// What is our vision? In 2020 West Gorton will be the City’s most dynamic, forward-looking, environmentally sustainable neighbourhood. It will promote healthier lifestyles and community well being in a zero carbon setting. With an international reputation for green solutions for modern living, West Gorton will be a highly attractive place to live, work and visit. It will be supported by zero carbon energy generation with new development achieving level 6 for sustainable homes. The existing housing stock will incorporate high quality, up to date energy efficient technologies and sustainable water and waste management solutions. Homes and community facilities will be set within a high quality public realm that supports a diverse ecology with appropriate tree, shrub and ground cover species planted to enhance sustainability . West Gorton’s green infrastructure will also incorporate design features that will manage flood risk through a network of rills, swales and rain-gardens. The public realm will further support opportunities for recreation, sport and leisure with cycle and pedestrian links creating opportunities to connect the neighbourhood to the range of quality facilities that east Manchester and the city centre have to offer; including the nearby Eastlands Sports complex, good schools, local retail, public parks. West Gorton will be an area of low car dependency, with greater use of public transport. The area will provide opportunities for residents to grow their own food, further promoting the health of the community and supporting local ecology.
// Taking the vision forward Experience of neighbourhood planning, new house building and complex regeneration processes across East Manchester over the last 10 years has led to the approach set out here. Current economic, and environmental conditions demand new, innovative approaches to development. The critical challenge being to continue to secure investment and bring about much needed improvements to the quality of life in West Gorton, whilst not compromising on our vision to create a new family focused neighbourhood based on high quality design and environmental quality. The coordination and phasing, of new development and refurbishment works, alongside good quality neighbourhood management will be complex and demanding. Meeting the needs of residents whose daily lives will be disrupted will be of paramount importance to all involved.
To take forward Manchester’s sustainability aspirations, this integrated design code and environmental plan for West Gorton outlines a zero carbon, energy efficient, green vision for the neighbourhood that is appropriate for the 21st century. We have set challenging standards and targets in order to achieve this goal. As an exemplar for environmental sustainability, West Gorton will set the scene for Manchester’s Green City credentials. It will be a test-bed for our far reaching objectives and a centre of excellence for research, innovation and good practice. The new West Gorton will offer all the features that a family-friendly place should offer to be attractive to existing residents, newcomers and investors.
As part of this process, all partners are committed to innovation in the design of new housing, neighbourhood services and facilities, and the creation of functional green spaces and public realm. The structure of West Gorton and the mix of uses in the new neighbourhood are critical to get right for future generations. Manchester’s commitment to tackling climate change underpins our approach to development and design.

These spatial proposals are set out in a series of illustrations and form what is referred to as The Regulating Plan. This document sets out the physical, spatial, architectural, landscape and use standards for West Gorton. It knits together the transport, drainage and environmental parameters within one clear and deliverable plan. The regulating plan sets the ‘rules’ for street hierarchy and house types along with sustainable drainage solutions. The plan provides clear instructions to developers throughout the development process. Spatial Plan –Spatial planning includes all levels of land use planning from strategic and policy through to proposals. Master Plan – This phrase is interchangeable with the phrase spatial plan but it also gives more comprehensive guidance or instruction and encapsulates the comprehensive, long-term strategy.

