Officer’s Report
1.0 THE SITE
1.1 The application site is the residential curtilage of 35 Auburn Road, Onchan, a two-storey semi-detached dwelling located at the north of Auburn Road. The house has a pitched roof and is finished in white paint.
1.2 There is an existing single-story extension and an existing conservatory at the rear elevation to the east elevation of the property. The extension is approx. 3m wide and projecting approx. 2.3m from the rear elevation. It is approx. 2.2m in height. The extension has a flat roof and white paint finish.
1.3 There is also a conservatory next to the extension. The conservatory is approx. 2.9m wide and projecting approx. 2.3m from the rear elevation. It is approx. 1.9m in height. The extension has a flat roof and has glazing as walls.
2.0 THE PROPOSAL
2.1 The proposed work is the erection of a single-storey extension to replace the existing conservatory and adding a lean-to roof on the rear extensions.
2.2 The proposed extension is going to have the following features: o approx. 5.9 wide and projecting approx. 2.3m from the rear elevation; o approx. 2.1m in height; o A mono-pitched roof with concrete roof tiles and two rooflights; o The elevations will be finished to match the existing; o A casement/fixed panel stack window and a double door on the north elevation
3.0 PLANNING HISTORY
3.1 There is no previous application considered materially relevant to this application.
4.0 PLANNING POLICY
4.1 In terms of local policy, the site lies within an area designated as Predominantly Residential Use in the Onchan Local Plan 2000.
4.2 In terms of strategic plan policy, the Isle of Man Strategic Plan 2016 contains the following policies that are considered materially relevant to the assessment of this current planning application:
4.3 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 (m) takes account of community and personal safety and security in the design of buildings and the space around them".
4.4 "8.12.1 Extensions to Dwellings in built-up areas or sites designated for residential use: As a general policy, in built-up areas not controlled by Conservation Area or Registered Building policies, there will be a general presumption in favour of extensions to an existing property

where such extensions would not have an adverse impact on either adjacent property or the surrounding area in general."
4.5 Residential Design Guidance (July 2019) provides advice on the design of new houses and extensions to an existing property as well as how to assess the impact of such development on the living conditions of those in adjacent residential property.
4.6 RDG 4.2 Single Storey Rear Extension sets out some key considerations. These include the impact on the amenities of those in neighbouring properties such as loss of light and/or overbearing. These impacts can be regulated by designing with the right depth (projection) and location. The section also specifically mentioned that terraced/semi-detached dwellings have the potential for the greatest concern due to the potential of "tunnel effect".
4.7 RDG 3.2.2 suggests that flat roofed extensions will normally not be considered acceptable unless the property has existing flat roofed elements and this is particularly where the flat roof would be visible.
4.8 RDG 5 sets out key considerations regarding architectural details. These include window details and external finishing. The general idea is that the extension should have a similar style with the main dwelling for a coherent appearance unless the clash between modern and traditional design can be handled with elegance.
4.9 RDG 7 sets out key considerations regarding the impact on neighbouring properties. These include the potential loss of light/overshadowing, overbearing impact upon outlook and overlooking resulting in a loss of privacy.
5.0 REPRESENTATION
5.1 Douglas Borough Council has no objection to this application (28/07/2020).
5.2 DoI Highway Services states there is no highway interest in this application (22/07/2020).
6.0 ASSESSMENT
6.1 The main concerns for this application are its impact on the character and landscape of the area and its impact on the amenities of the neighbours.
6.2 The extension is at the rear of the property. It is not visible by the public and therefore it should not stand out around the neighbours. Therefore, there is no adverse impact on the character or landscape of the area.
6.3 There is no additional concern regarding the loss of light and overbearing impact upon the outlook of neighbouring properties as the height of the proposed extension is no higher than the existing extension.
6.4 The west elevation has been replaced with a wall. Comparing this to the previous glass windows, there is an improvement in preserving the privacy of the neighbouring property.
7.0 CONCLUSION
7.1 The proposal is considered to comply with General Policy 2 of the Strategic Plan and Residential Design Guide Section 4, 5 and 7. Therefore, it is recommended for an approval.
