Clearing a garage for a conversion: what to sort before the builders
Why clearing comes first
Builders need an empty space to survey, strip out and work in. Contents left in place get dusty, damaged or in the way, and many builders will charge extra to move or store them. A clear garage also lets the designer and building control see the walls, floor and roof, which helps avoid surprises.
Clearing first also helps you see the true size of the space. A garage full of boxes always looks smaller than it is, and measuring the empty room gives the designer accurate dimensions for furniture, doors and windows.
Decide where everything will live
Converting the garage often removes the household's largest storage space. Before clearing, plan new homes for the things you will keep.
| Item | Possible new home |
|---|---|
| Garden tools and mower | Garden shed or storage box |
| Bikes | Bike store or wall-mounted shed racks |
| Seasonal decorations and suitcases | Loft, with boarding and a ladder |
| Tools and DIY materials | Shed, or built-in cupboards in the conversion |
| Bins and recycling | A bin store at the front of the house |
| Paint and chemicals | Use up, reduce and keep a small amount in a shed |
Clearing step by step
- Empty the garage zone by zone and sort into keep, sell, donate, recycle and dispose
- Move what you are keeping to its new home straight away
- Book charity collections and disposal for the rest
- Set aside paint, oil, chemicals and gas bottles for proper disposal
- Remove shelving and wall fixings unless the builder wants to keep them
- Sweep out and photograph the empty space for the builder
Pay attention to items that are fixed to the walls or roof, such as old cupboards, hooks, brackets and wiring for lights or a workbench. Leave electrical work to the electrician, but remove loose items and anything screwed to the walls so the builders start with a clean shell.
Things to find before work starts
- Gas and electricity meters, which must stay accessible
- The consumer unit and any sub-boards
- The water stopcock and any drains or gullies
- The boiler, flue and any pipes running through
- Any signs of damp, leaks or cracks in the walls and floor
- Roof or wall panels that may be asbestos cement
If meters or the boiler are inside the garage, the conversion design will need to allow for them. Moving meters is done by the supplier or network operator and can take time to arrange, so mention it early.
Asbestos in older garages
Garages built before 2000 can have asbestos cement roof sheets, wall panels, soffits or flue pipes. Have anything suspect tested before conversion work starts, because the builders will be cutting, drilling and stripping. Asbestos cement can often be removed carefully, but it must be handled and disposed of correctly.
Tell the builder about anything you have had tested and share the results, as they will need to plan their work around it.
Approvals to check
Many garage conversions do not need planning permission if the work is internal and there is no extension, but some homes have planning conditions requiring the garage to be kept for parking. Converting a garage to a habitable room does need building regulations approval. Sort out both before clearing furniture and fitting into the new room.
If you live in a flat, a leasehold house or a listed building, there may be further consents to get from the freeholder or the local authority. Check these before booking a clear-out, so you are not left with an empty garage and a project that cannot go ahead.
Building storage into the conversion
Because the conversion removes storage, it is worth designing some back into the new room or the rest of the house. Thinking about this while clearing helps decide what to keep.
- A full-height cupboard across one wall for coats, shoes and household items
- A utility area with space for a washing machine and tumble dryer
- Built-in shelving or a desk with drawers for a home office
- A storage bench under the window
- A boarded loft with lighting for seasonal items
Garden tools, bikes and fuel are best kept outside the house in a shed or bike store, rather than in the converted room.
If you plan to keep a small part of the garage as storage, behind a new wall, building control may still require fire separation between the remaining garage and the new habitable room. Raise this early with the designer so the layout works.
Frequently asked questions
How far ahead should I clear the garage before a conversion?
Aim to have it completely empty at least a week before the builders start, so there is time to deal with anything unexpected. For a packed garage, start sorting four to six weeks ahead. The designer and building control may also want to see the empty space before drawings and approvals are finalised.
Will the builder clear the garage for me?
Some will remove a few items or old shelving as part of the strip-out, but most expect the garage to be empty and will charge extra for clearing contents, or may not be licensed to carry household waste. A separate clear-out before the builders arrive usually costs less and lets you decide what is kept.
What if my meters are in the garage?
Meters, the consumer unit and stopcock often sit in garages. They must remain accessible after the conversion, so the design may include a cupboard around them or arrange to relocate them. Moving gas and electricity meters is done by the supplier or network operator, so contact them early as lead times vary.
