Erection of a replacement dwelling

Housing Policy 14

Housing Policy 14: Where a replacement dwelling is permitted, it must not be substantially different to the existing in terms of siting and size, unless changes of siting or size would result in an overall environmental improvement; the new buildi ng should therefore generally be sited on the "footprint" of the existing, and should have a floor area (1), which is not more than 50% greater than that of the original building (floor areas should be measured externally and should not include attic space or outbuildings). Generally, the design of the new building should be in accordance with Policies 27 of the present Planning Circular 3/91, (which will be revised and issued as a Planning Policy Statement). Exceptionally, permission may be granted for bui ldings of innovative, modern design where this is of high quality and would not result in adverse visual impact; designs should incorporate the re -use of such stone and slate as are still in place on the site, and in general, new fabric should be finished to match the materials of the original building. Consideration may be given to proposals which result in a larger dwelling where this involves the replacement of an existing dwelling of poor form with one of more traditional character, or where, by its design or siting, there would be less visual impact. 8.11.3 It is unlikely that permission will be given for permanent replacement of dwellings which were never intended to have a permanent residential use, such as chalets and other structures built of materials for only temporary or seasonal use. 8.12 Extensions to Residential Property 8.12.1 Extensions to Dwellings in built up areas or sites designated for residential use As a general policy, in built up areas not controlled by Conservation Area or Registered Building policies, there will be a gener al presumption in favour of extensions to existing property where such extensions would not have an adverse impact on either adjacent property or the surrounding area in general. (3) Floor Space is defined in Appendix 1 (1) Floor Area is defined in Appendix 1 8.12.2 Extensions to properties in the countryside As there is a general p olicy against development in the Island's countryside, it is important that where development exists, either in an historic or recently approved form, it should not, when altered or extended detract from the amenities of the countryside. Care therefore, must be taken to control the size and form of extensions to property in the countryside. In the case of traditional properties, the proportion and form of the building is sensitively balanced and extensions of inappropriate size or proportions will not be ac ceptable where these destroy the existing character of the property. In the case of non -traditional properties, where these are of poor or unsympathetic appearance, extensions which would increase the impact of the property will generally not be acceptable . It may be preferable to consider the redevelopment of non -traditional dwellings or properties of poor form with buildings of a more traditional style and in these cases, the Department may consider an increase in size of the replacement property over and above the size of the building to be replaced, where improvements to the appearance of the property would justify this.

Office of Architecture and Planning Government Offices, Douglas, Isle of Man. Rheynn Reiltys Ynnydagh as y Chymmyltacht.  £1.00 # GLOSSARY ## Catslide Roof A section of roof over a single storey extension, usually at a lower pitch than the main roof. ## Corbel A projecting block, usually of stone, supporting a beam or other horizontal member. ## Cornice Moulded ledge. ## Dormer A window placed vertically over a sloping roof with a roof of its own. ## Drip Moulding Projecting moulding above an opening to throw off water. ## Fanlight A window over a door. ## Fenestration The arrangement of windows on an external wall face. ## Gable Area of wall usually triangular at the end of a double pitched roof. ## Kneeler Horizontal projection at eaves level on a gable wall. ## Reveal The side of an opening in a wall between the front edge and the frame of a door or window. ## String Course Intermediate moulding projecting from the surface of a wall, usually corresponding to an internal floor level. ## Vernacular Building Buildings designed by those without formal training in design but using local materials and constructional methods formed over many years by local tradition. ## Weathering Inclined projecting surface to keep water away from walls and joints. 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 e
