Building a Porch on the front of your home
When planning a porch, there a 3 factors to consider:
- The ground floor area of the proposed porch extension
- Its total height
- Distance from and boundary and the highway
Provided the structure would not exceed 3 square m (when measured externally), would be no higher than 3 m and would be located no closer than 2 m from any boundary / 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. 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.
For a porch, you will need to apply for planning permission if:
- The ground floor area (when measured externally) would exceed 3 sq m
- Any part of the porch would be more than 3 m above ground level.
- If any part of the porch were within 2 m of any boundary and the highway.
A porch is normally exempt from Building Regulation Approval if it is built at ground level and is under 3 square m in floor area. This is provided that the glazing and fixed electrical installations comply with the appropriate sections of the building regulations (see competent person scheme)
For a porch to be exempt from building regulations approval:
- the existing front entrance door between the exisitng house and the new porch must remain in place.
- If the house has a ramped or level access for disabled people, the porch must not adversely affect access.
