Other restrictions you need to check before building an extension
The Original House rule
Permitted development guidelines for adding an extension to your house refer to the 'original house'. This means the property as it stood on 1 July 1948 or on the date it was built if after.
If an extension has been added to the original house then you have to factor this in to any development you can do under permitted development rights.
Article 4 Direction
A local council has the right to override permitted development rights. Check with your local office that there aren't any directives in place before you start planning your build.
A property can have a covenant attached to it by a previous owner as a condition of sale. This can be a restriction of any development of the property or building in the grounds of the property.
Your solicitor had a duty to inform you of this when you purchased the property so check with them that there hasn't been any previous covenants placed on your property.
Subject to stricter planning rules a listed building needs listed building consent from your local planning office and the permitted development rights might not apply.
Conservation Areas, National Parks, Areas of Outstanding Natural Beauty and World Heritage Sites.
As with listed building properties built in designated areas are subject to tighter control and will need approval from the relevant authority.
Always seek approval from your local planning authority before starting any building work.
