You Do Not Need A Permit To Conduct The Following Home Improvement Projects

Are you aware of the fact that you do not need planning permission to conduct a variety of home improvement projects? You have implied permission to conduct a variety of projects that are categorized as permitted development.

If you live in a listed structure or a designated area or you have already carried out a wide variety of home improvement projects, your permitted development rights are limited.

Furthermore, you might need to seek a permit for big or extensive projects.

Permitted development rights may be waived altogether in some cases, and as such, to find out whether you need a permit it is recommended that you consult your Local Planning Authority

1. Interior Remodelling Projects

Your permitted development rights in most cases allow you to carry out interior remodeling projects in your home; however, this only applies in cases where the intended improvements do not increase the structure’s overall footprint.

Even though you do not need a permit for the overall project, to work on the electrical system and structural elements, you will however need to seek Building Regulations approval.

2. Adding Or Moving Doors And Windows

Normally, you do not need to acquire a planning permit to add, remove or replace existing windows within the walls of the structure in question. On the other hand, if any terms were connected to the original permit, you may need to seek planning permission.

You can add double glazed windows as per your permitted development rights as long as your structure is not listed; however, you will need to work within the Building Regulations if you are looking to add larger doors or windows. Bay windows are classified as extensions; be sure to remember this.

Provided that any side elevation windows on upper floors are glazed with level 4 or 5 obscured glass, you do not need a planning permit to create an opening for a new door or window. Unless the window opener is over 1.7 metres above the floor of the room the widow is installed, the new windows must be fitted into a non-opening window frame.

3. Garage Conversion

Since the conversion of an internal garage, or any other attached building for that matter, into a living space is not considered to be an increase of your building’s overall footprint, it is allowed under permitted development rights.

You might however need to apply for a change of use when converting a standalone garage.

4. One-Storey Extension Size Limitations

You can embark on a single-storey extension building project without a planning permit provided that:

• The principal elevation is in front of the extension

• Similar materials are used

• The height of the eaves does not exceed 3 metres in cases where any boundaries are within 2 metres.

• The depth of rear extensions should not for a detached house exceed 4 metres in depth or for a terrace or semi-detached house 3 meters in depth.

• The width of the existing building should exceed that of a side extension by more than half. In the case of Article 1(5) Land, like Area Of Outstanding Natural Beauty and Conservation Areas, side extensions are prohibited.

5. Rooflights

Provided that any alterations, such as rooflights, on the roof do not extend more than 15 centimetres from the slope of the roof, you can make them under permitted development rights.

You cannot under permitted development, install rooflights that extend past the roof plane on the elevation right next to a highway.

As previously stated, rooflights cannot be installed on a structure located in an AONB or Conservation Area.

6. Loft Conversions

You can create additional living space in your home without seeking planning approval. The set limit is 40 cubic metres of space according to permitted development limits.

Permitted development rights allow for the construction of dormer windows as a means of increasing loft space headroom. However, this is on condition that they do not protrude forward past the principal elevation of the roof plane, or higher than the existing roof’s highest point.
