Glen Cam Farm, Corlea Road, Ballasalla, Isle Of Man, IM9 3ba
This application sought permission to alter two windows and create a new entrance porch at Glen Cam Farm, Ballasalla, on the Isle of Man. The officer's report noted that the dwelling has a traditional cottage at its core but has been significantly altered and extended over time, incorporating modern elements. The property is visible above the boundary hedge from Corlea Road but is not considered prominent. The key planning questions were whether the works would increase the visual impact of the property and whether they would be sympathetic to its character and appearance. The application was permitted on 20 May 2021 through delegated decision.
The application was permitted on 20 May 2021 under delegated authority. The officer considered whether the works would increase the property's visual impact on the public and whether they would be sympathetic to the character of the dwelling. The property is already a mix of traditional and modern elements, and the proposed alterations were considered to fit within that context.
General Policy 2
The works are considered to accord with General Policy 2
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
Housing Policy 16
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.
Planning Circular 1/98
Planning Circular 1/98 # THE ALTERATION AND REPLACEMENT OF WINDOWS The Department of Infrastructure Planning And Building Control Division Murray House Mount Havelock Douglas Isle of Man IM1 2SF July 1998 # THE ALTERATION AND REPLACEMENT OF WINDOWS ## INTRODUCTION 1. This Planning Circular sets down the Department's policies in respect of the alteration or replacement of windows. These policies vary according to the age, merit and location of the building. For ease of use, the Circular divides buildings into several categories, and sets out the policies and reasoning for each category. ## NEED FOR PLANNING APPROVAL 2. This Circular should be read in conjunction with the recent Permitted Development Order (S.D. 664/97). The effect of the Order is that, with certain exceptions, the installation of a window in an existing aperture in a building erected after 1920 does not require planning approval. The exceptions are - a) Where the building is a registered building or in a conservation area, or in an area in respect of which the Planning Committee has passed a resolution to the effect that planning approval is required for such work; or b) Where the work would be in breach of a condition imposed on the grant of planning approval. ## GENERAL REASONING 3. The appearance of any building is strongly influenced by the detailing of its windows. The character and integrity of a building are usually best preserved by the retention and repair of the original windows, or, if this is not possible, the installation of replacements which respond suitably to the original design. In this context, "original" means those windows which were installed in the building at the time of its construction. If you are in doubt as to whether the existing windows are the originals, the staff in the Office of Planning may be able to give advice. ## BUILDING CATEGORIES 4. For the purposes of this Circular, buildings have been divided into the following categories:- a) Registered Buildings b) Buildings in Conservation Areas c) Buildings erected before 1921 and not falling within a) or b) which have largely retained their original character d) Other buildings erected before 1921 e) Buildings constructed after 1920 which do not fall into category a) or b) and which are not subject to previous planning conditions restricting the installation of replacement windows. Subsequent paragraphs of this Circular deal with each category in turn. ## Category a) REGISTERED BUILDINGS 5. Policy If the original windows are still in place they should preferably be repaired. If repair is impracticable, replacement windows MUST BE THE SAME as the originals in all respects, including the method of opening, materials and detailed design. This policy will be strictly applied other than where the particular circumstances are so exceptional as to justify a relaxation. Reasons for Policy: Registered Buildings are those buildings which are judged to be of special architectural or historic interest and which are already entered into the Protected Buildings register. Because of their special status, these buildings merit particular care and any work carried out by way of repair or alteration requires Registered Building Consent. Planning Approval and Registered Building Consent ARE ALWAYS required. Category b) BUILDINGS IN CONSERVATION AREAS 6. Policy If the original windows are in place they should preferably be repaired. If repair is impracticable, replacement windows which would be readily visible from a public thoroughfare MUST HAVE THE SAME method of opening as the originals. Whatever the material used in their construction, the windows MUST HAVE THE SAME pattern and section of glazing bars and the same frame sections as the original windows. Windows not readily visible from a public thoroughfare must have the same or similar pattern of glazing bars as the originals, but not necessarily the original method of opening, whatever the material used in the construction. Reasons for Policy: The Department has a duty to determine which parts of the Island are areas of special architectural or historic interest, the character of which it is desirable to preserve or enhance, and shall by order designate such areas as Conservation Areas. Planning Approval is required for all external works to properties in Conservation Areas to ensure that any proposals are in keeping with not only the individual building, but the special character and quality of the area as a whole. Planning Approval IS REQUIRED for alteration or replacement of window in the category of buildings. Category c) BUILDINGS ERECTED BEFORE 1921 AND NOT FALLING WITHIN CATEGORIES a) OR b) WHICH HAVE LARGELY RETAINED THEIR ORIGINAL CHARACTER 7. For ease of use, this category has been divided into two, based on the location of the building: i) Buildings in an Urban Setting

