About our garage conversion openings service in Poole
If you live in Poole, garage conversion openings can usually be planned and priced after a single survey visit. The wider Dorset area is covered as well. We cover BH12, BH13, BH14, BH15 and BH17, and we fix the price in writing once the layout and scope are agreed.
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.
Things to plan for
- 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.
- 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.
- 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 structural part of a garage conversion, covering the infill foundation, the wall and any new opening, typically takes one to two weeks. The full conversion with insulation, electrics, plastering and flooring takes longer, depending on the scope.
- 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.
How the job runs in Poole
Free visit
A short visit to Poole to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
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.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Poole
For Poole, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about garage conversion openings in Poole
Who approves garage conversion openings in Poole?
Structural work in Poole needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
What happens at the survey visit in Poole?
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.
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.
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.
Can you work on older or listed homes in Poole?
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.
