Planning and regulations
In England, some single-storey rear extensions to houses can be built as permitted development, within limits on depth, height and materials. Flats and maisonettes do not have permitted development rights, and listed buildings, conservation areas and some new estates have extra restrictions. Side, wraparound and double-storey extensions usually need planning permission.
Almost every extension needs Building Regulations approval. If you build on or near a wall or boundary you share with a neighbour, the Party Wall etc. Act 1996 may require you to give them notice.
