Registered Building Consent for alterations to existing dwelling - part retrospective - RB 62 (in associated with PA 18/01287/GB, and forming amendments to 17/00793CON)

Environment Policy 30

Environment Policy 30: There will be a general presumption against demolition of a Registered Building. In considering proposals for demolition or proposed works which would result in substantial demolition of a Registered Building, consideration will be given to:  the condition of the building;  the cost of repairing and maintaining it in relation to its importance and the value derived from its continued use (based on consistent long-term assumptions);  the adequacy of efforts made to retain the building in use; and  the merits of alternative proposals for the site.

Environment Policy 31

Environment Policy 31: There will be a presumption against the removal o f any Registered Building from the Register.

Environment Policy 32

Environment Policy 32: Extensions or alterations to a Registered Building which would affect detrimentally its character as a building of special architectural or historic interest will not be permitted. 7.27 Change of Use of Registered Buildings 7.27.1The best use for a Registered Building is usually the use for which the building was designed. However, it is recognised that it is often necessary to look for a new use to secure the economic future of the b uilding. It is important therefore that any new use is appropriate and that physical alterations are sensitive to its character. (1) Curtilage is defined in Appendix 1

Environment Policy 33

change of use of Registered Buildings

Environment Policy 33: The change of use of Registered Buildings will only be permitted if the proposed use is appropriate and any alterations associated with the change are not detrimental to its character as a building of special architectural or historic interest. 7.28 Traditional Building Materials 7.28.1 Traditional building materials can be classified as stone for walls , slates for roofs and softwood for window frames. Local materials help to form the character of settlements in the Island. For example, sandstone was a common building material in the development of much of the older parts of Peel and limestone was historically used in Castletown. Whilst the original sources of some materials are no longer operating, reclaimed material from old buildings is often available. Such re-use will be particularly encouraged where sites are to be redeveloped and there is evide nce of material on site which can be recycled and reused. It will, however, not be appropriate to demolish historic buildings merely to reclaim usable materials. Another important aspect when attempting to retain the historic building stock is the use of the most appropriate mortar; common across the Island's built environment has been the use of lime-based mortar and washes.

Environment Policy 34

Environment Policy 34: In the maintenance, alteration or extension of pre -1920 buildings, the use of traditional materials will be preferred. 7.29 Development within Conservation Areas 7.29.1 Conservation Areas are designated where the Department is satisfied that there is an area of special architectural or historic interest, the character of which it is desirable to preserve or enhance. Accordingly, the Department will; i. appraise and review existing Conservation Areas; and ii. designate new Conservation Areas where Conservation Area appraisals have revealed individual areas to be worthy of such status. 7.29.2 Development proposals within Conservation Areas will be expected either to preserve or enhance their character or appearanc e. Development proposals should be in accordance with the Department's conservation policies set out in Planning Policy Statement 1/01, "Policy and Guidance Notes for the Conservation of the Historic Environment of the Isle of Man." There is generally gra nt assistance available to help in the use of appropriate materials and positive and appropriate development within Conservation Areas.

Environment Policy 35

Environment Policy 35: Within Conservation Areas, the Department will permit only development which would preserve or enhance the character or appearance of the Area, and will ensure that the special features contributing to the character and quality are protected against inappropriate development. 7.30 Development adjacent to Conservation Areas 7.30.1 It is often the case that important views into and out of a Conservation Area can contribute significantly to its character. It is necessary to assess the impact any development adjacent to conservation areas may have on such views.

POLICY RB/3 General criteria applied in considering registered building applications

POLICY RB/3 General criteria applied in considering registered building applications The issues that are generally relevant to the consideration of all registered building applications are:- • The importance of the building, its intrinsic architectural and historic interest and rarity, relative to the Island as a whole and within the local context; • The particular physical features of the building (which may include its design, plan, materials or location) which justify its inclusion in the register; descriptions annexed to the entry in the register may draw attention to features of particular interest or value, but they are not exhaustive and other features of importance, (e.g. Interiors, murals, hidden fireplaces) may come to light after the building's entry in the register; • The building's setting and its contribution to the local scene, which may be very important, e.g. Where it forms an element in a group, park, garden or other townscape or landscape, or where it shares particular architectural forms or details with other buildings nearby (including other registered buildings).

