What is an Area of Outstanding Natural Beauty? Areas of Outstanding Natural Beauty (AONBs) are nationally important landscapes. Within AONBs the main purpose of the Planning System is to ensure that any change through development conserves and enhances the natural beauty of the landscape. The law requires the production of an AONB Management Plan that sets out policies for the current management and future change of the area. Opportunities and challenges Chichester Harbour AONB is a low lying landscape dominated by tidal influences, with traditional harbour settlements. Marine activities form the major employment and leisure opportunities. Not only should new development lift the standard of the built environment but there are major opportunities for it to reflect the marine and leisure influences of the area, as well as improving the character and appearance of existing settlements. image used with kind permission of www.meynellhoolahanarchitects.com One of the future actions set out in the Management Plan was to develop user friendly guidance, based on the Landscape Character Assessment, to assist planning applicants in ensuring that any new development in the AONB is appropriate and of a high quality. How can this document help me? This design guidance describes design styles and materials for replacement dwellings or residential extensions throughout the AONB and for each Character Area. Check the map on page 11 for your Character Area and Local Planning Authority, so you know who you need to contact for further information. The final version of the Design Guidelines has been considered and endorsed by the Chichester Harbour Conservancy, Chichester District Council and Havant Borough Council as a material consideration in the assessment of development proposals within the Chichester Harbour Area of Outstanding Natural Beauty. The Guidelines should not be regarded as prescriptive but rather as a reference to establish basic design principles considered appropriate for use throughout the AONB and for each Character Area. Each planning application will still be assessed on its own merits and you are advised to seek further clarification about what might be appropriate for your site. www.conservancy.co.uk 1 2011 January image used with kind permission of www.meynellhoolahanarchitects.com Chichester Harbour Area of Outstanding Natural Beauty GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS Why is Chichester Harbour AONB special? Chichester Harbour Area of Outstanding Natural Beauty GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS What is a Landscape Character Assessment? Landscape character assessment is a systematic process, to understand, describe and classify the landscape. It is landscape character that makes each part of the landscape distinct, and affords each with its own particular identity. The approach is used as a basis for making judgements about the landscape, and for developing guidelines and strategies for its continuing enhancement. How is the AONB Landscape Character assessed? Chichester Harbour AONB Landscape Character Assessment (2005) and Havant Borough Townscape, Landscape and Seascape Assessment (2007) both identify the unique qualities of the AONB and how these might be conserved and enhanced. Character Areas were developed as part of the Assessments which give detailed character descriptions and identify positive and negative changes on the landscape. This divides the AONB into distinct landscape Character Areas, which have been used in the preparation of these design guidelines and are based on geographical places that people can recognise, such as Bosham or Emsworth. Do I need planning permission? To check whether planning permission is required you will need to contact either Havant Borough Council or Chichester District Council (Local Planning Authorities). They will check the history of your property and whether permitted development rights apply for any residential extension or maintenance to the property (such as replacement windows or works to surrounding trees and hedges). These permitted development rights are more restrictive in AONBs and Conservation Areas. If planning permission is required? If planning permission is required your Local Planning Authority will advise you on how to complete a planning application and what information you will need to provide in support. This may include a Design and Access Statement describing how your proposal fits into the character of the area. A Flood Risk Assessment can also be required in certain areas if your proposal is in the low lying area of the AONB. www.conservancy.co.uk 2 2011 January 3 General guidelines: AONB CHARACTER The flat coastal plain landscape of Chichester Harbour AONB, with its high intervisibility, is particularly vulnerable to visual intrusion from new development. This can adversely affect the natural beauty of the AONB, particularly where the development is visible in the wider landscape (from the harbour, public footpaths or open countryside). The landscape of Chichester Harbour AONB is unspoilt and agricultural, with woodlands and hedgerow trees particularly contributing to the wooded appearance of parts of the shoreline. In wider views the AONB landscape is framed by a backdrop of the Downs to the north. Gardens, boundaries and new planting Loss of garden space and boundary vegetation can lead to adverse impact on local character and existing hedges and trees should be preserved wherever possible. They may be important visual screens or the subject of Tree Preservation Orders. New landscape proposals cannot only help to reduce the impact of a new house, but planting of native species can form new wildlife habitats. 