Planning garage conversion openings in Maidstone
For homes in Maidstone and the ME14, ME15 and ME16 districts, we handle garage conversion openings from survey to sign-off. We also cover the surrounding towns and villages in Kent. The beam is sized by a structural engineer and inspected before it is boxed in.
For integral garages with a bedroom above, the beam over the garage door matters even more, because it carries the front wall of the room upstairs. We arrange the survey visit, engineer's calculations, building control, propping, any steel and making good, with the structural items set out in one itemised written quote.
Worth knowing before you start
- Garages often hold gas meters, consumer units, boilers or water stopcocks. These are located at survey, and anything that needs moving is done by the right trade, including a Gas Safe registered engineer for any work on gas pipework.
- The price depends on whether the garage door beam needs replacing, the foundation needed for the infill, whether a new opening is formed into the house, the brick or cladding finish, and any fire separation work that has to be kept or added.
- The infill wall facing the street is the part everyone sees. Bricks and mortar are matched to the house as closely as possible, or the panel is rendered or clad, and the new window is aligned with the others on the front elevation.
- 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.
- Garage floors often sit lower than the house floor and may have no damp-proof membrane. The infill wall needs a damp-proof course linked to the existing walls, and the floor usually needs a membrane, insulation and screed raised to the house level.
How the job runs in Maidstone
Survey in Maidstone
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.

Building rules for Maidstone
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 Maidstone
Can you work on older or listed homes in Maidstone?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
How much do garage conversion openings cost in Maidstone?
As a guide, budget £1,100–£3,350 including VAT for garage door opening infill (structural part) in Maidstone, based on published UK cost guides adjusted for prices in the South East (+12%). 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.
What paperwork will I get when the conversion is done?
You should receive the engineer's calculations, a building control completion certificate for the conversion, and certificates for any electrical or gas work. Keep these together, as buyers' solicitors ask for evidence that a garage conversion was approved, especially where a garage has become a bedroom or living space.
Does the infill wall need foundations?
Yes. A new masonry wall across the garage door opening needs a proper footing, as the existing garage slab is usually not designed to carry it. A trench is dug across the opening and a foundation is formed to the engineer's and building control's requirements, then inspected before the wall is built.
Do I need planning permission to convert my garage?
Often not, because a garage conversion is largely internal work within permitted development. However, some newer estates have planning conditions that remove permitted development rights for garages, and listed buildings, flats and some front elevation changes need consent. Check your property's planning history with the council before committing.
What happens at the survey visit in Maidstone?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
