Planning Permission & Building Regulations

UPVC Porches & Brick Porches

The planning rules for porches are applicable to any external door to the dwellinghouse.

Adding a porch to any external door of your home in Buckinghamshire, Berkshire, Middlesex, Oxfordshire, Hertfordshire & London is considered to be permitted development, not requiring an application for planning permission, provided:

• The ground floor area (measured externally) would not exceed three square metres.
• No part would be more than three metres above ground level (height needs to be measured in the same way as for a house extension).
• No part of the porch would be within two metres of any boundary of the dwelling house and the highway.

Please note: the permitted development allowances described above apply to houses - not flats, maisonettes or other buildings.

Building Regulations

Building a porch at ground level and under 30 square metres in floor area is normally exempt from the need for building regulation approval. This is provided that glazing and any fixed electrical installations comply with the appropriate sections of building regulations.

For a porch to be exempt from building regulations approval:

• The front entrance door between the existing house and the new porch must remain in place.
• If the house has ramped or level access for disabled people, the porch must not adversely affect access.
