4. Design and Placemaking

4.1 This chapter is framed around the following objective:

Objective 1: To ensure that any new development is well-designed and of a high quality, adheres to the highest principles of sustainability and reflects the best qualities of the local character.

Design Principles

4.2 Good design has a major role in contributing to quality of life and creating attractive, liveable places. It is important that good design is inclusive and caters for all in society, irrespective of age or ability. The following links provide detailed information in respect of Building Regulations and inclusive and accessible design standards: Building Regulations (Part M); and Design of an Accessible and Inclusive Environment.

4.3 The Neighbourhood Plan is accompanied by a Village Design Statement (VDS), Design Guidance and Code. These are presented in free-standing appendices to the Neighbourhood Plan and should be used to guide proposals for development (see Information Box 2).

4.4 The table in Appendix 1 presents links between the VDS, Design Code and Neighbourhood Plan policies, including how and where further advice can be found. Design and contextual issues arising from any impact of Stanley Spencer paintings should also be considered, having regard to Appendix 5 and policy C-C12.

4.5 The VDS (Appendix 2) clearly states that Cookham ‘must not be immune to change, but the best of what Cookham has to offer should be protected and where possible, enhanced’. The qualities and characteristics of the area are important design cues for future development. This does not preclude innovation in design nor more contemporary use of materials, though where this does occur, proposals should be informed by existing character and setting, and harmonise with the buildings and landscape.

INFORMATION BOX 2: Neighbourhood Plan Design Guidance

Cookham Village Design Statement (VDS) A Village Design Statement (VDS) was prepared by the Cookham Village Design Statement Working Group, sponsored by the Parish Council and Cookham Society, and adopted by RBWM as a Supplementary Planning Document (SPD) in 2013. Given the relatively limited scale of change that has taken place since adoption, the analysis & recommendations within the VDS remain relevant.

Cookham Design Guidance and Code Alongside this Neighbourhood Plan, Design Guidance and an associated Code have been prepared. These build upon the analysis & recommendations contained within the VDS and supplement it.

The guidance illustrates how the VDS recommendations can be interpreted to reflect the character & qualities of the area. The document covers the entire Plan area — including guidance & codes to inform new development as well as wider initiatives such as improvements to the public realm & open spaces.

Additional to the Cookham Village Design Statement and Cookham Design Guide (above), Appendix 5 of this Neighbourhood Plan details those areas or elements of Cookham depicted in the paintings of Stanley Spencer. In certain instances, the information contained in this Appendix may influence the suitability of proposed design contexts or details.

Furthermore,The RBWM Building Height and Tall Buildings SPD(December 2023) provides guidance on appropriate building heights in the Parish and how applications should be considered.

4.6 The Parish Council supports design review for major applications for development, as well as smaller schemes in sensitive or important locations, such as within conservation areas or adjacent to rivers. This might include residential, commercial & mixed-use development proposals, infrastructure, community facilities, public realm & open space proposals.

Policy C-DP1: High Quality Design

  1. New development in Cookham should contribute to the creation of high quality places through a design-led approach to development underpinned by good practice principles.
  2. Development proposals must have regard to local character and should demonstrate how they have responded to the guidance set out in the Cookham Design Guidance and Code (Appendix 1) and the Cookham VDS (Appendix 2):
    1. Proposals for development should reflect the design qualities and characteristics that define the three settlements, reflected in building scale, height, form, materials, layout and plot sizes (Design Codes CV.01, CR.01 and DC.01).
    2. The scale, form, height, density, massing, footprint and roof form of buildings should be harmonious with neighbouring buildings, streets and spaces (Design Code DC.01). Proposals for tall buildings will generally be considered inappropriate and should reflect the prevailing context & principles established in the RBWM Building Height and Tall Buildings SPD. Flat roofs should be avoided, in line with the VDS.
    3. Building lines in new development should complement the street scene (Design Code DC.02).
    4. Development should make a clear definition between public & private areas, creating well-defined streets and spaces fronted by active development edges where windows and doors overlook & open onto the street or space (Design Codes CR.03 and CR.04).
    5. The use of materials in new development should be informed by traditional materials & presence of architectural details found on buildings in the settlement within which it is located (Design Codes CV.02, CR.02 and CD.02).
    6. Development should respond positively to its historic character & setting (Design Codes HE.01 – HE.03).
    7. Extensions to existing buildings should be subordinate in scale & form to the existing building, respect the street-scene & minimise impacts on existing residential amenity (Design Code DC.03).
    8. Development should maintain & provide open space and green infrastructure, be sensitive to settlement edges and, where opportunities are afforded by site location, provide connections to existing green space networks (Design Codes OS.01 – OS.04).
  3. Innovative schemes that respond to & reinterpret local design cues whilst harmonising with the surrounding context are supported.
  4. Development in Cookham should, as far as possible, follow the principles of inclusive design.
  5. Affordable housing should be well integrated into the design of the proposal as a whole.

