If you’re planning some home improvements this year, you may be considering a house extension which many do to enlarge their living space and renovate their property. While some have concerns about how much hassle a home extension is, with specialist help, it can actually be pretty simple. One of the areas to factor into your designs is the planning permission required for house extensions. Here’s our simple guide to the rules you need to know about.
Are Home Extensions Permitted Developments?
Luckily, most extensions fall under ‘permitted developments’, meaning they don’t require full planning permission. However, to qualify, your designs must meet certain specifications. This usually applies to single storey, rear extensions in residential houses, so consult with your builder or local authority if considering a multi-storey, side extension or projects for flats and maisonettes. While you can read the full outline of specifications on the Government’s planning portal, fundamental limits include no more than half the land around the original house being covered by the extension. The height of the extension should be no more than 4 metres, using similar materials to that of the existing house. The extension must not be built more than 3 metres to the rear of an attached house or 4 metres for a detached house. However, this could change after May 2019, and larger extensions will be subject to a neighbourhood consultation scheme.
What about Building Regulations?
While most extensions won’t require planning permission, some builds must gain approval under Building Regulations. These regulations set the standards for design and construction to ensure the safety of anyone using the building, so the rules are there to protect you and anyone else in your home. Areas which may need to satisfy Building Regulation requirements including drainage, doors and windows, internal and external walls, electrics, kitchens, bathrooms, flooring, foundations, ventilation, fire safety, structural openings and roofs. You should also check whether your plans fall under the Party Wall etc Act 1996. Regulations may also cover energy efficiency, including the addition of solar panels and recycling of water tanks.
