Planning Information: Home Extensions
Porch
For a porch, you will need to apply for planning permission if:
- The ground floor area (when measured externally) would exceed 3 square metres.
- Any part of the porch would be more than 3 metres above ground level.
- If any part of the porch were within 2 metres of any boundary and the highway.
What this means is:-
When planning a porch, there a 3 factors to consider:-
- The ground floor area of the proposed porch
- Its height
- Distance from and boundary and highway
Provided the structure would not exceed 3 square metres (when measured externally), would be no higher than 3 metres and would be located no closer than 2 metres from any boundary and highway, then planning permission would not be required. If you live in a Listed Building, you will require to apply for Listed Building Consent.
In certain circumstances however, your "porch" may be of a size where it is not considered a "porch" structure anymore (within the meaning of the amended General Permitted Development Order 2008) but an extension in its own right by virtue of its size for example. Normally, if you do not meet the criteria set out within the Order, you would require planning permission. However, if you chose to add a porch to the side of your property for example, provided you met the relevant criteria (see:- I want a side extension), your proposal may well be considered as permitted development which means you would not require planning permission.
