Planning Policy Statement 1/01 - Conservation of the Historic Environment of the Isle of Man

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 Policy In the individual building, or group of buildings, whose principal elevations are readily visible from a public thoroughfare, if the original windows are in place, it may be possible to repair and renovate them. This can take place without permission, and will be encouraged by the Department. If repair is impracticable, or existing windows are not the originals, the preference will be for replacement windows in the said principal elevations to have the same method of opening as the originals. Whatever the materials used in their construction, the windows MUST HAVE the same or similar pattern and section of glazing bars and the same or similar frame sections as the original windows. Windows are not part of the principal elevations and which are not readily visible from a public thoroughfare should preferably 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 their construction. Reasons for Policy: In many of our towns there are individual and groups of buildings which, although not worthy of Registration and not located in Conservation Areas, make a most important contribution to the local townscape; e.g. prominent corner sites or terraces. Where these buildings remain substantially unaltered, the aim is to encourage their enhancement in response to the original architectural concept. Planning Approval IS REQUIRED for alterations or replacement windows in this category of buildings. ii) Buildings in a rural setting Policy In an individual building, or group of buildings, whose principal elevations are readily visible from a public thoroughfare, if the original windows are in place, it may be possible to repair and renovate them. This can take place without permission, and will be encouraged by the Department. If repair is impracticable or the existing windows are not the originals, the preference will be for replacement windows on the said principal elevations, to have the same method of opening as the originals. Whatever the material used in their construction, the windows MUST HAVE the same or similar pattern and section of glazing bars and the same or similar frame sections as the original windows. Windows not part of the principal elevations and which are not readily visible from a public thoroughfare should preferable have the same or similar pattern of glazing bars as the originals, but not necessarily the original method of opening, whatever the material use in their construction. Reasons for Policy: The Island is fortunate in that it still retains a considerable number of unspoilt traditional vernacular buildings which epitomise the quality of the rural landscape. These buildings may not be worthy of Registration, and may not be located in Conservation Areas, but they do make a most important contribution to the traditional character of the rural landscape. Where these buildings remain substantially unaltered, the aim is to encourage their enhancement whilst preserving the original vernacular style. Planning Approval IS REQUIRED for alteration or replacement of windows in this category of buildings. Category d) OTHER BUILDINGS ERECTED BEFORE 1921 8. Policy Replacement windows should preferably be the same or as similar to the originals in the pattern of the glazing bars. However, provided that the glazing pattern is retained, a more relaxed approach will be taken to the replacement of windows in such properties. Reasons for Policy: Many buildings fall within this category and although there is little in the way of restriction, the aim is to encourage simulation of the original glazing pattern and this will apply particularly to buildings which are part of a larger group, such as a terrace, where replacement windows, if carefully designed, may serve to enhance the overall appearance of the group. Planning Approval IS REQUIRED for alteration or replacement of windows in this category of buildings. Category e) BUILDINGS CONSTRUCTED AFTER 1920 WHICH DO NOT FALL INTO CATEGORIES a) OR b) AND WHICH ARE NOT SUBJECT TO PREVIOUS PLANNING CONDITIONS RESTRICTING THE INSTALLATION OF REPLACEMENT WINDOWS. 9. The installation of replacement windows in these buildings does not require planning approval. The Department nevertheless recommends that the design of such windows should respect the architectural style of the building. ## FINANCIAL ASSISTANCE 10. Attention is drawn to the fact that the repair of existing windows or the installation of replacement windows may qualify for grant assistance under Financial Assistance Schemes which the Department operates. Further information regarding the availability of Grant Assistance is obtainable from the Finance Section of the Department. ## REVOCATION AND STATUS 11. Planning Circular 2/93 (Replacing External Doors and Windows) is herby withdrawn. 12. This Circular is issued by the Department in accordance with Article 11 (2)(a)(vi) of the Isle of Man Planning Scheme (Development Plan) Order 1982. 13.

CA/6 Demolition in Conservation Areas

POLICY CA/6 DEMOLITION Any building which is located within a conservation area and which is not an exception as provided above, may not be demolished without the consent of the Department. In practice, a planning application for consent to demolish must be lodged with the Department. When considering an application for demolition of a building in a conservation area, the general presumption will be in favour of retaining buildings which make a positive contribution to the character or appearance of the conservation area. Similar criteria will be applied as those outlined in RB/6 above, when assessing the application to demolish the building, but in less clear cut cases, for example, where a building could be said to detract from the special character of the area, it will be essential for the Department to be able to consider the merits of any proposed new development when determining whether consent should be given for the demolition of an unregistered building in a conservation area. Account will be taken of the part played in the architectural or historic interest of the area by the building for which demolition is proposed, and in particular of the wider effects of demolition on the building's surroundings and on the conservation area as a whole. ADVERTISEMENT CONTROL All external advertisements affect not only the appearance of the building upon which they are displayed, but also the neighbourhood where the building is located. This will apply particularly to illuminated signage which is often formed from shiny, nontraditional materials and can result in an unsuitable and harsh appearance which detracts from the character of the building and a conservation area as a whole. The aesthetic quality of a building can be markedly affected by the installation of inappropriate external signage. Where matters such as Corporate Image are a consideration; for a conservation area the Department may require a deviation from what might be acceptable in other high street locations and many large corporate bodies do have alternative designs of signage which might be suitable for use in conservation areas. In many cases it will be necessary for signage to adopt traditional design and materials, in keeping with the character of the building and neighbourhood as a whole. Externally illuminated signage with the appropriate detailing and colour rendered lamps, may be judged suitable. ABSENCE OF PERMITTED DEVELOPMENT Permitted Development Orders which apply elsewhere and enable minor development to be carried out in particular circumstances, may apply in designated Conservation Areas, but to a more limited extent. Most proposed development and any proposed demolition will require to have first been granted planning approval before any works may be progressed. If in any doubt, property owners are advised to consult the Department direct, rather than to rely upon the advice of a third party. FINANCIAL ASSISTANCE Work which might be considered as preserving the architectural or historic interest of an individual building, or which might be judged as enhancing the special character of a Conservation Area, historic townscape or the Island's rural landscape, may qualify for financial assistance under one of the schemes which the Department operates. Each case will be judged upon its own particular merits. DEMOLITION Under Section 19 of the Act, conservation area designation introduces control over the demolition of most buildings within conservation areas. Those buildings which are exempted from such control are listed in the said Section 19, but may be summarised as follows:- (a) registered buildings; (b) a building for the time being the subj ect of a preservation order under section 11 of the Manx Museum and National Trust Act 1959, (c) a building for the time being included in the list of monuments prepared under section 13 of that Act; or (d) any buildings, a description of which is specified in a direction issued by the Department under Section 19 subsection (2) of the Town and Country Planning Act 1999, which are by virtue of such direction, are excluded for the time being from an order designating a conservation area. IMPACT ON THE HISTORIC ENVIRONMENT OF TRANSPORT AND TRAFFIC MANAGEMENT IMPACT OF PROPOSALS TO BE MINIMISED Major new transport infrastructure development can have an especially wide-ranging impact on the historic environment, not just visually and physically, but indirectly, for example by altering patterns of movement or commerce and generating new development pressures or opportunities in historic areas. There is already in place an informal framework which allows for early dialogue between the Department of Transport, the Local Authority and the Department and it is essential that such consultation should continue to take place where any changes in such infrastructure are propose
