Hello my name is ***** ***** I will help you with this.
Is this an outdoor structure? How long has it been there?
Ok - planning depends on size etc, so you should speak to your local Council planning office.
I cant tell you whether it does because it varies from Council to Council.
But generally permission is needed if a building with overall height exceeding 2.5 mtrs in height and placed within 2 metres of any boundary will require planning permission. Height of the eaves must not exceed 2.5 metres. No part projects beyond any wall of the house that faces a road
But if its a permitted development then no permission is needed.
If for example they had pigeons in the loft, it would not need permission.
Can I clarify anything for you about this today please?
