Application No.: 15/01173/B Applicant: Mumba Holdings Proposal: Re-instatement of boundary bank, erection of gardener's store with viewing platform, erection of garden shed and landscaping Site Address: Thie Ny Strooan Hillberry Green Douglas Isle of Man IM2 6DE Case Officer : Mr Edmond Riley Site Visit: 10.11.2015 Expected Decision Level: Officer Delegation
1.0 THE APPLICATION SITE - 1.1 The application site is the residential curtilage of a detached property known as Thie Ny Strooan, which is located within Hillberry Green, Douglas. The previously existing dwelling to the west of the site has been demolished and a replacement dwelling was recently under construction, although what stage the building works are currently at is unknown. - 1.2 A watercourse runs through the site from north to south. The eastern half of the site rises towards the A18 Mountain Road and has mature tree planting within it. The section of the site closest to Mountain Road is more open but also has tree planting within it, focused mostly around the edges. The boundary with Mountain Road was until recently formed by a Manx sod bank; this has been removed, presumably in anticipation of the grant of planning approval for a previous planning application that was subsequently withdrawn. - 1.3 Behind this boundary line sits an almost complete indoor tennis court. - 1.4 To the southeast of the site is a cluster of three detached dwellings, Gleneagles, Glen Kella and Glen Nook, Mountain Road, Douglas. These properties share an access from the Mountain Road which is situated to the immediate north of Glen Kella and adjoins the southern boundary of the site. A brick wall runs along the boundary. - 1.5 To the north are a number of detached dwellings which form a cul-de-sac development known as The Laurels. These properties are accessed from Mountain Road via Hailwood Avenue. Numbers 18, 19, 20, 22 and 23 have boundaries that adjoin or face directly onto the application site.
2.0 PLANNING HISTORY - 2.1 The site has a broad and relevant planning history. Replacement dwellings were approved under successive applications submitted in 2012 (PAs 12/00545/B and 12/001279/B), though it is understood that it is the latter that has been implemented. - 2.2 Also of relevance is the pair of approvals relating to the erection of the tennis court within the site, which was originally approved at appeal under PA 13/00423/B, and latterly approved under delegated authority to PA 14/00154/B; this subsequent application sought approval for an amended
design, incorporating the following differences as outlined in the officer report into that latter application:
2.3 Following these two approvals, two applications were submitted but withdrawn before a decision could be issued. PA 15/00688/B sought approval for "Erection of boundary fencing and landscape design", while PA 15/00988/B sought approval for "Erection of a roadside gardeners store with roof top viewing platform, greenhouse and garden shed". In view of the fact that some elements of both applications were potentially unacceptable, and some acceptable, both applications were withdrawn. The current application has been submitted in an attempt to gain approval for all those elements considered likely to be acceptable.
3.0 THE PROPOSAL - 3.1 Full planning approval is now sought for the erection of a viewing platform and a garden shed, in addition to landscaping works and tree-planting throughout the site. Also proposed is a turning area for maintenance and emergency vehicles (which is identical in floor area to an already approved such area, but has been squared off), while a pedestrian access onto the Mountain Road is also proposed. Finally, the re-instatement of the Manx bank is proposed, with a hedgerow behind (i.e. between the bank and the building). The species comprising that hedgerow have yet to be determined. - 3.2 The vehicular access would have a pair of short stone walls returning into the site, with timber gates set on gateposts at the end of those walls. The pedestrian access gate would also be timber and is shown set within the hedging. The turning area would be edged with granite although the material itself is not immediately clear from the submitted details albeit that it would be intended to tie in with that which surrounds the building. - 3.3 The viewing platform would provide a small kitchen, small hand tool store and WC, all to provide welfare facilities for the gardeners, with space above to view the TT course. It would be entirely clad in timber, with access to the platform above provided by a partially-curved staircase formed of metal. The gardeners shed would be timber clad and an illustrative drawing shows it would be flat-roofed, with the site plan and supporting letter identifying its location within existing trees; as the application site is the residential curtilage of Thie ny Strooan, and the shed would be 15sqm in size, this could actually be built under permitted development rights.
4.0 PLANNING POLICY - 4.1 In terms of land use designation the application site is part zoned as Low Density Housing in Parkland and part zoned as Predominantly Residential use under the Isle of Man Planning Scheme (Douglas Local Plan) Order 1998. The proposed works are located within the part of the application site that is zoned as Predominantly Residential use.
4.2 In terms of strategic plan policy, the Isle of Man Strategic Plan contains two policies that is considered specifically material to the assessment of this current planning application. General Policy 2 states (in part): "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:
4.4 Whilst the proposed works are some distance from the watercourse, the watercourse is within the site and, as such, Environment Policy 7 should be noted: "Development which would cause demonstrable harm to a watercourse, wetland, pond or dub, and which would not be overcome by mitigation measures will not be permitted. Where development is proposed which would affect a watercourse, planning applications must comply with the following criteria:
5.1 Highway Services of the Department of Infrastructure offered no objection to the application on 11th November 2015, commenting as follows:
"Highways do not oppose the landscaping of the approved emergency/maintenance access. Highways would recommend that the pedestrian access is blocked up."
