This application sought permission to erect a rear conservatory at Crofton, The Crofts, Castletown — a substantial two-storey limestone dwelling and Registered Building. The application was linked to a separate listed building consent application (17/01065/CON). The application was refused on 30 May 2018. The decision-maker found that the proposed materials, particularly the use of uPVC windows in place of the existing timber ones, were inappropriate for a pre-1920 Registered Building. While a conservatory addition was not ruled out in principle, the design and materials were judged to harm rather than protect or enhance the building's character. The applicant did not provide sufficient justification for using modern materials on a historic building, which was a further reason for refusal.
The application was refused because the proposed materials and general design were considered harmful to the character of a Registered Building. Specifically, replacing existing timber windows in the conservatory with uPVC was judged inappropriate for a pre-1920 limestone building. The applicant also failed to provide sufficient justification for using modern materials on a listed structure.
Refusal Reasons
Strategic Policy 4(a)
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 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.
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).
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.
