Agenda item

To consider an application for a first floor rear extension over existing single storey rear extension.

The Committee considered a report seeking planning permission for a first-floor rear extension above part of an existing single-storey rear extension. It was noted that the application had been referred to the Committee because the applicant was related to a member of Council staff, in accordance with the Council's Constitution.

The Senior Planning Officer advised that the proposal related to a property within a conservation area and explained that the extension would occupy only part of the existing flat-roofed rear extension, with the remaining section retained at single-storey level.

The Committee was informed that the Council's Conservation and Heritage Officer had raised no objections, concluding that, although the proposal would introduce some visual imbalance to the rear of the semi-detached property, it would preserve the character and appearance of the conservation area.

The Committee was advised that the proposal would have an acceptable impact on neighbouring residential amenity, with no significant adverse effects arising from overlooking, loss of light or overbearing impact. As there was no increase in the number of bedrooms, no additional parking assessment was required.

Members noted that the submitted climate statement demonstrated compliance with relevant building regulations for energy and water efficiency. The proposal was considered to comply with the relevant planning policies, and planning permission was therefore recommended for approval.

It was also noted that Councillor Julie Ashley-Wren, having declared an interest in the item, did not take part in its consideration.

Following the questions, a motion to proceed to the debate and vote was proposed and seconded.

A vote was taken and It was RESOLVED that planning permission be GRANTED subject to the conditions set out below and delegated authority be given to the Director of Planning and Regulation in consultation with the Chair of the Planning and Development Committee, to amend or add to the conditions subject to which the permission would be granted, where such amendments or additions would satisfy the relevant national policy tests and would most effectively deliver the development which the Committee has resolved to approve.

1 The development hereby permitted shall be carried out in accordance with the following approved plans:

1003-02-EBP; 1003-01-SLP; 1003-03-PBP; 1003-04-EPE ISSUE C; 1003-05-EPE ISSUE C;

2 The development hereby permitted shall be begun before the expiration of three years from the date of this permission.

3 The external materials used in the development to which this permission relates shall be those detailed on the approved plans and in the accompanying planning submission documents unless otherwise agreed in writing by the local planning authority.

4 No access shall be provided to the roof of the existing single storey extension by way of windows, doors or staircases and the roof of the existing extension shall not be used as a balcony or sitting out area.

The Council has acted Pro-Actively for the following reason:-

1 Planning permission has been granted for this proposal. The Council acted pro-actively through early engagement with the applicant at the pre-application stage which led to improvements to the scheme. The Council has therefore acted pro-actively in line with the requirements of the National Planning Policy Framework and in accordance with the Town and Country Planning (Development Management Procedure) (England) Order 2015.

2 Community Infrastructure Levy

Stevenage Borough Council adopted its revised Community Infrastructure Levy (SCIL2) Charging Schedule at Full Council on 10 June 2026 and started implementing SCIL2 on 22 July 2026.

This application may be liable for CIL payments and you are advised to contact the CIL Team for clarification with regard to this. If your development is CIL liable, even if you are granted an exemption from the levy, please be advised that it is a requirement under Regulation 67 of The Community Infrastructure Levy Regulations 2010 (as amended) that CIL Form 6 (Commencement Notice) must be completed, returned and acknowledged by Stevenage Borough Council before building works start. Failure to do so will mean you risk losing the right to payment by instalments and a surcharge may be imposed. NB, please note that a Commencement Notice is not required for residential extensions if relief has been granted. Stevenage's adopted SCIL2 Charging Schedule and further details of CIL can be found on the Council's webpages at www.stevenage.gov.uk/CIL or by contacting the Council's CIL Team at CIL@Stevenage.gov.uk.

5 Biodiversity Net Gain

Applications where Biodiversity Net Gain is not required as application is for householder permission. The effect of paragraph 13 of Schedule 7A to the Town and Country Planning Act 1990 is that planning permission granted for the development of land in England is deemed to have been granted subject to the condition "(the biodiversity gain condition") that development may not begin unless:

a) a Biodiversity Gain Plan has been submitted to the planning authority, and

b) the planning authority has approved the plan.

The planning authority, for the purposes of determining whether to approve a Biodiversity Gain Plan if one is required in respect of this permission would be Stevenage Borough Council. There are statutory exemptions and transitional arrangements which mean that the biodiversity gain condition does not apply.

Based on the information available this permission is considered to be one which will not require the approval of a biodiversity gain plan before development is begun because the following statutory exemption or transitional arrangement is considered to apply.

1.    Development which is subject of a householder application within the meaning of article 2(1) of the Town and Country Planning (Development Management Procedure) (England) Order 2015. A "householder application" means an application for planning permission for development for an existing dwellinghouse, or development within the curtilage of such a dwellinghouse for any purpose incidental to the enjoyment of the dwellinghouse which is not an application for change of use or an application to change the number of dwellings in a building.

Where the local planning authority considers that the permission falls within paragraph 19 of Schedule 7A to the Town and Country Planning Act 1990, the permission which has been granted has the effect of requiring or permitting the development to proceed in phases. The modifications in respect of the biodiversity gain condition which are set out in Part 2 of the Biodiversity Gain (Town and Country Planning) (Modifications and Amendments) (England) Regulations 2024 apply.

Biodiversity gain plans are required to be submitted to, and approved by, the planning authority before development may be begun, and, if subject to phased development, before each phase of development may be begun.

If the onsite habitat includes irreplaceable habitat (within the meaning of the Biodiversity Gain Requirements (Irreplaceable Habitat) Regulations 2024) there are additional requirements for the content and approval of Biodiversity Gain Plans. The Biodiversity Gain Plan must include, in addition to information about steps taken or to be taken to minimise any adverse effect of the development on the habitat, information on arrangements for compensation for any impact the development has on the biodiversity of the irreplaceable habitat. The planning authority can only approve a Biodiversity Gain Plan if satisfied that the adverse effect of the development on the biodiversity of the irreplaceable habitat is minimised and appropriate arrangements have been made for the purpose of compensating for any impact which do not include the use of biodiversity credits.