POLICY RB/4 USE

POLICY RB/4 USE In considering a proposal for change of use of a registered building, the principal aim should be to identify the optimum viable use that is compatible with the fabric, interior and setting of the building, all of which affect its special character as a building of merit. An applicant will have to illustrate that the effect of any proposed changes upon the architectural and historic interest of the building will be minimised.

POLICY RB/5 ALTERATIONS AND EXTENSIONS

POLICY RB/5 ALTERATIONS AND EXTENSIONS In considering whether to grant planning approval for development which affects a registered building or its setting and in considering whether to grant registered building consent for any works, the Department shall have special regard to the desirability of preserving the building or its setting or any features of special architectural or historic interest which it possesses. Registered building consent is required for the building's alteration in any way which would affect its special architectural or historic character. There will be a general presumption against alteration or extension of registered buildings, except where a convincing case can be made, against the criteria set out in this section, for such proposals. Applicants for registered building consent for alteration or extension to a registered building must be able to justify their proposals. They will be required to show why the works which would affect the character of the registered building are desirable or necessary and they should provide full information to enable the Department to assess the likely impact of their proposals on the special architectural or historic interest of the building and on its setting. Where registered buildings are the subject of successive applications for alteration or extension, consideration will also be given to the cumulative affect upon the building's special interest as a result of several minor works which may individually seem of little consequence.

POLICY RB/6 DEMOLITION

presumption against demolition

POLICY RB/6 DEMOLITION There will be a general presumption against demolition and consent for the demolition of a registered building should not be expected simply because redevelopment is economically more attractive than repair and re-use of an historic building; or because the building was acquired at a price that reflected the potential for redevelopment, rather than the condition and constraints of the existing historic building. Where proposed works would result in the total or substantial demolition of a registered building, an applicant, in addition to the general criteria set out in RB/3 above, should be able to demonstrate that the following considerations have been addressed:- In judging the effect of any proposed alteration or extension to a Registered Building, it is essential to have assessed the elements that make up the special interest of the building in question. They may comprise not only obvious features such as a decorative facade, or an internal staircase or plaster ceiling, but may include the spaces and layout of the building and the archaeological or technological interest of the surviving structure and surfaces. These elements can be just as important in the simple vernacular and functional buildings, as in grander status buildings. Cumulative changes reflecting the history of use and ownership can themselves present an aspect of the special interest of some buildings, and the merit of some new alterations or additions, especially where they are generated within a secure and committed long-term ownership, are not discounted. The destruction of historic buildings is in fact very seldom necessary for reasons of good planning: more often it is the result of neglect, or failure to make imaginative efforts to find new uses or incorporate them into new developments. • The condition of the building, the cost of repairing and maintaining it in relation to its importance and to the value derived from its continued use. Any such assessment should be based on consistent and long term assumptions. Less favourable levels of rents and yields cannot automatically be assumed for historic buildings and returns may, in fact, be more favourable given the publicly acknowledged status of the building. Furthermore, historic buildings may offer proven performance, physical attractiveness and functional spaces, that in an age of rapid change, may outlast the short-lived and inflexible technical specifications that have sometimes shaped new developments. Any assessment should take into account possible tax allowances and exemptions. In rare cases where it is clear that a building has been deliberately neglected in the hope of obtaining consent for demolition, less weight should be given to the costs of repair; • The adequacy of efforts made to retain the building in use. An applicant must show that real efforts have been made, without success, to continue the present use, or to find new uses for the building. This may include the offer of the unrestricted freehold of the building on the open market at a realistic price reflecting the building's condition. • The merits of alternative proposals for the site. Subjective claims for the architectural merits of a replacement building should not justify the demolition of a registered building. There may be very exceptional cases where the proposed works would bring substantial benefits for the community; these would have to be weighed against preservation. Even here, it will often be feasible to incorporate registered buildings within new development, and this option should be carefully considered. The challenge presented by retaining registered buildings can be a stimulus to imaginative new designs to accommodate them. CONTROL OF UNAUTHORISED WORKS Section 15 of the Act provides that no works may be executed:- (a) for the demolition of a registered building, or (b) for its alteration or extension in any way which would affect its character as a building of special architectural or historic interest, unless they are authorised under the Act and the Department has granted written consent for the execution of the works ("registered building consent") N.B. It should be noted that Section 15 of the Act does not apply to works for demolition, alteration or extension of :- i) any building which is for the time be ing the subject of a preservation order under section 11 of the Manx Museum and National Trust Act 1959, or ii) a building for the time being included in the list of monuments prepared under section 13 of the said Act.
