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 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.

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.

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.

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 block within the constraints of achieving a regular fenestration with a central entrance, or by rear extensions. The rear extensions are
