Upgrade your home without the hassle—discover what permitted development allows in 2025 for doors, extensions, and glazing improvements.
Under 2025 rules, Permitted Development covers popular projects like single-storey rear extensions (up to 3m for semis, 4m for detached), loft conversions, rooflights, and outbuildings—provided you meet size, height, and placement guidelines. You’ll still need to follow building regulations, and certain areas (like Conservation Zones) may have extra restrictions.
If you’re planning a bigger extension, a Prior Approval application may be required. And even if permission isn’t, applying for a Lawful Development Certificate gives you proof your work is compliant.
At GFD Homes, we supply doors and glazing solutions that meet Permitted Development criteria—from bifolds under 4m to low-profile roof lanterns. Our team can advise on specs, U-values, and structural needs to help your project run smoothly.