1. LANDSCAPE AND PLANTING In designing your new dwelling or extension you should consider both the house and its setting in the AONB landscape. You should consider how the scheme will contribute to the overall character of the area. When proposals are assessed the impact of the new building or extension will be assessed from public vantage points; these can be from roads, public footpaths or from the water. Landscape features can play an extremely important role in the design of a new house and can help to reduce the visual impact of a house in the wider landscape. However the proximity of trees and buildings can cause conflict in a number of ways. Root penetration can affect stability of foundations, and conversely foundation construction can affect the health and stability of existing trees if roots are damaged. You may be advised to seek the services of a specialist to help ensure that conflicts are kept to a minimum. Plant species House on left: increased visual impact with a stark outline against sky Your choice of plants should be appropriate to the setting of the house in the wider AONB landscape. Native species typical of Chichester Harbour AONB should be used; in any landscaping scheme or proposed boundary planting include: Trees or hedgerow trees: English Oak (Quercus robur), Field Maple (Acer campestre), Common Ash (Fraxinus excelsior), Holly (Ilex aquifolium; evergreen), Hawthorn (Crataegus monogyna; able to be coppiced to reduce height), Rowan (Sorbus aucuparia), Hazel (Corylus avellana; able to be coppiced to reduce height), Common Alder (Alnus glutinosa; able to be coppiced to reduce height) Less obtrusive: Foreground and background vegetation retained or planted; helps to soften the visual impact of new houses or extensions Hedgerow species: Hawthorn (Crataegus monogyna), Blackthorn (Prunus spinosa), Field Maple (Acer campestre), Hazel (Corylus avellana), Holly (Ilex aquifolium; evergreen), Dogwood (Cornus Sanguinea) Contemporary dwelling in Bosham: Roofline is set lower than vegetation backdrop, avoiding hard lines of the silhouette against the sky GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 4 General guidelines: 2. SCALE AND MASSING The scale, mass and design of your house or extension will be critical to ensuring that the development is appropriate to the character of the AONB landscape. Houses of a greater size or grander appearance may lead to a loss of local character. Where appropriate, your development proposals should complement surrounding development character. For example if your house plot is set within an area of predominantly single storey bungalows, then a two or three storey house or extension may not be acceptable. The position within the plot is very important to consider, not only for the siting of the house or extension itself, but also to make sure that the privacy and amenities, such as light, of neighbouring properties are preserved. 3. GUIDANCE ON SIZE INCREASE Extensions or replacement dwellings can have a significant impact on the wider AONB landscape, particularly when a significant increase in size is proposed. When considering substantial increases, a guideline of a 50% increase above the existing footprint, and a 25% increase above the existing ‘silhouette’ (on any elevation visible from the wider landscape) is likely to be the maximum increase that may be acceptable (provided the property has not already been significantly extended). For replacement dwellings, applicants should submit proposed elevations and plans with the outline of the existing house superimposed on the plans, so that the proposed size increase is obvious. The increase will be assessed on its impact as viewed from the wider landscape; this might be from the water, footpaths, or across open countryside. The acceptability of any increase in size (whether within the guideline limits or not) will be dependent on whether the site can accommodate the increase while still respecting local character by reflecting the surrounding pattern of development and spaces between buildings. Acceptability will also depend on the setting of the site within the landscape, and the design, materials and finishes employed. Larger replacement dwellings or extensions will require careful thought about siting, silhouette, height, massing and articulation, particularly of roof lines. A glossary of terms is included on page 32. FOOTPRINT Key Existing dwelling SILHOUETTE Proposed replacement dwelling Flood risk Predicted future rises in sea level mean that new properties may be required to be built on a higher level than existing ground; approximately 1 - 1.5m. Mitigation of the increased visual impact of this requirement is possible through careful design of roof lines, height of eaves and reduction of roof pitch. GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 5 General guidelines: 4. DESIGN OF EXTENSIONS In the design of an extension to an existing dwelling it is important to respect or complement the style of the main house. Repetition of vertical or horizontal elements can help to relate the extension to the main house. The scale and massing of an extension should generally be in scale and proportion to the main house, ie. roof pitches should reflect the existing. Side extensions should be carefully designed and usually work best when they are subservient to the main building. Extension subservient to main house with lower eaves and set back from front wall Sensitive joint scheme design in Itchenor for the extension of a pair of semi-detached houses: before above, after below Rear and side extensions should be carefully designed to avoid impact on neighbouring properties; you should also ensure that there is sufficient amenity or garden space left for the house. Loss of car parking spaces may also be unacceptable. If you are considering a front extension, be careful to ensure that this does not impact on the character of the local area as well as on neighbouring buildings. It might be possible to consider a joint scheme with your neighbours, for instance a larger porch if the front doors are adjacent. Ancillary buildings Careful thought should be given to the siting of these so as to avoid impact on