Do I need planning permission for my Extension or Loft Conversion?
As a general rule, if you wish to make additions or extensions that will affect the external appearance of your property you will need planning permission.
More restrictions apply to flats and maisonettes than to a house.
Internal alterations do not usually require permission, although you do need planning permission if you want to convert your property into separate dwellings i.e. flats or bedsits. Not all loft conversions require planning permission.
If you live in a conservation area or your building is listed planning permission may be required for work which would normally not require it – always check with your local authority.
If you have a situation which you think falls outside of these guidelines or are in any way unsure, it is best to contact your local authority who will give you the necessary guidance.
Planning issues can be contentious and if you proceed without any required consents you may be required at your cost to demolish or significantly alter any development undertaken.
What is permitted development?
You may be able to make certain alterations on a house (as opposed to a flat or maisonette) without the need for planning permission.
This is termed “permitted development” and it applies to an “original house” i.e. a house as it was first built, or as it stood on 1st July 1948 if it was built before that date. If an “original house” has not been extended (including loft conversions) you may be able to develop your property under these rights.
As permitted development is subject to limits on height and volume, and has many permutations, we advise you consult your local authority and/ or an architect.
Your local authority may have withdrawn permitted development rights if you live in a conservation area.
What will I be allowed to build?
Again, this is subject to many variables, and your initial inquiries should be directed to the local authority and an architect.
You can gain a general indication of what is likely to be approved by looking at other approved development of properties around your local neighborhood.