Policy C-DP2: Rural Settlement Character

  1. Proposals for development must respect the rural character of the Parish. Development should:
    1. Retain spacing, as appropriate to the character of the area, between buildings.
    2. Retain accessible green space along the riverside, with views of the river & countryside provided between buildings.
    3. Whilst respecting the requirement to clearly define the public & private realm, make allowance for some individuality & irregularity in layout and building alignment, reflecting the organic nature of growth in the area.
    4. Where directly related to the development, retain and, where necessary, reinstate green roadside verges.
    5. Where appropriate, retain and repair historic walls, making use of traditional materials.
    6. Include soft landscaping, trees & hedgerows at the property boundary where appropriate, generally avoiding use of tall boundary walls, solid board fencing & gates and should have regard to the VDS. Gates should allow views through to the property or landscape beyond. Where new planting takes place this should incorporate non-invasive tree & shrub species.
    7. Surfacing in front gardens requiring planning permission should be permeable to minimise run-off. The retention of lawns & vegetation will be supported.
    8. Carefully manage parking to avoid visual impacts on the street scene, being integrated within the plot & set back from the frontage, and/or as part of a landscape scheme.
    9. Seek to minimise light pollution from exterior lighting.
  2. Development on the edges of settlements should seek to avoid abrupt edges that lack vegetation or landscaping. In sensitive environmental locations, provision of comprehensive landscape buffering will be supported. Native trees & shrubs should be used to reinforce the rural character of the area.
  3. Telecommunications infrastructure should be sensitively sited to reduce visual impact.

Policy C-DP3: Gardens

  1. Within defined settlement areas (Cookham Village and Cookham Rise), proposals for new homes in the gardens of existing homes will not be supported unless the following design requirements can be met:
    1. The openness of the area it is located within and spaciousness between buildings fronting the street is retained.
    2. Adequate vehicular access can be provided to the highway.
    3. There is no significant loss of residential amenity or privacy through overlooking and reduction of back-to-back distances between properties.
    4. The design of the proposed new development is compatible with the character & design of the main dwelling and the predominant scale & rhythm of housing surrounding the plot.
    5. Sufficient external space is retained such that it appears in keeping with its surroundings and is of a size & form that is functional & useable for the continuing needs of the main dwelling.
    6. Existing mature trees are retained, and biodiversity protected & enhanced.
    7. Parking is to be provided on-plot and should be carefully screened from adjacent properties.

Heritage Assets

4.7 The Cookham Village and Cookham Dean Conservation Areas (see maps in Appendix 3) were both originally designated in 1969. The key features of the Conservation Areas are summarised in Information Box 3.

INFORMATION BOX 3: Summary of Qualities of the Conservation Areas

In the Cookham Village Conservation Area Appraisal it is noted that the character & appearance of the Village is heavily derived from use of a limited range of traditional materials, building styles & features. The variety of boundary walls are also recognised as an important feature, including the importance of using traditional lime mortar for repairs.

The Cookham Dean Conservation Area Statement highlights the ‘overtly rural appearance’ of the area, areas of woodland which form pleasant backdrops to the small communities, and the distinctiveness of the greens & commons which often form ‘the central focus for groups of residential properties’.

The network of country lanes, tracks & footpaths threading their way through the area are also considered to be characteristic of the Conservation Area.