neighbouring properties and dominance over the dwelling. The setting should not be intrusive in the landscape or in public views from the land or water. Garages, car ports and boat houses should be set back from the front face of the building to avoid dominating the street scene, and increasing the mass of a house. There should also be at least 6m of space so that a car can pull off the street. Sympathetic conservatory-style extension in keeping with the character of the house GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 6 General guidelines: 5. COLOUR, APPEARANCE AND FINISH Choice of colour and finish of materials can be one of the most important design factors in reducing the impact of the building on the landscape. Generally very light colours (such as white, cream and light grey) and large areas of intense strong colours do not blend well with the rural landscape of the AONB, which in general is characterised by subtler, darker colours. Above: Example of a house with areas of light colouring in a treed setting, showing how it stands out visually against the natural background. Below: Contemporary dwelling in Bosham (left of image): Darker colours for roof and facades reduce visual impact of the building in the wider landscape Large expanses of one colour can be undesirable as this may serve to increase the apparent size of the building. The use of predominantly darker tones and matt finishes can ensure that the building 'blends into' its setting. This can be particularly important in minimising impact, for example, where a replacement dwelling would result in a significantly larger building than its predecessor. Dark roofs can also help to reduce the visual perception of size of a building and are less conspicuous from the wider landscape. image used with kind permission of architect: www.sens.co.uk Emsworth: Before and after images show how careful choice of materials for remodelling of dwelling can dramatically reduce visual impact GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 7 General guidelines: image used with kind permission of www.meynellhoolahanarchitects.com However, the use of lighter colours and render can be appropriate in some areas, where they reflect the general character of the surroundings, for example in the historic core of a village. South Street, Emsworth: Light coloured finishes are characteristic of this row of houses in the historic core. Contemporary dwelling in Birdham: Darker materials fit well into a planted context Choice of colours and materials The use of materials that complement the character of the surrounding area is particularly important in maintaining and enhancing the character of the AONB. The use of traditional, natural (preferably locally sourced) materials is generally more appropriate than man-made synthetic / pre-coloured materials, as these lack the variation in colour and texture found in natural materials. Painted or pre-coloured cladding such as the increasingly popular grey/ blue ‘New England’ style cladding is unlikely to be appropriate in relation to the more traditional local styles and materials found within the AONB, and can be highly visually intrusive and ‘alien’ in a natural landscape setting. A small range of complementary materials can be used, however too much variation can create disharmony. In general terms, to ensure that a replacement dwelling or extension is in keeping with the setting or original house, materials should be chosen that respond to the landscape setting and/ or match or complement the existing house. Materials should be chosen which will weather well over time. Examples of particularly appropriate materials are shown on pages 9 and 10, with darker and more muted colour schemes also indicated. However the suitability of these examples will depend on the location and setting of the site, and other features of any particular proposal. GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 General guidelines: 6. WINDOWS AND GLAZING Understandably most proposals for new dwellings and extensions include large amounts of glazing to maximise light and, particularly in waterside locations, views across the harbour. However the visual impact of glazing, in particular the issue of reflection, is a key concern in the AONB. The Conservancy's education centre at Dell Quay clearly illustrates the reduction in visual impact achieved through the use of non-contrasting window frames. before 8 after Techniques Reducing impact of windows The design of windows is an important part in the development of a new or extended dwelling and should be of complementary scale, style, materials and proportion to the original dwelling and / or the character of the setting. From the outside of most buildings glass often appears highly reflective, increasingly so when seen from an oblique angle. Almost every type of architectural glass under the right conditions reflects the sky, clouds, or nearby trees and surrounding landscape. Night time lighting can also be a visual intrusion. Coated surface glass such as low emissivity and solar control glass can be seasonally useful in keeping heat in and sun radiation out, but these can be highly reflective and are unlikely to be appropriate in the wider landscape. Disproportionately large expanses of glazing or picture windows can have a very unsympathetic appearance and will tend to draw the eye from the wider landscape. Likewise, light coloured window frames can accentuate the prominence of windows, thereby increasing the intrusiveness of a building in the wider landscape. Simple design techniques can be employed to reduce the impact of glazing, particularly from reflection, which will also maintain a good balance of natural light: these can include the use of brise soleil, louvres, overhanging eaves and canopies. These can also help to reduce the problems of solar gain by creating shade, which may be particularly appropriate in south facing locations where