The Haven, Agneash, Isle Of Man, IM4 7ns
This application sought permission to erect an extension to the rear elevation of The Haven, a detached two-storey traditional cottage in Agneash, Laxey. Although the property has had previous extensions, the officer considered that several traditional characteristics of the building still applied. The application was refused on 10 February 2020. The decision-maker found that the proposed extension's design, finish, mass, and appearance would have an adverse impact on the existing property due to its inappropriate form. Because the extension could be seen from the roadside in two locations, it was also judged likely to harm the character and appearance of the surrounding area. The site sits within an Area of High Landscape Value that is not designated for development, which added weight to concerns about visual impact.
The application was refused because the proposed rear extension was considered to have an inappropriate design, finish, mass, and appearance that would harm the character of the existing property. The extension would also be visible from the roadside in two locations, causing a detrimental impact on the wider area. The proposal conflicted with housing policy on design and the Department's Residential Design Guide 2019.
Refusal Reasons
Housing Policy 16 of the Isle of Man Strategic Plan 2016
Housing Policy 16: The extension of non -traditional dwellings or those of poor or inappropriate form will not generally be permitted where this would increase the impact of the building as viewed by the public. 8.13 Conversion of Buildings to Flats 8.13.1 There are in the Island, and particularly in Douglas, many substantial buildings which, because of their size or form, are no longer suitable for the originally intended use as either single dwellings or holiday accommodation, but which are still structur ally sound. The Department has for many years encouraged the conversion of such buildings, where appropriate, into flats. 8.13.2 The size, layout, occupancy, etc., of flats are controlled by the Housing (Flats) Regulations 1982. However, all flats should also have a good external environment, characterised by - (a) a pleasant, clear outlook, particularly from the principal room(s) of the flat and (b) access to external space for the purpose of clothes-drying, refuse storage, car-parking, and general amenity. 8.13.3 Many buildings which are generally suitable for conversion into flats not only have very little space around them, but also have an annex or "outlet" at the rear. The Department may require the demolition, in total or in part, of such "outlets" even where the immediate use of the cleared space may not be possible, for example where more than one rear annex may be needed to be removed to gain access or highway work such as road widening may be required to make the cleared space useful. Such demolition will: (a) remove accommodation which has a poor environment and limited outlook; (b) permit the creation of parking space; and (c) assist in admitting light and air to the rear of the building proper. Where such demolition is not so required, the accommodation must generally be organised so that every flat has an outlook from the front of the building, and so that no flat is contained entirely within an "outlet". Exception may be made to this general approach where the environment at, and the outlook from, the rear are pleasant and open.

General Policy 3 of the Isle of Man Strategic Plan 2016
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.
Environmental Policy 1
Housing Policy 15 of the Isle of Man Strategic Plan 2016
Housing Policy 15: The extension or alteration of existing traditionally styled properties in the countryside will normally only be approved where these respect the proportion, form and appearance of the existing property. Only exceptionally will permission be granted for extensions which measure more than 50% of the existing building in terms of floor space (measured externally).