4.8 In addition to Conservation Areas, the Parish benefits from a wealth of listed buildings (see Appendix 4) as well as buildings of local significance as identified in the VDS and which comprise non-designated heritage assets as presented in Information Box 4. The local significance of each is set out in the Cookham VDS (Appendix 2).

INFORMATION BOX 4: Non-Designated Heritage Assets in the Parish

  • The Lock Keeper’s Cottage.
  • Terraced housing, Broom Hill.
  • Cookham Nursery School.
  • Retail parade between the medical centre and Pinder Hall.
  • Cluster of properties to the west of the High Road / Lower Road junction.
  • Lower Road Cottages.
  • Hedsor View Cottages, Alandale Cottages and West View, Station Road.

4.9 The impact of proposed development on a heritage asset and its setting must be considered, with the setting of a heritage asset defined as the ‘surroundings in which a heritage asset is experienced’. This is not fixed and may change over time. Development within the setting of a heritage asset may, for example, reflect and enhance positive characteristics in the area, relating for example to the scale and massing of buildings, styles of design and materials used. Good practice guidance Published by Historic England(The Setting of Heritage Assets, 2015) presents a good starting point for any assessment of the impact of proposed development on a Heritage Asset. This is summarised, with supporting illustrations, in the Cookham Design Guidance and Codes (Appendix 1).

4.10 Furthermore, there are many sites of archaeological interest in the Parish. There is archaeological evidence of prehistoric human activity, focussed on the raised gravel areas close to the River Thames, and of continuing settlement up to the present day, with the East Berkshire Heritage Environment Record containing 264 entries for the Parish.

4.11 Archaeological excavations in the field adjoining Holy Trinity Church have uncovered the remains and artefacts of an eighth century monastery ruled by Queen Cynethryth, widow of King Offa of Mercia. Cynethryth is the only Anglo-Saxon queen known to have been depicted on a coin. The monastery is believed to be the final resting place of Cynethryth. The Church is a listed building (grade II*). The listing extends to include the curtilage of the building. Given the importance of the finds, the Parish considers the site to warrant greater status (see Projects in Appendix 8). Further information on the early Anglo-Saxon period and relevance to Cookham is presented in Appendix 6.

4.12 Information on sites of particular archaeological importance in the Parish, prepared by Marlow Archaeology (MAS), is presented in the supporting material to the Neighbourhood Plan (Appendix 6). These are extensive and potentially significant. The Parish Council supports the submission of initial archaeological desktop assessments for development proposals affecting these sites.

Policy C-DP4: Heritage

  1. The Neighbourhood Area has a rich built heritage. All designated and non-designated heritage assets in the Neighbourhood Area must be conserved in a manner appropriate to their significance. Proposals affecting heritage assets should include a Heritage Statement that describes the significance of the heritage asset(s) affected and should consult the Historic Environment Record.

Commercial and Industrial Sites

4.13 Within the Parish there are a number of examples of former agricultural buildings and estates that have been converted for employment use. These have led to the sustainable re-use of vacant buildings and provided opportunities for the establishment and development of small businesses which generate income and employment opportunities for local people.

4.14 To help maintain the local economy while protecting the character of the local area from inappropriate development, the Plan supports the sustainable growth and expansion of business and enterprise through the development and, where appropriate, conversion of existing buildings. Specifically, this is intended to:

  • Promote viable and sustainable local businesses within the Parish.
  • Promote the diversification of rural businesses.
  • Encourage new businesses to provide a wider range of local produce, services and leisure facilities, to provide local employment and, as appropriate, attract visitors to the Parish.

4.15 Proposals for development will be expected to support sustainable and active travel to the site, avoid unacceptable impacts on highway safety and severe impacts on the road network as per paragraphs 115 – 118 of the NPPF.

Policy C-DP5: Local Employment Opportunities

  1. Proposals for new employment opportunities, including for micro and start-up businesses, will be supported. Proposals should:
    1. Not result in harm to highway safety, as demonstrated through a sustainable travel statement that includes proposals for maximising active travel and sustainable transport modes.
    2. Respect the local living environment and the amenities of neighbouring uses.
    3. Respect local character, including longer views (see Cookham Design Guidance and Codes and Cookham VDS).

