 Trustindex verifies that the original source of the review is Google. Absolutely brilliant service from SwiftSpace Garage Conversions from start to finish. We had our garage turned into a living room, and honestly, it’s one of the best things we’ve done to the house.

The whole team were friendly, reliable and really easy to deal with. They turned up when they said they would, kept us updated throughout the job, and everything was left clean and tidy at the end of each day.

The quality of the work is spot on. The new room blends in perfectly with the rest of the house, you’d never know it used to be a garage. It’s given us loads of extra space and has completely changed how we use our home.

Couldn’t fault the experience and would happily recommend SwiftSpace to anyone thinking about a garage conversion. Thanks again to everyone involved!

Potentially, yes. A bedroom and en-suite can often be incorporated where there is sufficient space and suitable plumbing and drainage.

Can the annexe have its own entrance?

A separate entrance may be possible depending on the property, layout and any planning or Building Regulations requirements.

Can I add a small kitchen to a garage annexe?

Yes. Appropriate insulation, heating and ventilation can create a comfortable space suitable for regular use throughout the year.
