A granny flat garage conversion can provide independent living space within your property, often used to accommodate an elderly parent, adult child, or long term guest while keeping them close to the main household.
At North East Garage Conversion, we design and build garage conversions that can function as self-contained living spaces where permitted, with careful attention to planning rules, Building Regulations and local authority requirements.