Agricultural and equestrian development

4.16 The rural nature of the Parish is reflected in the numerous farm and agricultural buildings found in the area, including temporary agricultural buildings, often in quite close proximity to the settlements.

4.17 Policy ED4 (Farm Diversification) of the Local Plan establishes criteria that need to be met by proposals for new development on agricultural land, but where that development is not necessarily for agricultural purposes. In Cookham, it is both the diversification and expansion of existing agricultural activities, and the impact of these on residential amenity, the natural environment and landscape setting, that needs considering.

4.18 The VDS recognises that many farm buildings and operations need to change and evolve to remain fit for modern purposes. However, it notes that the potential visual impacts of new farm buildings might be reduced through careful choice of materials and use of planting which reflect the countryside setting. Noise impacts from buildings sited in close proximity to settlements can also impact residential amenity.

4.19 Furthermore, the impact of additional farm buildings and installations in the countryside, including the repurposing of agricultural buildings for other uses, contributes to the sense that development is extending into the countryside. This can undermine the nature of ‘gaps’ between settlements, particularly between Cookham Rise and Maidenhead, where the already narrow gap between the two is at risk from coalescence. This is exacerbated where buildings are sited in highly prominent positions. In the interests of visual amenity, the Parish Council is keen to ensure that new buildings in the countryside are not located in prominent locations.

4.20 Opportunities that are taken within the agriculture sector which help minimise the carbon footprint of the Plan area are supported. The Committee on Climate Change has set out a number of recommendations in their January 2020 report, Land Use: Policies for a Net Zero UK, that will help move towards a net-zero carbon use of agricultural land. These include low-carbon farming practices, such as controlled-release fertilisers and opportunities for carbon sequestering.

Policy C-DP6a: Agricultural Developments

  1. Where planning permission or prior approval is required for agricultural development, proposals should:
    1. Site any temporary or permanent agricultural building or mobile shelter for the use of livestock, poultry or other agricultural activity resulting in noise and disturbance, noxious odours and/or pest nuisance away from existing dwellings.
    2. Unless there are overriding operational reasons not to do so, site new agricultural buildings adjacent to existing agricultural buildings, in the interests of the openness of the Green Belt.
    3. Assess the landscape and visual impacts of the development and make use of materials appropriate to the agricultural setting and consistent with existing structures.
    4. Minimise the harm arising from the spillage of artificial lighting.
    5. Maximise opportunities to reduce energy consumption and make use of carbon-free sources of energy.
  2. The removal of agricultural buildings that are no longer needed and the reinstatement of ground conditions will be supported.

4.21 The Local Plan, at Policy QP5, sets out the policy approach to proposals for new equestrian development across the Royal Borough. This notes that proposals should provide sufficient land for grazing and exercise.

4.22 In the interests of minimising overdevelopment and protecting the openness and purposes of the Green Belt, the Parish Council is supportive of the removal of stables that are no longer needed and the reinstatement of ground conditions.

4.23 In Cookham there has been piecemeal development of equine buildings and subsequent (risk of) conversion of these for different uses, undermining the role and function of the Green Belt and separate identity of settlements. It is important to avoid the negative impacts of uncoordinated development in rural areas, to protect the intrinsic quality of the countryside (whilst accommodating opportunities for diversification which help sustain the rural economy).

Policy C-DP6b: Equestrian Development

  1. Proposals for the change of use of commercial stables should demonstrate, further to twelve months of active marketing, that the use is no longer commercially viable. The removal of equine buildings that are no longer needed and the reinstatement of ground conditions will be supported.

Sustainable building design and construction

4.24 In June 2019, RBWM declared an environment and climate emergency. Subsequently, an Environment and Climate Strategy was developed and approved in December 2020. The strategy presents RBWM’s vision and actions to achieve net-zero carbon emissions by 2050.

4.25 Policy SP2 (Climate Change) of the Local Plan requires development to be designed to incorporate measures to adapt to and mitigate climate change. Policy QP3 (Character and design of new development) suggests that development proposals are expected to contribute towards achieving high quality sustainable design. It states that development must be climate change resilient and incorporate sustainable design and construction, minimising energy demand, water use and waste, and maximising energy efficiency.

