Can I build an extension to my house without having to seek planning permission?
The construction of an extension does not generally require planning permission when it is to the rear of the house, if:
Terraced and Semi-Detached Houses: If the house has not been previously extended, the floor area of the proposed extension cannot exceed 40m2. This exemption also allows for extensions above ground-floor level (if the house is semi-detached or terraced, the area of the above ground extension cannot exceed 12m2). This means, for a typical semi-detached house, one could have a ground floor extension of 28m2 & 1st floor extension of 12m2 without applying for planning permission. Any above ground floor extension shall be a distance of not less than 2m from any party boundary.
Detached Houses: As with terraced and Semi-detached above, the overall area of extension must be less than 40m2. This exemption also allows for extensions above ground floor level, the are above ground floor are cannot exceed 20m2. One could therefore have a ground floor extension of 20m2 & a 1st floor of 20m2. Any above ground floor extension shall be a distance of not less than 2m from any party boundary.
Both Cases: If the proposed extension is in addition to an existing extension, overall areas of all extensions must not be more than 40m2 including extensions which needed permission, e.g. to side of house.
Can I cover my entire back garden with an extension of 40m2?
No, an extension shall not reduce the "Private Open Space" of the back garden to less than 25m2.
Does an attic conversion require planning permission?

Can I convert my garage to living accommodation without permission?
Yes, subject to the provisions of Part 1 of the 2nd Schedule to the Planning & Development Regulations 2001 (i.e. the garage must be attached to the dwelling).
Can I build an extension to the side of my house?

Can I erect Solar Panels to my house?
