PRIOR APPROVAL EXTENSION

NORWICH, NORFOLK

Make the most of the Larger Home Extension Scheme

What is permitted development?

Permitted development is a type of pre-approved permission to build, which allows you to bypass the main planning process. You should still apply to your council for a lawful development certificate to prove your development is within the conditions provided, but if your plans fall within the scheme, it can save time and potential complications over putting in a full planning application.

Does my single storey rear extension qualify?

To take advantage of this extra allowance under permitted development, you’ll need to ensure your plans extend no more than 8 metres (for a detached property) or 6 metres (for all other properties) from the rear elevation of the original house, as it stood on 1 July 1948.

Even if you haven’t built a rear extension yourself, your permitted development rights may have already been used up if a previous owner added to the property. If you think this might be the case, please call us and we can check on your behalf.

The development must also comply with other conditions that apply to all rear extensions allowed under permitted development. These include:

No more than half the area of land around the original house (as it stood on 1 July 1948) should be covered by buildings.
The maximum height of the extension is 4 metres, as measured from the highest point of natural surface ground. The maximum height reduces to 3 metres if the extension is within 2 metres of a boundary.
Construction materials must be similar in appearance to those used for the existing house. No balconies, verandas, raised platforms or chimneys are included.
As with any other kind of permitted development, this scheme does not apply to homes in conservation areas, flats or maisonettes.

When do I have to build by?

In order to benefit from this scheme, your extension must be fully completed on or before 30 May 2019. You’ll need to notify the council in writing once your project is finished.

Remember that you'll need to leave up to 42 days for your application to be approved under the Neighbour Consultation Scheme, while sourcing surveyors and contractors also takes time, so you should start planning soon if you're interested in making the most of this increased allowance.

You can easily get the ball rolling with our affordable, fast turnaround planning packages, which include designs, floor plans, elevations and 3D renders.

What is the Neighbour Consultation Scheme?

This is the approval process for extensions built under the Larger Home Extension Scheme.

Once you provide the detailed plans for your project to the council (we can help you do this!), they will notify any adjoining owners or occupiers to your development (i.e. your neighbours) and invite them to raise any objections within a 21 day period.

If no objections are received, and the development complies with all of the relevant criteria under permitted development rights and the Larger Home Extension Scheme, you’ll be notified by the council within a 42 day period and may start building, potentially under certain additional conditions.

If your application is refused, you can appeal, and we'll advise you on the best next steps.

Case Study: 22/03758/HHE | Erection of a single storey rear extension to detached dwelling (Utility and toilet extension). Dimensions 8.00 metres beyond the rear wall, 3.50 metres maximum height and 2.40 metres high to the eaves. | 7 Glynmorlas St Martins Oswestry Shropshire SY11 3EE

This application seeks a legal determination that the following proposed works within the domestic curtilage of the above dwelling house would be classed as ‘permitted development’ under the Town and Country Planning (General Permitted Development) Order 2015, Schedule 2, Part 1 (Class A.(g)): -
- Erection of a single storey rear extension to detached dwelling

The property is a detached dwelling with no near neighbours to the northwest of St Martins. it is located in a valley characterised by sporadic residential properties along narrow country lanes. The scheme complies with the delegation to Officers as set out in Part 8 of the Shropshire Council Constitution.

The proposed development involves the erection of a single storey extension to the rear of the property. Therefore, Schedule 2, Part 1, Class A.(g) is the relevant part of the legislation. As such, the proposal has been considered against the amended criteria to allow for the erection of larger extensions as follows: -
6.1.2 4.—(1) In Part 1 of Schedule 2 (development within the curtilage of a dwellinghouse), Class A is amended as follows:
(g) for a dwellinghouse not on article 2(3) land nor on a site of special scientific interest, the enlarged part of the dwellinghouse would have a single storey and—
(i)extend beyond the rear wall of the original dwellinghouse by more than 8 metres in the case of a detached dwellinghouse, or 6 metres in the case of any other dwellinghouse, or
(ii)exceed 4 metres in height;”
A.4.—(1) The following conditions apply to development permitted by Class A which exceeds the limits in paragraph A.1(f) but is allowed by paragraph A.1(g).
(2) Before beginning the development the developer shall provide the following information to the local planning authority—
(a)a written description of the proposed development including—
(i)how far the enlarged part of the dwellinghouse extends beyond the rear wall of the original dwellinghouse;
(ii)the maximum height of the enlarged part of the dwellinghouse; and
(iii)the height of the eaves of the enlarged part of the dwellinghouse;
(b)a plan indicating the site and showing the proposed development;
(c)the addresses of any adjoining premises;
(d)the developer’s contact address; and
(e)the developer’s email address if the developer is content to receive
communications electronically.

In this case the proposal is for a single storey extension projecting from the rear of the property in total by 8m. The extension will have a maximum height of 3.5m and 2.4m to the eaves. Exact material details have not been specified however the requirement that the materials are to match the original building as much as
possible will be included on the decision notice.

The changes to the regulations require the local planning authority must, when considering the impact referred to in sub-paragraphs (7)—
(a) take into account any representations made as a result of the notice given under paragraph (5); and
(b) consider the amenity of all adjoining premises, not just adjoining premises which are the subject of representations.

No objections have been received from any of the properties notified of the proposal and therefore prior approval is not required in respect of the impact of the proposed development on neighbouring properties.
In view of the above it is confirmed that the details submitted with the application demonstrate that the conservatory will be exempt from requiring planning permission as these works comply with the requirements of Class A.(g) of Schedule 2 Part 1 of the Town and Country Planning (General Permitted
Development) Order 2015.

Planning permission will not be required for the proposed development as it meets the criteria set out in Schedule 2, Part 1, Class A.(g) of the Town and Country Planning (General Permitted Development) Order 2015. Further to the approval En-Plan have assisted in producing Building Regulations Plans ot deal with the technical side of the project.
