Permitted Development
Navigating Permitted Development and Extensions in London
Permitted Development: A Basic Overview
Permitted development rights allow homeowners to extend or renovate their homes without the need for full planning permission, provided the project meets specific criteria. These rights, derived from national legislation, offer numerous opportunities to invest in your home while avoiding the time-consuming and costly planning process. If you also want to gain something beneficial with this right, reach out to the professional permitted development consultants from Studio : MASS.
Key Points of Permitted Development
1. Single-storey extensions: Typically allowed without planning permission if they adhere to size and design constraints.
2. Loft Conversions: Permitted if they fall within volume limits and do not exceed the highest part of the existing roof.
3. Outbuildings: Structures like sheds and garages are generally permitted if they don't exceed specific height and area limits.
4. Front Porches: Permitted if they are within size restrictions and not located within 2 metres of the public highway.
5. Designated Land Restrictions: Permitted development rights may not apply in conservation areas, National Parks, or other designated land.
6. Material Restrictions: Extensions should use similar materials to the existing property to maintain aesthetic continuity.
7. Volume Allowances: Extensions must not exceed 50% of the land around the original house.
Detailed Guidelines
1. Height Restrictions: Single-storey extensions must not exceed 4 metres in height.
2. Boundary Proximity: Extensions within 2 metres of a boundary must not exceed 3 metres in height at the eaves.
3. Rear Extensions: For terraced and semi-detached houses, rear extensions can extend back by up to 6 metres, or 8 metres for detached houses, under the Neighbour Consultation Scheme.
4. Roof Extensions: Must be set back at least 20 centimetres from the original eaves, unless it’s a hip-to-gable extension.
5. Balconies and Verandas: Not covered under permitted development and require full planning permission.
6. Windows and Doors: Must not protrude beyond the roof plane or be installed on side elevations unless they are obscure-glazed and non-opening below 1.7 metres from the floor.
7. Solar Panels: Generally allowed under permitted development, provided they do not extend significantly above the roofline.
Practical Advice for Homeowners
1. Lawful Development Certificate: Obtain this certificate to confirm your project falls under permitted development rights.
2. Professional Guidance: Consulting with architects and planning consultants ensures compliance and maximises the potential of your extension.
3. Prior Approval for Larger Extensions: For significant projects, obtaining prior approval from neighbours is crucial to avoid future disputes and complications.
