m9qmoh-scfe-sergei-zolkinBefore you start building work on your home, you will most likely need to apply for planning permission, or at least consult your local authority before work begins. The type of planning permission you need differs depending on the work you are having carried out and your location.

It is the responsibility of both the home owner and building contractor to make sure that you have the correct permission to modify your home.

To help you understand some of the basics of planning permission and building regulations, we’ve outlined the requirements for the following building work.

Planning Permission for House Extensions
Neighbour Consultation Scheme
Planning Permission for Loft Conversions
Planning Permission for Renovation Work


Planning Permission for House Extensions


House extensions are actually exempt from planning permission, so long as they meet particular limits and requirements. These include, but are not limited to, the following:

– That no more than half the area of land surrounding the original house is covered by additions

– The extension must not be higher than the highest part of the existing roof

– A single-storey rear extension is not allowed to extend beyond the rear wall of the original house by more than 3 metres

– The maximum height must be no higher than 4 metres (single-storey structure).

For full detailing of the limits and conditions, you should view the relevant pages in the Planning Portal. If your planned extension fails to meet the exemption requirements, then you will need to apply for planning permission.

If your extension is going to be large, then you will need to go through the Neighbour Consultation Scheme Process.

Neighbour Consultation Scheme

Any planned rear extension that is going to be between four and eight metres for detached houses, or between three and six metres for semi-detached and terraced houses, will need to use the Neighbour Consultation Scheme.

The scheme is linked to a temporarily relaxed building regulations and applies to all larger single-storey extensions that are permitted until 30th May 2019.

The Scheme means that you must notify your local planning authority if you are planning on building a larger rear house extension. Your local planning authority will them notify those who share a boundary with your property so that they have information about your plans. They will then have a period of time where they can object to the plans. Any objections must be received within 21 days of initial notifications. The planning authority must then notify you of whether the project can go ahead.


Planning Permission for Loft Conversions


You will need permission if your loft conversion exceeds the outlined limits and conditions. These limits and conditions include, but are not limited to, the following:

– The conversion is allowed a volume of 40 cubic metres additional roof space for terraced houses and 50 cubic metres for detached and semi-detached houses. When working out whether you require planning permission for a loft conversion, you must also include any previous extensions within the volume allowances

– Any extensions cannot go beyond the ‘plane of the of the existing roof slope of the principal elevation that fronts the highway’

– Your property is not located in a designated area

– Extension cannot extend above the highest part of the roof

– If extending the roof, it must look similar to the rest of the existing materials used.

For more detail of the limits and conditions that you must comply with to be exempt from planning permission for a loft conversion, visit the Planning Portal.


Planning Permission for Renovation Work


DeathtoStock_Medium6It is unlikely that you will need planning permission for interior renovation work, even if your designs include removing or adding an internal wall. You will, however, have to comply with Building Regulations to ensure that any alterations do not affect the safety of your home.

Your internal renovation plans will have to take fire safety, sound insulation, structural support and load bearing walls, and ventilation into account and meet the Building Regulations requirements regarding these. There is more information about Building Regulations and internal walls on the Planning Portal website.