light levels may be higher. Brise Soleil Image of Brise Soleil Louvres Windows can be fitted with fixed or movable slats that will admit light, allow views, but will reduced the visual impact of areas of glazing. Overhanging eaves Overhanging eaves can reduce the visual impact of large areas of glazing by blocking the direct path of sunlight, without affecting the views available from inside the building. Window frames Generally dwellings should be designed with proportionate windows; there should be more building than window. The visual impact of larger windows can be reduced by the use of vertical subdivision of frames, which helps to reduce the window proportions. This dwelling has been designed with upper and lower windows of same size, however the impact of the lower windows is reduced with the addition of vertical subdividing frames. White is often the traditional colour for window frames, and is frequently found on older buildings such as those within the historic core of the villages in the AONB. White or other light colours can also be appropriate in other parts of the built-up areas. However, careful consideration should be given to the colour of window frames where the building lies within a rural or natural setting and is visible in the wider landscape, i.e. from the land or the water. In these instances it is usually more appropriate to choose a more muted, darker or non-contrasting colour to the elevations, so as to minimise the visual intrusion of the building within its natural landscape setting. This is particularly relevant where a replacement dwelling or extension results in a significantly larger building than its predecessor. Examples are shown on pages 9 & 10. Horizontal structure projecting outwards above an area of glazing, with slanted struts that deflect direct sunlight, without affecting the views available from inside a building. Roof lights Internal natural light can be maximised by the inclusion of small conservation style rooflights. This is a particularly useful technique to introduce light on exposed roof slopes. Dormers Dormer windows should be in keeping and proportionate to the design and materials of the building; they should not dominate the facade. Choice of colours is also important. Soffits, fascias and guttering Where light coloured window frames are not appropriate, the colour of soffits, fascias and guttering should similarly be a subdued, dark or non contrasting colour to the elevations, or should match the colour of the window frames, as this also avoids increasing the prominence of the building in the AONB landscape. GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 9 General guidelines: EXAMPLES OF MATERIALS AND FINISHES Particularly appropriate materials may include: timber, tiles, slate, shingles, brick, flint and appropriately coloured render.

As well as the general guidelines for development in the AONB, each Character Area has a set of specific design guidelines. Your proposals may be for a property outside the boundary of the AONB, but might still be considered by Havant Borough Council and Chichester District Council to be development which would impact on the natural beauty of the AONB. There are a number of areas that can be easily identified as falling into this category. These are marked on the map with a star and they are: Areas within Havant Borough: Hayling Island: Treloar Road, Bracklesham Road and Eaststoke Avenue, Marine Walk, Salterns Lane, Laburnum Grove, Woodgaston Lane, and St Peters Road 11 Emsworth: Western Parade and part of Bath Road If this is the case, your proposals will be considered against their likely effect on the quality of the landscape. Outside of the built up area development will be resisted unless there is a compelling reason for its location and no alternative sites are available. Further information on these policies can be found in: Havant Borough Council Local Plan: Landscape Policy L1 Chichester District Council Local Plan: Rural Environment Policy RE4, Coastal Environment Policy C1 and Housing Policy H12.

Larger detached manor houses set within walled grounds Avoid further loss of trees and hedges Farm style complexes and barn conversions Any new development should be within the clusters based on ‘original hamlets’ rather than in outlying positions Distinctive landscape language Retain and create strong boundaries to properties: flint walls, hedges and fencing Use of traditional materials and building styles should be encouraged to reflect rural character References www.conservancy.co.uk January 2011 This area is covered by the Chichester Harbour AONB Landscape Character assessment Area G3 22 Materials Specific character design guidelines Brick Flintwork with brick detail Boundary walling Light coloured render Thatch Timber boarding ANCILLARY BUILDINGS Sensitively designed outbuilding complements design of main dwelling and reflects local character and materials. VARIATIONS IN MATERIALS Illustration of how traditional materials can be used on same style house in different ways in order to create variation without moving away from local distinctiveness REFLECTING RURAL CHARACTER Architectural design respects rural quality of Chidham Peninsula LOCALLY DISTINCTIVE MATERIALS New development shows how materials reflecting local character can be combined in order to create modern buildings of traditional rural appearance. Darker colours reduce visual impact of the building in the wider views across the peninsula. Hierarchy of roofs helps to soften impact by breaking up mass Mix of traditional materials helps to soften impact Trees and taller planted backdrop prevents stark silhouette Each planning application will still be assessed on its own merits and you are advised to seek further clarification about what might be appropriate for your site. GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 Harbour Peninsula: Chidham 23 Harbour peninsula: Bosham Harbour Peninsula: Bosham