Outbuildings are the perfect way to add extra space to your property when you need a bit of quiet from the main house. Whether it's for a garden office, gym or workshop, an outbuilding can add value to your home and increase your quality of life.

Outbuilding costs in CO1 range from the cheapest of £9,200 (Ace Locksmith based in CO3) to the dearest of £9,688 (Open Plan Renovation based in CO4), but these are just estimates.

Comparing extension builders estimates for building an outbuilding gives you an idea of who will be better value, but the best way to compare costs is to get actual quotes.
