FAQs

Will I need planning permission or building regulations approval?

You may need planning permission if you are planning a larger extension. All extensions will need building regulations approval. An architect can assist with this and if planning permission is required. A reputable contractor will also be able to advise you if this is needed as well.

Will my garage conversion cause disruption to the rest of the house?

It shouldn’t do. Most companies will do all the interior work first, and the last job to do will be creating the opening from the house to the conversion. A reputable company will make sure they cause as little disruption as possible during this time.

do i need building regs for a garage conversion?

Are you considering converting your garage into a more usable space in your home? If yes, then you’d probably want to know if you’ll require building regs before converting the garage. The answer to this question is yes. Although you may not require planning approval to convert your garage into a more usable space, but you’d usually need approval under the Building Regulations.

When re-structuring your garage into a habitable space, the following should be taken into consideration: structural alterations, ventilation, moisture proofing, insulation, fireproofing, escape routes as well as the submission of a building building notice or full plan application to the local council in order to inform them about the planned project.

• Walls

You’ll require an approval if you plan to infill the garage door with a window and a new wall. This is because the garage may have been built of a shallow slab which implies that a new foundation would be needed for the new wall construction.

• Floor

Even though there’s a high possibility that the garage floor is strong enough for domestic use since its designed to withstand the weight of vehicles, you may however need to upgrade to make sure it suitable for both thermal insulation and damp proofing. In addition, there may also be the need to to alter the floor level in such a way that it matches that of the remaining parts of the house.

• Ventilation

According to the Building Regulations requirements, there’s a need for adequate ventilation for each individual rooms which includes garage conversions for general health purposes. What’s going to determine the ventilation level that’ll be required is the frequency at which the room is used. Ventilation can be provided through purge or simply opening the window or via trickle ventilation.

Will the company deal with the building control application?

Most companies will make the building control application on your behalf and ensure that all the work is completed to the right standards. When a building inspector has inspected it, you’ll get a certificate. It usually takes around 6-8 weeks after completion to come.
