What size porch can I build without needing building regulations approval?
Building a porch at ground level and under 30 square metres in floor area is normally exempt from the need for building regulations approval.
This is provided that glazing and any fixed electrical installations comply with the appropriate sections of building regulations.
To find out more about the building regulations for porches, visit Planning Portal.

Common Questions
A wall is a 'party wall' if it stands astride the boundary of land belonging to two (or more) different owners, for example the wall separating two semi-detached properties.
Some kinds of work carried out to a property may not be controlled by the building regulations, but may be work which is covered by the Party Wall etc. Act 1996. This is a separate piece of legislation with different requirements to the building regulations.
To find out more about party walls, visit Planning Portal.
The conversion of a garage, or part of a garage, into habitable space, will normally require approval under the building regulations.
As part of the garage conversion, it is likely that the original garage door will be in-filled with a new wall and possibly a window or door, and a new foundation may be needed for the new wall.
As well as the foundation, you also need to consider:
- Floor
- Walls
- Ventilation

Planning permission is not normally required for steps in a garden, however, permission may be required if the steps are part of a larger project such as a raised deck attached to the front of the house.
If the external steps are attached to the house and a roof is constructed, this will become a porch which has different rules attached. Read full details on the planning rules for porches in our common projects section.
Different rules may apply if you live in a designated area such as a conservation area or if the building you live in is listed.
External steps will not normally require building regulations approval unless they are part of the access to the building. If they are then you must ensure that you do not reduce the level of accessibility to the house.
You should contact your local planning authority for further project advice, alternatively, you can apply for a lawful development certificate for confirmation that any changes you make do not require planning permission.
Under the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended), you have a general permission to install an antenna up to a specific size on property without the need for planning permission. This general permission depends on your house type and area. Your local planning authority can give you more advice.
A carport can fall under permitted development rights provided it meets certain limits and conditions set out in legislation. If you exceed or fail to meet a requirement then you will require planning permission.
If not attached to the house, a car port will be treated as an ‘outbuilding’. A full list of requirements is available on our outbuildings common project.
