What are the planning and building rules for installing a toilet in the downstairs of a property?
Normally planning permission is not required for installing a toilet in an existing area of the property as the change is only internal. If the toilet is part of a wider project such as an extension permission may be required.
If you live in a listed building, then listed building consent will be required for any major changes.
Building regulations will apply to the installation of a toilet in a property, these will cover areas such as ventilation, plumbing and drainage, and size.
Common Questions
Widening or creating a new external doorway will likely fall under permitted development rights, meaning an application for planning permission is not required provided you meet limits and conditions set out in legislation. If the change is on the side or rear of the building it is more likely to comply with planning regulations.
If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.
New external doorways which create a new or widened opening must comply with building regulations as they may impact the structure of a building.
You will not need planning permission if a new or replacement driveway of any size uses permeable (or porous) surfacing which allows water to drain through, or if the rainwater is directed to a lawn or border to drain naturally.
If the surface to be covered is more than five square metres planning permission will be needed for laying traditional, impermeable driveways that do not provide for the water to run to a permeable area.
This guidance applies to houses, there are different rules for flats and maisonettes, converted houses, new houses or areas where there permitted development rights may be restricted.

Different rules apply if the awning is attached to the house itself. It may still be permitted development, but falls under the class of enlargement, improvement or alteration.
