Planning North London House Extensions


Planning North London House Extensions 

Now is a good time to commission larger than usual house extensions. North London residents are benefitting from the relaxing of regulations that only applies until 30 May 2016 for extensions that are categorised as permitted development, and do not need planning permission. Until then, the size restrictions on single storey rear extensions have been raised to double what they were before 30 May 2013. That means that you can extend up to 8 metres from the rear wall of a detached house, or up to 6 metres if the house is attached, without having to apply for planning permission.  

These larger extensions are permitted as long as the local authority is informed in advance and able to carry out a consultation with neighbours. The only considerations they can take into account in deciding whether to withhold permission are ‘whether the impact on the amenity of all adjoining properties is acceptable’, and they only need to consider this if any objections to your proposals have been made by your neighbours. As soon as you have their permission, or if you haven’t heard from them within 6 weeks, by law you may go ahead with the extension. However, it must be completed by 30 May 2016 so this is a relatively small window of opportunity. 

Other Restrictions Apply 

All other restrictions still apply for permitted development house extensions. North London planning authorities will make sure that you don’t cover more than half of your surrounding land with an extension or additional buildings. Your single storey extension must not be more than four metres high, and the materials you use must be similar to the rest of the house. 

You cannot extend at the front of the house, and can only build a side extension if there is no road running beside it. If this is the case the extension cannot be more than half the width of the house. 

If you want to build a two-storey extension, it must be at the rear and cannot extend beyond three metres of the original wall of the house. That means where the wall stood on 1 July 1948 or the date on which it was built after that. It must also be at least seven metres from your rear boundary.
