Corlea Farm, Corlea Road, Ballasalla, Isle Of Man, IM9 3ba
This application sought permission to replace part of the existing dwelling at Corlea Farm House, Ballasalla, convert an integral swimming pool annex to ancillary accommodation, erect a detached garage, and install 16 photovoltaic solar panels. The existing property is a traditional two-storey Manx stone farmhouse set approximately 80 metres back from Corlea Road, within a rural setting that also includes agricultural buildings and a horse stabling facility. The site is glimpsed from the road over hedgerows. The application was refused because the proposed replacement dwelling, by reason of its size and scale, was considered unsympathetic to the rural character of the area and constituted over-development. This was found to cause an adverse visual impact on the character of the setting.
The application was refused on 11 June 2025 by delegated decision. The proposed replacement dwelling was judged to be too large in size and scale for its rural setting, amounting to over-development with an adverse visual impact on the character of the surrounding area.
Refusal Reasons
Housing Policy 14
Replacement dwelling in the countryside
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.
Environment Policy 1
Protection of the countryside and its Ecology
Area Plan for the East sets out locally-applicable means for implementing the policies set out in the Isle of Man Strategic Plan 2016. In that Strategic Plan, we find the Environment Policies. Environment Policy 1 states: The countryside and its ecology will be protected for its own sake. For the purposes of this policy, the countryside comprises all land which is outside the settlements defined in Appendix 3 at A.3.6 or which is not designated for future development on an Area Plan. Development which would adversely affect the countryside will not be permitted unless there is an over- riding national need in land use planning terms which outweighs the requirement to protect these areas and for which there is no reasonable and acceptable alternative. Maintaining the purpose of this Area Plan as a means of implementation, there is some further direction to be found in the Strategic Plan, at paragraph 7.2.1: 'Whilst landscape and coastal change is inevitable, and in some cases desirable, the emphasis must be on the appropriateness of this change and the balance or equity between the needs of conservation and those of development. The primary goal must therefore be to respect, maintain and enhance the natural and cultural environment including nature conservation and landscape and coastal quality, and ensure its protection from inappropriate development.' Given the comprehensive nature of the Isle of Man Strategic Plan's Environmental Policies, only a small number of additional Proposals and Recommendations are necessary. In order to produce an implementable Area Plan for the East it is necessary to recognise those statutory desig nations and strategies which whilst having an Island-wide scope are highly relevant to the protection of environments within the Plan Area. An example is the UNESCO Biosphere status afforded to the Isle of Man. Island-level strategies identify crossborder issues and take account of the cumulative impacts of human engagement with nature. Area Plan Objectives i. To protect, conserve and enhance the natural and cultural environment of the plan area and promote biodiversity. ii. To improve the function, usability and provision of our green infrastructure and public spaces by providing a network of green spaces and features which are connected and where possible, accessible to the public. iii. To manage and improve flood risk and improve drainage conditions. iv. To support the working countryside and its custodians in maintaini ng a sustainable rural economy. Area Plan Desired Outcomes i. Where approved, d evelopment will be ecologically sustainable and designed to protect and where possible enhance biodiversity as well as mitigate and adapt to the effects of climate change. ii. The Green Infrastructure network will be established and fostered, connecting people with nature in a way that achieves the best shared outcomes for the urban and natural environment. iii. Statutory and non-statutory designations will continue to provide protection to the most important and most vulnerable cultural assets, habitats and environments in the plan area. iv. Beyond the towns and villages, the area as a whole will retain its landscape setting including its important visual interaction with the central uplands, central valley, coast and marine environment. Natural Environment Proposal 1 The Department supports the protection, creation and improvement of green infrastructure in the East, particularly in those locations which have the potential to be part of a Green Infrastructure Network. Applications for development must take into account any approved Government Green Infrastructure Strategies, but in any case, must identify how development proposals intend to contribute to the long term provision of a network of connected green spaces. UNESCO Biosphere In 2017, the Isle of Man became the first ever entire nation to achieve UNESCO Biosphere status. Project partners pledge to take steps to protect natural resources, develop the economy in a sustainable way and promote outstanding living landscapes. UNESCO Biosphere Reserves are established to connect people and the economy with nature, wildlife, culture, heritage and communities. Biosphere Reserves have three functions: Conservation: to contribute to the conservation of landscapes, ecosystems, species and genetic variation. Development: to foster economic and human development which is socio -culturally and ecologically sustainable. Logistic support: to support demonstration projects, environmental education and training, research and monitoring related to local, regional, national and global issues of conservation and sustainable development. The Isle of Man Biosphere is zoned into six areas . Examples of all of these can be found in the Eastern area: Terrestrial Core areas, Marine Core areas, Terrestrial Buffer zone, Marine Buffer zone, Terrestrial Transition areas and Marine Transition areas. There is some overlap with The Isle of Man's First Biodiversity Strategy 2015-20
General Policy 3
Exceptions to development in the countryside
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
Location of new housing and exceptions
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.
Spatial Policy 5
Building in defined settlements
Strategic Policy 5: New development, including individual buildings, should be designed so as to make a positive contribution to the environment of the Island. In appropriate cases the Department will require planning applications to be supported by a Design Statement which will be required to take account of the Strategic Aim and Policies. 4.4 Economy 4.4.1 The Spatial Strategy identifies the Major Employment Areas around the Island. While the majority of business and employment is focused around the Douglas Metropolitan Area, there are other major employment areas at Castletown, the Airport/Freeport, Peel, Ramsey and Jurby. The Department considers the distribution of employment areas provides a spread of employment opportunities around the Island. While recognising the opportunities for small scale local employment within existing centres it is considered new employment should, in the main, be concentrated within existing settlements or those major employment areas referred to in the Island Spatial Strategy and illustrated on the Key Diagram. Existing Local and new Area Plans will provide detailed boundar ies for these areas. From time to time Government may judge it appropriate to offer financial incentives to encourage economic activity or investment in particular parts of the Island.
General Policy 2
General Development Considerations
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: (a) is in accordance with the design brief in the Area Plan where there is such a brief; (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; (d) does not adversely affect the protected wildlife or locally important habitats on the site or adjacent land, including water courses; (e) does not affect adversely public views of the sea; (f) incorporates where possible existing topography and landscape features, particularly trees and sod banks; (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; (j) can be provided with all necessary services; (k) does not prejudice the use or development of adjoining land in accordance with the appropriate Area Plan; (l) is not on contaminated land or subject to unreasonable risk of erosion or flooding; (m) takes account of community and personal safety and security in the design of buildings and the spaces around them; and (n) is designed having due regard to best practice in reducing energy consumption. 6.3 Development outside of areas zoned for development
Transport Policy 4
Highway safety
Transport Policy 4: The new and existing highways which serve any n ew development must be designed so as to be capable of accommodating the vehicle and pedestrian journeys generated by that development in a safe and appropriate manner, and in accordance with the environmental objectives of this plan. 11.3.2 Notwithstanding policies within this plan which encourage travel by means other than private car it is anticipated that the number of vehicles using the Island's roads will continue to increase. This increase in demand is likely to lead to a greater need for road impro vements in order that travel can take place in a safe, effective, and environmentally acceptable manner. The Department of Transport will continue to assess the need for such improvements to public highways and undertake works where appropriate, with much of the improvement within existing roads carried out under the provisions of the Town and Country Planning (Permitted Development) Order2005. The need for improvements to the Island's highway network must be balanced against the environmental objectives of this plan.
