Can a detached garage be converted into a living space?

Yes. Converting a detached garage is a popular choice for home offices, gyms and annexes. It tends to involve a little more work than converting an integral or existing garage, because services such as electrics and heating need to be run to it, and if you intend to use it as separate living or an independent living space you are more likely to need planning permission to convert it. Our detached garage conversions page explains the options in more detail.
