Here’s what you need to know:

Small porch extensions to a house may be exempt, but anything bigger will require planning permission.

You don't need planning permission if your porch can meet all of these conditions:

It is more than 2m from the nearest road.

It is no more than 2 square metres.

If it has a flat roof, the roof is no more than 3m high. If it has pitched roof, it is no more than 4m high.

Some other important things to consider when planning a build:

Anything you build (regardless of planning) will have to comply with the Building Regulations. These govern everything from energy performance to the size of window openings.

You will need to appoint project supervisors to ensure your build goes safely.

Protected structures and conservation areas are a different story - the standard exemptions listed here will not apply.

Consider using the services of a registered Architect, Engineer or Surveyor ​who will be familiar with the planning system.
