Loft vs Garage Conversion: Which Adds More for Your Money?
Two of the most cost-effective ways to add a room without extending your footprint — and how to choose between them.
PhotoIf you need an extra room but don’t want the cost or disruption of a full extension, converting space you already have is often the smart move. The two usual candidates are the loft and the garage.
Garage conversion
Usually the cheaper option — often £8,000–£18,000 — and quicker, because the structure’s already there. Brilliant for a home office, snug, playroom or utility. The main things to check are head height, damp and where your boiler or consumer unit lives.
Loft conversion
More involved and pricier — a dormer loft conversion is typically £30,000–£55,000 — but it usually adds a proper bedroom (often with an en-suite), which tends to add more value. The deciding factor is head height and roof structure: we’ll measure up and tell you honestly what’s achievable.
So which one?
- Need a cheap, fast extra room? Garage.
- Need another bedroom and want to add value? Loft.
- Not sure your loft has the height? Get it checked before you fall in love with the idea.
We’re happy to look at both and give you a straight comparison for your home — no pressure either way.
