Settlers Hollow, King Edward Road, Onchan, Isle Of Man, IM3 2jp
The application site is the curtilage of an existing detached dwelling in Groudle Glen, Onchan, located within land designated as open space and of ecological interest under the Onchan Local Plan 2000. The proposal was to demolish and replace the existing dwelling with a new one, and the key planning issue referred to committee was the proposed increase in size relative to the original. The site sits in countryside designated as high landscape value, where new dwellings are generally not permitted under policy O/RES/P/22. However, the principle of a replacement dwelling had already been established by an earlier approval in principle (08/01349/A, granted November 2008). The officer's assessment focused on Housing Policy 14, which allows larger replacement dwellings in certain circumstances. The existing dwelling was described as of comparatively poor form and non-traditional in character — a modern split-level structure — which supported the case for a more substantial replacement.
The committee approved the application because the principle of replacing the dwelling had already been established by a prior approval, and the existing dwelling's poor, non-traditional form justified a larger replacement under the relevant exception in Housing Policy 14. The ecological and landscape designations were not considered to be materially worsened by the proposed development given the site's existing residential use.
Outside those areas designated for residential development new dwellings will generally not be permitted within the local plan area
In order to preserve the areas of interest for nature conservation within the study area, there will be a general presumption against any development which would have an adverse impact
General Policy 3
replacement of existing rural dwellings
General Policy 3: Development will not be permitted outside of those areas which are zoned for development on the appropriate Area Plan with the exception of: (a) essential housing for agricultural workers who have to live close to their place of work; (Housing Policies 7, 8, 9 and 10); (b) conversion of redundant rural buildings which are of architectural, historic, or social value and interest; (Housing Policy 11); (c) previously developed land (1) which contains a significant amount of building; where the continued use is redundant; where redevelopment would reduce the impact of the current situation on the landscape or the wider environment; and where the development proposed would result in improvements to the landscape or wider environment; (d) the replacement of existing rural dwellings; (Housing Policies 12, 13 and 14); (e) location-dependent development in connection with the working of minerals or the provision of necessary services; (f) building and engineering operations which are essential for the conduct of agriculture or forestry; (g) development recognised to be of overriding national need in land use planning terms and for which there is no reasonable and acceptable alternative; and (h) buildings or works required for interpretation of the countryside, its wildlife or heritage. 6.4 Planning Agreements 6.4.1 Where development is acceptable and in accordance with the provisions of this Plan and the relevant Area Plan, but raises issues which cannot be addressed by the imposition of planning conditions, the Department will seek to conclude an Agreement with the developer under Section 13 of the 1999 Town and Country Planning Act.
Housing Policy 4
Housing Policy 4: New housing will be located primarily within our existing towns and villages, or, where appropriate, in sustainable urban extensions (1) of these towns and villages where identified in adopted Area Plans: otherwise new housing will be permitted in the countryside only in the following exceptional circumstances: (a) essential housing for agricultural workers in accordance with Housing Policies 7, 8, 9 and 10; (b) conversion of redundant rural buildings in accordance with Housing Policy 11; and (c) the replacement of existing rural dwellings and abandoned dwellings in accordance with Housing Policies 12, 13 and 14. 8.5.6 The anticipated increase in the total number of dwellings on the Island over the Plan period is approximately 14%. By administering the programme of Area Plan preparation, the Department will ensure that there is sufficient land zoned for residential development to meet the overall housing requirement figure required by Housing Policy 1. The Department has resolved to prepare under the provisions of the Town and Country Planning Act 1999 four Area Plans which will concentrate upon larger areas of the Island. These will focus on the North, West, East and South of the Island and correspond with those areas discussed at paragraph 5.9 of the Spatial Strategy Chapter. 8.6 Affordable Housing 8.6.1 The Department is concerned about the increasing difficulties of securing the provision of affordable housing across the Island. The Department can, and does as a Housing Authority, intervene financially to provide financial support to local Authorities; financial support to prospective owner occupiers (through the House Purchase Assistance Scheme 2002) and by direct provision of new houses to rent. The provision of affordable housin g is a material consideration in the preparation of the development plan. In the current situation the Department considers that, to secure an adequate provision of affordable housing, it is appropriate to require that any area of land identified for hous ing purposes should include a contribution towards the provision of affordable housing. 8.6.2 There are currently around 1,584 (as at 31 st March 2007) households on the General Housing Waiting List. In addition, there are some 690 (as at 31 st March 2007) households registered with the Department under the House Purchase Assistance Scheme (HPAS). This indicates a total current need of some 2,274 households for affordable housing. (1) Sustainable Urban Extensions are defined in Appendix 1 8.6.3 In the current circumstances the Department considers that approximately 25 % of new housing provision should take the form of affordable housing. In assessing the appropriate percentage in each instance, the Department will have regard to the fact that the figure is a target over the Plan Period as a whole; to evidence of local housing need; to the nature of the land and viability of the scheme; and to the nature of existing adjacent housing. The 25% provision will be monitored and reviewed as part of any review of the Strategic Plan.
Housing Policy 12
Housing Policy 12: The replacement of an existing dwelling in the countryside will generally be permitted unless: (a) the existing building has lost its residential use by abandonment; or (b) the existing dwelling is of architectural or historic interest and is capable of renovation. In assessing whether a property has lost its habitable status (1) by abandonment, regard will be had to the following criteria: (i) the structural condition of the building; (ii) the period of non-residential use(2) or non-use in excess of ten years; (iii) evidence of intervening use; and (iv) evidence of intention, or otherwise, to abandon.
Housing Policy 14
Housing Policy 14: Where a replacement dwelling is permitted, it must not be substantially different to the existing in terms of siting and size, unless changes of siting or size would result in an overall environmental improvement; the new buildi ng should therefore generally be sited on the "footprint" of the existing, and should have a floor area (1), which is not more than 50% greater than that of the original building (floor areas should be measured externally and should not include attic space or outbuildings). Generally, the design of the new building should be in accordance with Policies 27 of the present Planning Circular 3/91, (which will be revised and issued as a Planning Policy Statement). Exceptionally, permission may be granted for bui ldings of innovative, modern design where this is of high quality and would not result in adverse visual impact; designs should incorporate the re -use of such stone and slate as are still in place on the site, and in general, new fabric should be finished to match the materials of the original building. Consideration may be given to proposals which result in a larger dwelling where this involves the replacement of an existing dwelling of poor form with one of more traditional character, or where, by its design or siting, there would be less visual impact. 8.11.3 It is unlikely that permission will be given for permanent replacement of dwellings which were never intended to have a permanent residential use, such as chalets and other structures built of materials for only temporary or seasonal use. 8.12 Extensions to Residential Property 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 gener al 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. (3) Floor Space is defined in Appendix 1 (1) Floor Area is defined in Appendix 1 8.12.2 Extensions to properties in the countryside As there is a general p olicy against development in the Island's countryside, it is important that where development exists, either in an historic or recently approved form, it should not, when altered or extended detract from the amenities of the countryside. Care therefore, must be taken to control the size and form of extensions to property in the countryside. In the case of traditional properties, the proportion and form of the building is sensitively balanced and extensions of inappropriate size or proportions will not be ac ceptable where these destroy the existing character of the property. In the case of non -traditional properties, where these are of poor or unsympathetic appearance, extensions which would increase the impact of the property will generally not be acceptable . It may be preferable to consider the redevelopment of non -traditional dwellings or properties of poor form with buildings of a more traditional style and in these cases, the Department may consider an increase in size of the replacement property over and above the size of the building to be replaced, where improvements to the appearance of the property would justify this.
