable for a living room?
Rarely as it stands. Garage floors are often lower than the house, may slope towards the door and usually lack insulation and a damp-proof membrane. The floor is normally built up with a membrane, insulation and screed or a timber floor to meet the house level and the building regulations.
What happens to the beam over my garage door?
It is checked by the engineer. Many can stay, carrying the wall above as before, with the infill built underneath. If it is timber that has rotted, a corroded steel section or simply undersized for the loads, it is replaced, with the wall or room above propped while the new steel goes in.
How long do the structural works for a garage conversion take?
Typically one to two weeks for the structural stage: digging and concreting the infill foundation, building the infill wall, and forming any new opening into the house. Building control inspections fit around these stages, and the insulation, electrics, plastering and flooring of the conversion follow on afterwards.