4.26 In March 2021 RBWM adopted an Interim Position Statement on Sustainability and Energy Efficient Design. Subsequently, RBWM has consulted on a Sustainability SPD(October 2023).

4.27 To help achieve the Government’s net-zero carbon targets the Position Statement and SPD establish a set of requirements for the design and construction of new development that includes, but is not limited to:

  • Submission of a Sustainability and Energy Statement for applications for new residential dwellings and non-residential floorspace in excess of 100 sqm.
  • Subject to feasibility, qualifying developments (as above) are expected to maximise potential for onsite renewable energy generation, with 12% of the total energy demand of the development being met on-site.
  • Adopting a fabric-first approach to development and where passive design measures, such as orientation and building form, are maximised.
  • All developments (other than householder residential extensions and non-residential development with a floorspace below 100 sqm) should be net-zero carbon, unless this would not be feasible, and include an energy assessment showing how the net-zero target will be met.

4.28 The Government will introduce the ‘Future Homes Standards’ in 2025 which will require new homes to achieve a 75-80% reduction in carbon emissions above current standards. The Sustainability SPD establishes good practice benchmarks and, wherever possible, expects applicants for new development to demonstrate greater energy and carbon reductions.

4.29 The Sustainability SPD makes reference to Passivhaus standards (see Glossary) as a means to achieve energy and carbon savings. The Parish Council will support proposals for new buildings that are ‘Future Homes standard’ ready and, in particular, those which exceed these standards and achieve zero or near zero net energy consumption in line with the Passivhaus Classic Standard. Good practice guidance relating to the design of Passivhaus Classic Standards is presented in the Sustainability SPD. This includes:

  • Using simple and compact building forms, avoiding or limiting features such as stepped roofs, terraces, overhangs and balconies, all of which increase the surface area of the building and decrease the energy efficiency of the building.
  • Orientating buildings to optimise solar gain and prevent overshadowing. Elevations facing ±30° south will benefit from solar gains all year round. Vertical and horizontal shading, such as brise-soleil, should be used to help control solar shading and gains at different times of the year.
  • Minimising heat loss from north facing facades through the use of smaller windows, offset by larger windows on south facing facades to allow for solar heat gain. This should be reflected in the internal layout of the building and location of habitable rooms.
  • Designing airtight buildings and ventilation systems that maintain good air quality whilst reducing heat loss. Mechanical Ventilation and Heat Recovery units should be installed in new buildings. Dual aspect buildings are favoured, allowing for cross ventilation.
  • Install and use heat pumps as a low carbon way of heating the property. Solar Photovoltaic panels can also be utilised. Roof tiles and panels should be designed such that they are sensitive to the setting and views across the landscape.

4.30 Support is given to proposals that incorporate the above, subject to compliance with wider development plan policies.

4.31 The Sustainability SPD also makes clear that the embodied carbon of existing buildings also requires awareness and good design, with the refurbishment and retrofit of existing buildings preferred over demolition and redevelopment. Historic England has published guidance in respect of the retrofitting and refurbishment of historic buildings (Advice Note 14: Energy Efficiency and Traditional Homes).

Policy C-DP7: Sustainable Design and Construction

  1. Innovative approaches to the construction of low carbon homes, including construction to Passivhaus standards, and which demonstrate sustainable use of resources and high energy efficiency levels, will be supported. Subject to topography, layout and good design principles, buildings should be orientated to maximise solar gain and use design features that also provide for solar-shading, whilst also creating a consistent building frontage to the street. The creation of airtight buildings that benefit from dual aspects and include cross-ventilation, and which allow for efficient heating and cooling of buildings and the integration of efficient, renewable energy technologies within the development, including, as appropriate, district, ground and air source heat pumps, photovoltaics and solar panels, will be supported.
  2. Changes to buildings to incorporate energy efficiency measures and opportunities for ‘self-generation’ should respond positively to the scale, grain, massing and materials of adjacent buildings, and be sensitive to landscape and historic character.
