Garage Conversion Architectural Designers
You park on the drive and the garage is full of clutter. It could be the extra room you need — often without planning permission. We'll tell you straight.
We know what's keeping you up at night
- “We've outgrown it.” You need one more usable room without building anything new.
- “It's freezing and damp in there.” You're not sure it can ever be comfortable.
- “Is it worth it?” You want to know the cost and the value before you start.

£25,000 – £40,000 build cost
Room for an office plus a snug, or a large open space.

Do I need planning permission to convert my garage?
Usually no — most garage conversions are permitted development. We confirm this for you on the first call so you know your route.
Can a cold garage really become a warm room?
Yes, with the right insulation, damp proofing and ventilation. That's exactly what the building regulations drawings cover.
How long does a garage conversion take?
Design is quick — often a few weeks. The build is usually four to six weeks on site, as there's no new structure to build.
Will I lose value by losing the garage?
In most areas a usable room adds more value than a garage you park in front of. We give you the real numbers for your street.
