Building extensions

When considering building extensions for your home there are bound to be a multitude of questions that you would like to ask.

For starters, will your building extensions require planning permits and what will happen if these applications are denied? The best way to ensure that your intended extensions are approved is to ensure that you consult with a registered building company on the matter before approaching any building or planning councils.

In the UK specifically, building extensions don’t explicitly require planning permits as long as you make sure to adhere to the building regulations in place for your area. If you would like to go ahead with building alterations or extensions to your home, ascertain that you are in accordance with the following conditions:

  • No more than half of the land that surrounds the original house can be covered with additions or building alterations.
  • Single storey rear extensions cannot exceed four meters.
  • You may not make extensions forward of the principal elevation or side elevation of the house fronting a highway.
  • If the extension is more than one storey, it cannot extend more than 3 meters beyond the rear wall of the original house.
  • Your extensions may not exceed the highest part of the existing roof.
  • In a detached house, the single-storey rear extension cannot extend more than four meters beyond the rear wall of the original house. In an attached house, the limit is three meters. These limits can increase or change subject to the neighbour consultation scheme.
  • The new extensions eaves and ridge height cannot be higher than the original house.
  • If the extension is two-storey, it cannot be closer than 7m to any rear boundaries.
  • The materials used must be similar to those of the existing house.
  • Any verandas, balconies and raised platforms will require planning permits.

These are just a few of the regulations in place that will allow you to go ahead with building extensions and alterations without planning permission in the UK. It is best to ensure that you are aware of all of the regulations with the assistance of a professional and registered building company.
