Officer’s Report

1.0 THE SITE - 1.1 The application site is the residential curtilage of 9 Manor View, Douglas, a two-storey detached dwelling located on the northeast of Manor View. The house has a pitched roof.

There is an existing conservatory on the rear elevation. There is also an existing extension on the southeast elevation of the property.

2.0 THE PROPOSAL - 2.1 The proposed work is the demolition of the existing conservatory and the erection of a rear extension. It has the full width of the main dwelling and it will have a mono-pitched roof.

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 in the Area Plan for the East. - 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".

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 3.2 Potential Visual Impact of an Extension upon the Existing House states a pitched roof is preferred to a flat roof, especially when it's publicly visible. However, an exception can possibly be made when the existing property has a flat/low pitched roof design. - 4.7 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". - 4.8 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 on this application (04/12/2020). - 5.2 DoI Highway Services states there is no highway interest in this application (04/12/2020).

6.0 ASSESSMENT - 6.1 The main concerns for this application are its impact on the character and street scene of the area and the amenities of the neighbours. - 6.2 The single-storey extension is on the northeast of the property. It is designed in a similar style as the main dwelling. Therefore, the design is considered acceptable. - 6.3 The extension is single storey and the site is at the same level and is aligning northwestsoutheast with the neighbouring properties. The elevation that will face No. 7 has no windows. The rear has windows/door and is approx. 8m to the nearest property. There is a window that is partially visible but this is likely the garage of the property. The elevation that faces No. 9 has no windows/doors. There is an existing fence (approximately 2 metres) around the boundary and that the vantage point already exists (although would be from in the garden), it is not considered that this is an unacceptable level of overlooking.

7.0 CONCLUSION - 7.1 The proposal is considered to comply with General Policy 2 of the Strategic Plan and Residential Design Guide Section 3, 4, 5 and 7. Therefore, it is recommended for an approval.
