What is exempt development for garden rooms?

Typically, garden rooms up to 25 square metres are exempt, providing they meet specific criteria (single storey, maximum height of 3m to eaves, and other requirements). Always verify your project qualifies with your local authority.
How much value does a garden room add to my property?

What's the difference between a garden room and a shed?
Garden rooms are permanent building structures with professional construction standards, including proper insulation, electrical certification, and structural integrity built to last 25+ years. Prefabricated sheds are temporary structures lacking insulation, lacking electrical compliance, and typically last 5-10 years before deteriorating. BR Building Services builds permanent garden rooms that are weatherproof, year-round usable, and built to building regulations standards — not prefab sheds.
Can a garden room be used year-round?
Yes, properly insulated garden rooms with heating systems are fully usable year-round. BR Building Services installs double or triple glazing, thermal insulation, and heating solutions that maintain comfortable temperatures in winter and summer, creating a genuine extension to your living space.
Can I add electricity and plumbing to a garden room?
Absolutely. BR Building Services installs full electrical systems with RECI certified installation, plumbing for bathrooms or kitchens, and professional heating systems. All work meets Irish building regulations and safety standards, with proper certification provided upon completion.
What warranty and aftercare do you provide?
BR Building Services provides comprehensive aftercare support including a 10+ year durability guarantee on structural elements, electrical certification and support, and ongoing maintenance advice. We're here to ensure your garden room remains in perfect condition for decades.