Location Area Character The area is predominantly wide flat arable fields with a complex and irregular pattern. There is a concentration of woodland to south around Bosham Hoe. Remnants of parkscapes and historic farmhouses are scattered across the area. GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS Chichester Harbour Area of Outstanding Natural Beauty Larger twentieth century shoreside houses, set in large garden plots, can have a more suburban character. Bosham is a picturesque village with a historic core, clustered around landmark church. Distinctive architectural language Key Issues Predominant materials in the historic core include: render, brick and flint, tile and thatch. There is a great demand for the redevelopment of detached houses. Many extensions to existing properties, with large areas of reflective glazing, are very unsympathetic to surroundings. Properties in central historic core are mostly terraced or closely built. Sympathetic management of shoreside gardens is required to ensure a natural edge. Avoid loss of waterside trees and hedges. Larger detached properties have important landscape settings that soften visual impact. Development should respond to existing settlement patterns, locally distinctive building styles, materials and landscape setting. Replacement features should reflect adjacent properties where appropriate and be sympathetic to the character of area; where possible renewing period features. Distinctive landscape language Views of landmark buildings across agricultural areas on edges of settlements are important to retain. The landscape setting of larger houses is very important to consider. Rooms in roofs; skylights and dormer windows should be carefully considered to minimise visual impact.

GUIDELINES FOR NEW DWELLINGS AND EXTENSIONS www.conservancy.co.uk Chichester Harbour Area of Outstanding Natural Beauty January 2011 Manhood Peninsula: West Wittering 31 Glossary Ancillary Layout Subsidiary or subservient, to the purposes of the main building. For example a building used for a variety of purposes, providing support to the use of the main building such as garages and outbuildings in relation to a house. The way buildings, routes and open spaces are placed in relation to each other. 32 Local distinctiveness The positive features of a place and its communities which contribute to its special character and sense of place. Articulation (architecture) Breaking down of a building's design into elements and the method of modelling these elements in terms of the shape or manner in which the elements come together and are connected. The articulation of a building reveals how the parts fit into the whole by emphasizing each part separately. Building elements Doors, windows, cornices and other features which contribute to the overall design of a building. Mass / Massing The combined effect of the arrangement, volume and shape of a building or group of buildings. This is also called bulk. Defined by a combination of height, bulk and silhouette of a building or group of buildings. Scale A projecting or suspended hood over a door or window. The size of a building in relation to its surroundings, or the size of parts of a building or its details, particularly in relation to the size of a person. Sometimes it is the total dimensions of a building, which give it its sense of scale: at other times it is the size of the elements and the way they are combined. The concept is a difficult and ambiguous one: often the word is used simply as a synonym for 'size'. Complementary Setting Building footprint The area of ground covered by a building. Canopy Complements or enhances the original without necessarily copying it. Conservation style rooflight Low profile skylight with slim sections and fitting flush fitting with the roof coverings. They have an authentically traditional appearance and often comply with planning requirements for listed buildings and conservation areas. The surroundings in which a building or landscape or other feature is experienced. Its extent is not fixed and may change as the building or feature and its surroundings evolve. Elements of a setting may contribute or detract from the appearance of the building or feature and may affect the way a building or feature is appreciated. Silhouette The overall shape of a building from a viewpoint in relation to its landscape setting, backdrop, other landmarks, adjacent buildings or groups of buildings. Dormer Any window projecting from the pitch of a roof. Soffit Eaves The underside or lining beneath a beam, or lintel, or of any projection from the face of a building. The lower edge of a sloping roof, where it overhangs the wallhead. Subservient / subordinate Fascia Feature brickwork Visually preserving the form and outline of the existing building by setting any extensions back from the main front wall of the existing building and keeping the height of the roof ridge and eaves below those of the existing building. Brickwork that emphasises the corners of walls or door and window openings often in a different colour from the main walls. Topography Gable A description or representation of artificial or natural features on or of the ground. The vertical part of the end wall of a building contained within the roof slope, usually triangular. Vernacular A board carrying the rainwater gutter. Hipped roof A hipped roof has no gables, it consists of four sloping sides where the ends of the roof are sloped rather than vertical. The way in which ordinary buildings were built in a particular place before local styles, techniques and materials were superseded by imports. View What is visible from a particular point. Landscape The appearance of land, including its shape, form, colours and elements, the way these (including those of streets) components combine in a way that is distinctive to particular localities, the way they are perceived, and an area's cultural and historical associations.
