1.0 THE SITE
==== PAGE 2 ====
23/00863/B Page 2 of 4
1.1 The application site comprises a 3-bedroom detached bungalow and its associated curtilage at the south-eastern end of a cul-de-sac; Birch Hill Avenue, Onchan. The property benefits from a generous rear garden bordering Onchan's Shoprite supermarket to the south- east, and includes a front driveway, front garden area and attached garage.
2.0 THE PROPOSAL 2.1 Retrospective planning permission is sought for the erection of a flat roofed single- storey side/rear extension. It is understood that the extension was constructed in 2017 following demolition of the sun room/greenhouse previously in situ in 2015. The extension is physically attached to the flat roofed garage and mirrors its design, scale and built form. Internally, the extension has facilitated a new dining room, utility and shower room. The resultant garage and side/rear extension effectively comprises a flat roofed wraparound to the property.

6.0 ASSESSMENT 6.1 The main issues to consider in the assessment of this planning application are as follows:
6.2 PRINCIPLE 6.2.1 The site falls within the settlement boundary of Onchan and an area zoned for residential development, where there is a general presumption in favour of extensions to existing properties provided such development would not have an adverse impact on either adjacent properties or the surrounding area in general.
6.3 DESIGN AND VISUAL IMPACT 6.3.1 The extension as constructed mirrors the design, form and scale of the attached flat roofed garage, whilst having been finished in matching white painted render. The most recently published Residential Design Guide (2021) does seek to ensure greater scrutiny over the development of flat roofed extensions to residential properties, noting the rise in such additions being used across the Island and their varying levels of success. In this instance however, it is recognised that the extension is not visible within the context of the streetscene and therefore poses no material impact upon its character. Likewise, the extension assimilates well with the flat roofed garage which was previously in situ prior to the works being undertaken, and therefore the development does not appear incongruous in the context of the dwelling's vernacular.
6.3.2 On balance therefore, the development as constructed is considered to be acceptable from a design and visual impact perspective, whilst having delivered an enhanced level of internal accommodation for the property and amounting to a more efficient use of the site. The proposals are therefore considered to be acceptable in this regard, in compliance with General Policy 2 (b) & (c).
6.4 NEIGHBOURING AMENITY 6.4.1 Due to the modest scale and siting of the extension within the site, together with its relationship with neighbouring properties, it is not considered that the development has posed a materially harmful impact upon residential amenity, in compliance with General Policy 2 (g).
7.0 CONCLUSION 7.1 The development is acceptable in terms of its form, mass and design by having provided suitable additions to an existing residential property and as such comply with Strategic Policy 5, Spatial Policy 2, General Policy 2 and Environment Policy 42 of the Isle of Man Strategic Plan (2016). The application is therefore recommended for approval.
