Questions homeowners ask
Does a garage conversion need approval?
Building Regulations commonly apply because the space is changing from ancillary storage to habitable accommodation.
Can the existing floor be kept?
Only after checking damp, level and insulation performance; a raised or replaced floor may be needed.
Can I keep the garage door?
It can be retained in some designs, but replacing it with an insulated wall and window often improves comfort.
