Officer’s Report
1.0 THE SITE
1.1 The application site relates to Strathallan Cliff House, which is a large, detached dwelling, standing in spacious grounds, and located on the south side of Strathallan Road, Onchan. The dwelling has a two-storey side wing attached to its east side which currently has a double casement window facing south in the rear elevation.
1.2 Vehicular access to the site is derived from Strathallan Road.
2.0 THE PROPOSAL
2.1 Proposed is the installation of a raised patio area, and the installation of new external patio doors in place of the double casement window in the two-storey side wing facing south in the rear elevation. The patio area would measure approx. 4.0m deep x 3.5m wide. It would stand above existing ground level by approx. 0.565m. The decked area would be bounded by 1.2m high glazed balustrades around its sides and would have a set of steps down to the rear garden approx. 0.970m wide. The appearance of the external walls following the installation of the patio doors would be made good to match the existing white render wall finish.
3.0 PLANNING POLICY 3.1 The site lies within an area designated on the Area Plan for the East (2013) as Predominantly Residential.
3.2 The site is not in a Flood Risk Area or Conservation Area and none of the buildings or trees on site is Registered.
3.3 As such, the following parts of the Strategic Plan are relevant:
General Policy 2: "Development which is in accordance with the land-use zoning and proposals in the appropriate Area Plan and with other policies of this Strategic Plan will normally be permitted, provided that the development:
(b) respects the site and surroundings in terms of the siting, layout, scale, form, design and landscaping of buildings and the spaces around them; (c) does not affect adversely the character of the surrounding landscape or townscape; (g) does not affect adversely the amenity of local residents or the character of the locality; (i) does not have an unacceptable effect on road safety or traffic flows on the local highways; (k) does not prejudice the use or development of adjoining land in accordance with the appropriate Area Plan;".
3.4 Environment Policy 22 (in part):
Development will not be permitted where it would unacceptably harm the environment and/or the amenity of nearby properties in terms of: (iii) vibration, odour, noise or light pollution;

4.3 21/00786/B - Creation of pedestrian access and installation of gate (part retrospective) at Strathallan Cliff House, Strathallan Road, Onchan, IM2 4PN - Approved - 17.11.2021.
5.0 REPRESENTATIONS 5.1 Highway Services - Comments received - 29/9/23 - Highway Services HDC comments that it has no highways interest in the proposal. 5.2 Onchan Commissioners - Received 5/10/23 - The Commissioners recommend the application be approved for planning purposes only.
NEIGHBOUR REPRESENTATIONS 5.4 No representations had been received by the Report drafting stage.
6.0 ASSESSMENT 6.1 The fundamental issues to consider in the assessment of this planning application are:
(i) visual impact of the proposed development; (GP2 b, c) (ii) the impact upon the amenities (overlooking, loss of light; over bearing impact, (privacy and visual amenity) of the neighbouring properties. (GP2 (g) (iii) impact of the revisions to the access on highway safety. (GP2 (i)
6.2 Visual impact 6.2.1 The proposed works involve the extension via the provision of a raised decked area to the rear of the eastern side wing of the dwelling, and alterations to the dwelling to install patio doors. The works would be on the south facing elevation of the house with a view out towards Douglas Bay.
6.2.2 The installation of the decked outdoor patio area would measure approx. 4.0m deep x 3.5m wide, and would stand above existing ground level by approx. 0.565m. The decked area would be bounded by 1.2m high glazed balustrades around its sides and would have a set of steps down to the rear garden approx. 0.970m wide. The siting of the decked area on the south side of the dwelling would result in it being screened from any public views from Strathallan Road by the dwelling; and, it would be sufficiently separated from the adjoining dwelling to the east at The Laurels for it to have no impact on views from the rear garden area and side elevation of this property. Overall, these changes are considered to be relatively minor in the context of this sizeable dwelling and accord with the provisions of Policy GP2 b, and c of the Adopted Island Development Plan 2016.
6.3 Neighbours amenity 6.3.1 The outdoor raised deck of the patio would be sited to the rear of the dwelling and well away from the neighbouring dwelling at The Laurels. The host dwelling would screen the patio area from any views from the west and owing to the large size of the rear garden area to the rear/south of the dwelling it would appear as an insignificant feature in respect of any views from Tremissary House, which itself is located at a lower level than Strathallan Cliff House.
6.3.2 Overall, with regard to the potential impact of the development on neighbouring residents amenities, the proposed development is considered to be acceptable and accords with the provisions of Policy GP2 (g) and (h), of the Adopted Island Development Plan 2016.
7.0 CONCLUSION 7.1 For the above reasons, it is concluded that the planning application would result in a visually acceptable form of development that would not harm the use and enjoyment of neighbouring properties; or, give rise to issues of highway safety. As such, the proposed development is acceptable and would comply with the principles of General Policy 2, Environment Policy 22 of the Isle of Man Strategic Plan 2016, and is recommended for approval.