Foreword by the Minister for the Environment This circular, published in the form of a guide, sets down some basic principles which are intended to form a constructive approach to further protecting the quality of the countryside. Two of these objectives are the conservation of existing rural buildings and features and the sympathetic design of new development. Similar guides are proposed for areas having townscape quality. Taken together, these guides will provide a framework to assist in the preservation of the special character of the Island's environment and its buildings.  TONY BROWN # INTRODUCTION This Circular is intended to guide applicants, architects and builders on suitable ways to design and construct residential buildings in rural areas. It has been prompted by the need to conserve existing buildings of quality and to maintain the Island's individual identity. The landscape character of the countryside stemming from its geology, climate and agricultural use, is of high quality. It has been largely retained by strict planning restraint on development. Where new building is allowed under present controls, it is considered that this should respect the established rural character which has been the result of the vernacular and Victorian building of the past. Early farmhouses as well as being visually harmonious are still functional and their form is valid in terms of present constructional methods. They are simple, rational and visually faultless. Later Victorian buildings also contribute to the quality of the rural landscape. The essential building characteristics which act as patterns for proposed new residential buildings are described. These then form a basis by which to measure the acceptability of extensions to existing buildings or the design of any new permitted dwellings. The advice on housing design in the countryside is meant to apply primarily to the area outside settlements and urban areas covered by existing Written Statements and Planning Circulars. The area in question is indicated on the adjoining map. The definitive boundary should however be determined with reference to the approved Town Plans. The guide seeks to set a standard for the typical housing requirement in rural areas. It is intended that other guides to new building within a Victorian or Edwardian context will be prepared. An important related subject concerns agricultural buildings. This will need to be the subject of a separate Circular that deals with the retention and use of traditional farm buildings and the siting and design of new structures.  # PRESENT PLANNING POLICIES Current Circulars relating to residential buildings in the countryside emphasise both the need for the renovation of older houses and restrictions on development. New buildings are limited to essential agricultural activity which cannot be accommodated in existing buildings. These restrictions apply equally to extensions or minor works. Only certain items are excluded from the need for planning permission. These, together with work requiring permission, are summarised in Appendix 1. In general, present advice stresses the importance of relating new and existing buildings and of using traditional materials. These policies continue and are supplemented by more detailed design advice contained in this Circular. # POLICY 1 The removal or replacement of traditional elements including materials, windows or external works will generally not be acceptable. Work to buildings which date before 1920 should as far as practicable retain the original materials and form of the building. # THE VISUAL IMAGE OF THE MANX COUNTRYSIDE There is a visual image that symbolises for many the essential Manx countryside. This comprises lowlands of green undulating pastures contained by hedgerows and stone walls. This landscape is punctuated by simple rectangular crisp white farmhouses with slate roofs set amongst less prominent stone farm outbuildings and tree clumps. Above this comfortable habitat, the fields become steeper and change character, culminating in heather or rocky summits. The resulting prospect is a rich green land form scattered with small white houses on its lower slopes.  This image is the context which any new building must respect. The advice in this Circular is aimed to achieve this objective. # DESIGN PRINCIPLES FOR RURAL DWELLINGS ## SITING The siting of buildings may be in small groups or singly. Where single, they are often prominently placed in the landscape. New building groups should be located below the skyline. To achieve sympathy with the land form and for constructional economy, buildings generally should be placed along the contours rather than across them. An important factor in siting of buildings is the relationship with tree cover and hedgerows. The traditional farmstead has a natural and close functional relationship with field boundaries and often includes a tree group. This relationship should be maintained. New buildings should form a unity with any landscape features or existing buildings within the vicinity. Where no trees exist, new tree planting will be required to blend the building into the landscape.  Group of rural buildings sited below the skyline.  Single traditional rural building whose prominent location has been softened by tree and hedgerows.  Informal relationship between farm buildings together with tree planting achieves integration with the environment. ## POLICY 2 New buildings are to be integrated with the landscape and where in groups, with each other. Single buildings in prominent locations can only be considered if they are satisfactory in all respects and include landscape proposals. # PROPORTION AND FORM The proportion and form of country houses follow common patterns. The typical dwelling takes the form of a double cube volume topped by a steep pitch roof with gable ends. With these proportions and using the normal present day ceiling height of 2.5m, a two storey building gives an external plan dimension of 11.0m x 5.5m and will accommodate some 100 square metres of floor space. Variations on this floor area are achieved traditionally by lengthening or shortening the length of the block within the constraints of achieving a regular fenestration with a central entrance, or by rear extensions. The rear extensions are
