Housing Policy 14

replacement dwellings in countryside

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.

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 ===== PAGE 3 ===== # 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.  ===== PAGE 4 ===== # 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. ===== PAGE 5 ===== # 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. ===== PAGE 6 ===== # 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 bloc

d/Governor 's Road junction. Any future applications will be considered on their merits taking into account the proposals set out in this plan and the Strategic Plan (see Maps 3 and 6). Natural Environment Proposal 2 (Green Gap) Between the settlements of Douglas and Onchan in the area straddling Blackberry Lane, development which would erode the separation and detract from the openness between the settlements will not normally be supported. Applications may be considered favourably if reason for an exception can be demonstrated in line with General Policy 3(g). Laxey and Baldrine - Encroaching ribbon development along the A2 C oast Road which connects Laxey and Baldrine has the potential to connect the two settlements. At present this area largely retains its sense of being in the open countryside with clear sea views. Additionally, services for networked water supply and other essential utilities would be difficult to provide for additional development in this area (see Maps 3, 7 and 9). Natural Environment Proposal 3 (Green Gap) Between the settlements of Laxey and Baldrine, development which would erode the separation and detract from the openness between the settlements will not be supported. Glen Vine and Crosby - These two settlements, although proximate in location, are separate and distinct in many ways. Consultation has clearly demonstrated this through the views expressed during the stages of plan development. In cases such as this, the breaks in the urban fabric and the features of nature which provide a sense of openness should be protected from development which would erode this (see Maps 3 and 10). Natural Environment Proposal 4 (Green Gap) Between the settlements of Glen Vine and Crosby, development which would erode the separation and detract from the openness between the settlements is unlikely to be supported. Douglas, Union Mills and Strang (see Maps 3, 4 and 8) Natural Environment Proposal 5 (Green Gap) Between the settlements of and Douglas, Union Mills and Strang, development which would erode the separation and detract from the openness between the settlements is unlikely to be supported. The Upland Environment The Manx Uplands are an iconic part of our landscape and heritage. Reference to the 'sweet mountain air' and 'green hills and rocks' are enshrined in our national anthem and the colours of the heather and gorse are woven into the very fabric of Manx tartan. The hills are a place of great beauty, yet for some they are also a place to work and for others a place to exercise or simply enjoy open space. Our Uplands are also home to plants and animals that whilst familiar to us, are rare and impor tant in a global and European context. Furthermore, the uplands are a rich repository of cultural and archaeological remains, which are sensitive to change and can easily be damaged by inappropriate development. Production of food is an important and obvi ous function of hill land. But surprisingly, the Manx hills provide everyday functions that most people take for granted. Peatlands, which cover most of our hills reduce the impacts of climate change by locking up carbon dioxide, collect and filter our drinking water and slow the passage of rainfall into streams and rivers, thus reducing downstream flood risk. These multiple uses are of great benefit to the economy of the Isle of Man and the well - being of its people. It is important that the hills continue to provide these benefits long into the future. Ensuring sustainable management of such a wide range of uses to the satisfaction of all interested parties whilst retaining functions essential to the well -being of the Isle of Man is of paramount importance. The Isle of Man Government is the owner and landlord for the majority of the Uplands in the East region and is therefore in a position to implement policy which will deliver the optimum range of ecosystem services. Appropriate and positive Upland management such as controlled rotational burning/cutting of heather and low intensity grazing helps to reduce the fuel load of the hill, provides firebreaks and reduces the risk of unplanned wildfires that further protects the biodiversity of the site, but also the vast amounts of carbon locked away in the peat soils. The majority of this work is carried out by The Department of Environment, Food & Agriculture's grazing and shooting tenants. The Manx Uplands are critically important from a habitat and biodiversity perspective. The hills in the East support a significant number of breeding hen harriers; however, other native Upland breeding birds such as curlew and red grouse have suffered severe declines in recent decades and as such are of high conservation concern. Strict control of access and recreational activity on vulnerable soils should be implemented to reduce soil erosion and subsequent carbon loss. Curlew and hen harriers are recognised as an internationally important species, while (within the EU) upland heather moorland is designated
