PPS 7 Addendum Residential Extensions and Alterations·Page 11·2.11
Ancillary use condition and neighbour impact
The Department must be satisfied that proposed accommodation will remain ancillary to the main dwelling, with careful consideration given to impact on neighbouring properties. Permissions will be subject to conditions restricting use to ancillary residential purposes only.
In all cases the Department will need to be satisfied that the proposed accommodation will remain ancillary to the main residential property and careful consideration will be given to the impact of proposals on neighbouring dwellings. Where permission is granted it will be subject to a condition that the extension will only be used for ancillary residential purposes in connection with the main dwelling, and not as a separate unit of accommodation.
