Northern Ireland Planning Service

PPS 7 (Addendum): Residential Extensions and Alterations
Preamble

The Department of the Environment is responsible for planning control in Northern Ireland. The Planning Service, an Agency within the Department, administers its development control and development plan functions.
The Department has a statutory duty, laid down in Article 3 of the Planning (Northern Ireland) Order 1991, to formulate and co-ordinate policy for securing the orderly and consistent development of land and the planning of that development. The Department is required to ensure that such policy is in general conformity with the Regional Development Strategy.
The Department’s planning policies are normally issued through Planning Policy Statements (PPSs) and PPS 1 ‘General Principles’ advises that:
“Planning Policy Statements set out the policies of the Department on particular aspects of land-use planning and apply to the whole of NorthernIreland. Their contents will be taken into account in preparing development plans and are also material to decisions on individual planning applications and appeals.”
This document is an Addendum to PPS 7 ‘Quality Residential Environments’ and must be read in conjunction with the policies contained within that PPS.  The Addendum provides an additional planning policy for the extension and/or alteration of a dwellinghouse or flat, including those in multiple occupancy. It embodies the Government’s commitment to sustainable development and the Quality Initiative. However, it should be noted that unlike the other policies of PPS 7, the policy contained in this Addendum will apply to all dwellinghouses or flats throughout the Region, including single dwellings in the countryside.
Proposals for a domestic garage or an outbuilding, or other built development ancillary to a residential property will also be considered under the provisions of this Addendum.
Furthermore, the policy approach and associated guidance contained within this document will be useful in assessing proposals for extensions and/or alterations to other residential uses, such as, residential / nursing homes, hostels and holiday accommodation.
This Addendum to PPS 7 supersedes policy HOU 16 ‘House Extensions’ of the Planning Strategy for Rural Northern Ireland. Where this policy is referred to elsewhere in the Planning Strategy, the policy and guidance in this Addendum will take precedence.
This policy document has been subject to an equality impact screening exercise in line with the statutory obligation contained in Section 75 of the Northern Ireland Act 1998. The outcome of this exercise indicates that the document is unlikely to have any significant adverse implications for equality of opportunity or community relations.
Nothing in this document should be read as a commitment that public resources will be provided for any specific project. All proposals for expenditure by the Department are subject to economic appraisal and will also have to be considered having regard to the overall availability of resources.