5.2 Douglas Borough Council offered no objection to the application on 6th November 2015.
6.1 The proposal, despite the large building under construction on the site and also the long period over which the construction works that have been undertaken, are actually fairly minor in scale relative to the works still ongoing. The key issues are the impact of the proposed works on highway safety, visual amenity of the site in what is a very prominent position, and the living conditions of neighbours.
6.2 In the first instance, it is considered that the impact from the shed would be minimal. It cannot be ignored that a shed of the size proposed could be built under permitted development rights, and so this assessment can only extend so far in respect of its consideration of this element of the proposal. In any case, its size, form and materials are considered unobjectionable when considered against parts (b), (c) and (g) of General Policy 2. - 6.3 From an aesthetic point of view, the viewing platform would be a welcome addition to the appearance of the site. It is not especially large and would in any case sit behind and amongst the natural landscaping. As much as it could be seen, it would neatly tie in with the finishes of the nearly complete tennis court and is unobjectionable when considered against parts (b), (c) and (g) of General Policy 2. - 6.4 The re-instatement of the Manx bank is welcome. Its loss (without planning approval) was of significant concern to local residents and also to some extent to officers as well since, while this may not be an especially traditional feature within a town, it is a key and strong feature of this part of the Mountain Road, and its loss was therefore likely to have been unacceptable. This part of Douglas is not characterised by its built development and traditional countryside features would therefore be welcome here. This element of the proposal is therefore considered to be acceptable and fully in accordance with parts (b) and (f) of General Policy 2. - 6.5 The landscaping proposed throughout the site, in the form of some low level walls and treeplanting, is considered to be helpful in strengthening this character by using, in the main, natural materials in the form of stone and timber and self-evidently natural features in the form of trees and grassland. It is noted that the trees to be planted adjacent to the nearby dwelling of 18 The Laurels would be to a maximum of 4m in height. While concern on this matter from the residents thereof in the past is noted and understood, it must be remembered that the Planning System can rarely be too heavily involved in controlling trees and tree-planting: the planting of a tree is not "development". - 6.6 A condition requiring that the trees in this area be kept to 4m in height or below would be appropriate to attach in this instance in view of the concern raised previously, although it is arguable as to whether or not such a condition would be attached had the agent to the application previously indicated their contentment with such a condition (and the fact that the proposed landscape plan explicitly states this). - 6.7 A similar condition with respect to the hedgerow to the highway-facing side of the site was also considered; the drawing submitted shows that the hedging would be a maximum of 3.3m in height but would grade down in height to a 1.7m at the point it ends at the common boundary of 18 The Laurels. This is considered to be acceptable and as it is explicitly stated on the submitted drawings a condition detailing this would therefore not be necessary. - 6.8 It is also considered that a condition requiring full details of the planting programme be submitted to and approved in writing by the Department would not be inappropriate. This, apart from anything, will enable the trained Foresters within the Department to provide professional advice on the most appropriate species and locations for those within the site. - 6.9 Turning to the highway safety impacts, it is noted and welcomed that the turning area remains intended for use for emergency and maintenance vehicles only. The condition attached that previously made this requirement on the earlier approved design would be appropriate again on this occasion, and again is something with which the agent to the application has indicated their contentment. The visual impact of this area will be suitably limited because of its size and will, in any case, be largely hidden from public view by the bank, hedge and gates proposed. A condition requiring a sample of the material to be laid on this area would be appropriate. - 6.10 The proposed pedestrian access has in the past proved a little controversial, but it is not considered that this in itself could form a standalone reason to refuse the application. The access is
for personal use of the applicant, who enjoys walking in the nearby countryside, and though providing a pedestrian access onto a road without a pavement is not ideal, it must be remembered that the applicant would be the sole user of this and any risk associated with its use will be borne by him alone. Highway Services' support of the proposal overall is noted and, while they express a preference for the pedestrian access to be blocked up, this is not judged reason enough to refuse the application. It is therefore considered the proposal is in accordance with parts (h) and (i) of General Policy 2.
7.1 Subject to the various conditions discussed, it is recommended that the application be approved. - 8.0 INTERESTED PERSON STATUS
8.1 By virtue of the Town and Country Planning (Development Procedure) (No 2) Order 2013, the following persons are automatically interested persons:
Recommendation Recommended Decision: Permitted Date of Recommendation: 23.11.2015 Conditions and Notes for Approval: C : Conditions for approval N : Notes attached to conditions
Reason: To comply with article 14 of the Town and Country Planning (Development Procedure) (No2) Order 2013 and to avoid the accumulation of unimplemented planning approvals.
Reason: The access, given its limited visibility and location on a primary highway, is acceptable only because of the very limited and small-scale nature of the use predicted for it.
Prior to the laying of the hardstanding for the proposed turning area, a sample of the material proposed for that turning area shall be submitted to and approved in writing by the Department.
Reason: In the interest of safeguarding the appearance of the application site.
Reason: In the interest of safeguarding neighbouring residential amenity and to ensure the provision of an appropriate landscape setting to the development.
