Garage Conversion Project Timeline

If you’re thinking about having a garage conversion, it’s important to have a sense of how long the project is likely to take, so you can make sure it fits into your schedule.

It can be difficult to say with certainty how long the average garage project will take, as it depends on the size of the conversion. To give you a rough idea, we’ve put together a guide of how long it could take — but bear in mind yours could vary significantly from this.

How long will a garage conversion take?

Research: 1 week

It’s always important to do your research when you’re choosing home improvement pros. With a garage conversion, it’s even more important, as you’ll be working with the company over a long period of time. Get written quotes from a number of tradespeople.

After you’ve got several quotes, you can compare the prices along with the ratings and reviews of the pros. Make sure that each quote is specifying similar materials and designs. You can then choose the ideal pro for your budget.

Planning and design stage (without planning permission): 1-2 months
Planning and design stage (with planning permission): 2-4 months

Once you’ve chosen a tradesperson for your garage conversion, you’ll need to have the project designed. This can take up to a month, depending on the complexity of the design work.

You’ll also need to investigate planning permission. If your project does not require planning permission, expect to wait 1-2 weeks for building regulations approval. If your project does need planning permission, expect to add another 2 months for this process.

Building stage: 1-4 months

The time it takes to convert the garage can vary hugely depending on the size of the garage and the complexity of the project. For a small single garage conversion with minimal plumbing and electricity work required, expect the conversion to take around 6 weeks. For a large double garage conversion with multiple new rooms being added, the building process could take 4 months or even longer.

Total time: 2-8 months

Most smaller garage conversions will take around 3 months to complete. For larger double conversions which need planning permission, expect the process to take around 6 months.
