An integral garage conversion transforms an attached garage into habitable living space — a home office, bedroom, playroom, utility room or annexe. Because the structure already exists (the garage sits within the main house footprint), no new foundations or external walls are needed. The work is primarily insulation, a new floor, boarding, plastering, heating, electrics and a new front opening treatment. It's the fastest and most cost-effective space addition available to London homeowners, and planning permission is almost never required.
Every Ealing project includes a free desk-based planning assessment before we quote. We know the local planning officers, party wall surveyors and approved inspectors by name.
