Officer’s Report
1.0 SITE 1.1 The site is the residential curtilage of 16 Cronk Avenue, Onchan - a semi-detached two storey dwelling with attached garage. The front of the dwelling is set back from the roadside with a modern paved driveway over most of the frontage and a small grassed garden area bounded to the adjoining 14 Cronk Avenue by hedging.
1.2 The site is slightly lower in level than No.18 to the north, which is 8m from the main gable wall although the respective garages are only 4.5m apart. It slopes gently towards No.14 to the south. The design of the dwelling is fairly uniform with the flat roofed garage a common feature of the street scene, and a mixed finish of red brick on the ground floor and painted render on the first floor. The windows are casement uPVC. The front garden is also a feature throughout the street scene.
2.0 PROPOSAL 2.1 The proposal is for a two storey extension to the side of the dwelling. Initially, the removal of the remaining grass area at the front of the site was proposed but following discussions between the case officer and the applicant, amended plans were received removing this part of the application. The proposal therefore is for the extension only.
2.2 The extension would follow the same design as the existing in terms of wall finish and windows/tiling. The extension would be positioned roughly where the existing garage on the site is, with a new garage protruding by approximately 1.5m from the existing front elevation with a single storey mon pitch roof to match the main dwelling. Set back 2.7m from the front of this garage and front door porch would be the front elevation of the first floor part of the extension. The first floor of the rear elevation would sit flush with the main dwelling, although it is proposed that the roof ridge be set 0.3m lower. The ground floor of the rear extension would also feature a mono pitch roof extending from the main rear elevation by 1.2m.
2.3 The gable wall of the dwelling would feature a side door into the kitchen and a small window from the garage. Both the front and rear elevations would feature a bedroom window on the first floor, with a ground floor rear window from the proposed kitchen. These windows would follow the aperture size and design of the existing elsewhere on the dwelling.
3.0 PLANNING HISTORY 3.1 In terms of planning history on the site, there is one past application for the extension of the original driveway area, the paving of the driveway and removal of much of the grass/planted area. It was approved (10/00648/B).
4.0 PLANNING POLICY 4.1 The proposal site is in an area designated in the Onchan Local Plan 2000 as Residential Use.
4.2 Given the land use designation, General Policy 2 (in part) of the Isle of Man Strategic Plan 2016 applies "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; (h) provides satisfactory amenity standards in itself, including where appropriate safe and convenient access for all highway users, together with adequate parking, servicing and manoeuvring space; (i) does not have an unacceptable effect on road safety or traffic flows on the local highways;"

Paragraph 8.12.1 of the Strategic Plan (IOMSP) is also useful when it comes to assessing this application: "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 existing property where such extensions would not have an adverse impact on either adjacent property or the surrounding area in general."
5.0 REPRESENTATIONS 5.1 Prior to the submission of amended plans, Onchan Commissioners recommended the application be approved (08.01.19).
6.0 ASSESSMENT 6.1 The key considerations in the assessment of this application are, the impacts on the visual amenity of the area and the street scene, the impacts on neighbouring dwellings residential amenity, and the parking provision on the site.
6.2 Visual Impact
6.2.1 When viewed from Cronk Avenue both north and south, the visual impact of the extension would be reduced by the set back nature of the front elevation and the use of mono pitch roofs to break up the appearance somewhat. The use of matching finishes would also ensure that the extension successfully fits with the existing building and the street scene as a whole.
6.2.2 It is not regarded that there would be any negative visual impact resulting from the proposal as the extension would appear secondary to the main dwelling and is not of an unacceptable scale, thus complying with GP2 (b,c,g) and Paragraph 8.12.1 of the IOMSP.
6.3 Impact on Neighbour Amenity
6.3.1 Firstly, overshadowing is assessed as the extension would bring the main body of the dwelling approximately 3m closer to No.18 to the north. The level of shadowing can be estimated by the following; A simple check can be undertaken by drawing a section in a plane perpendicular to the main face of the building affected. If the potential obstructing extension subtends an angle to the horizontal, at a height 2 metres from ground level, less than 45° then there will still be the potential for good daylight to the interior. As No.18 is to the north of the dwelling and the extension, there would be no risk of overshadowing resulting from the proposal.
6.3.2 Additionally, there are no windows on the gable of No.18, and the only window opening proposed from the gable of No.16 is a small ground floor garage window. The additional windows on the front and rear elevations are in excess of 20m from the nearest neighbouring elevation which they face - 20m is the general rule of thumb for which apertures within this distance could cause overlooking into or onto neighbouring habitable rooms or gardens.
6.4 Parking
6.4.1 The extension would reduce the parking area at the front of the dwelling from approximately 3 spaces to 2 spaces. This would still meet the parking standards in Appendix 7 of the IOMSP.
7.0 CONCLUSION 7.1 In summary, the proposal for a two storey extension complies with the aforementioned IOMSP policies and is recommended for approval.
