Garage Conversion Costs

How much does a garage conversion cost?

These are example prices that we’ve received showing how much people have paid for having their garage conversions done. Whilst changing a garage – which just fill will junk anyway – to a living area is a great use of space, not having a garage isn’t to everyone’s taste. It could be that some people will be put off buying your house if you don’t have a garage – no matter how practical it is. Think carefully before you do it. The prices shown are mostly for complete jobs so encompass any paperwork that needs sorting, the building work, carpentry, electrical work and additions to the central heating. Please refer to the detailed description for more info.