// The Strategic Drivers / 1 Reputation The sustainability credentials of West Gorton and its proximity to the Regional Centre will create a new reputation for edge of city living, with a choice of housing types for different needs and lifestyles. This new reputation will grow from the investment in new local community facilities quality public realm, streets, spaces and simple workable designs in modern homes. The new parts of West Gorton will knit together with existing areas through public realm and streets that not just serve the needs of local people but also lift the spirits of all who use them. / 2 Mixing it up A wider mix and choice of houses are proposed , from terraces and larger homes as well as apartments overlooking new green spaces. A greater overall mix of types, sizes and tenures will be developed to bring new families and workers to this neighbourhood. / 3 Close to nature In West Gorton, green areas will be created and enhanced. New open spaces and park will provide attractive and welcoming modern, useable areas for all age groups, from local food production to a new green heart which offers play provision for children, sports areas and areas for peaceful reflection.
/ 4 Supporting community life Within walking distance there will be a new community hub where residents will find shops, a medical centre, offices, and community rooms. Armitage School and the climbing centre in the will be integrated into the master plan. These facilities and the new park will be within just a few minutes walk of each other. / 5 Safe and secure Defined streets and spaces will be overlooked. Every house will have a secure and protected garden and it will be clear which is public and private space. Natural surveillance will be utilised everywhere. Highways will be designed to manage traffic speed and ensure that commercial, through and local traffic is separated wherever possible. / 6 Moving around Streets and lanes will be legible and easily navigated by pedestrians and cyclists. Every street will be lined with homes and there will be no cul-de- sacs or dead spaces simply set aside for cars. The community hub, the school, parks, the local railway station and bus stops will all be accessible via pleasant pedestrian routes.

// Why have a Code? This document sets out proposals and standards that will secure the design, sustainable development and low carbon credentials of West Gorton. This is not about aesthetics or style. This code is about co-ordinating new phased house building, refurbishment of homes and investment in a new and existing green infrastructure to create a place within which people can thrive. The code integrates all aspects of place shaping and environmental targets simultaneously. It is about meeting multiple objectives through clear design standards and building in genuine sustainability from the beginning. This innovative approach will ensure the new West Gorton excels as a new low carbon community.
and a challenge to go further. It is a new approach to guiding the implementation of simple, best practice in design as a response to meaningful environmental performance targets. In short this code is intended to challenge and to be challenging.
Manchester City Council , New East Manchester, the Homes and Communities Agency and Guinness Trust Northern Counties Housing Association, have worked together to develop and agree targets and proposals outlined in this code. Communicating the new vision for West Gorton in a way that is clear, practical and engaging is essential. All those interested in West Gorton will be able to understand the core vision and how it can be delivered. The West Gorton Design Code sets out the vision and provides clear guidance and a flexible framework within which the right design, planning and development decisions can be made quickly and effectively. This document sets out specific design guidance and standards to meet challenging environmental targets and requirements which are more than a mere minimum requirement – they represent a starting point

// Chapter 3 // An Integrated Environmental and Spatial Plan
Prosperity in Manchester will depend on our ability to shape our communities, homes and lifestyles in order that they may successfully thrive in a low carbon future.
// Background
// How will our vision be achieved?
Climate change is a global problem and its negative impact on our living and working environments is already well documented. At international, national and regional levels, measures are being put in place to reduce CO2 emissions through the delivery of long-term mitigation strategies. To prepare communities for the impact of future climatic changes, effective adaptations are also being employed. The City’s ‘Call to Action’ climate change strategy and accompanying ‘Manchester: A Certain Future’ action plan underpin our environmental objectives for West Gorton. The action plan has two key objectives; to reduce Manchester’s CO2 emissions by 41% by 2020 from 2005 levels and to engage all individuals, neighbourhoods and organisations in Manchester in a process of cultural change that embeds ‘low carbon thinking’ into the lifestyles and operations of the city.
As an integral component of the Code, the Environmental Plan shows developers, their designers and other key stakeholders how the built form including, communal, residential, street and public realm, will respond to the West Gorton vision and how it will deliver a truly sustainable community. As with all of the details outlined in the Code, the environmental aspirations for the area have been built around the eight categories that make up the BREEAM Communities environmental assessment method. The standards on page 23 surpass those required by current regulations. The intention is to challenge the market to provide innovative solutions that address the sustainability objectives of our vision for West Gorton. Developers will need to demonstrate how their designs respond to these specific objectives and what contribution they make towards the broader holistic environmental vision for the area.
Any future designs for residential, commercial or community development in West Gorton will be required to respond fully to the City’s climate change strategy and correspondingly to other inter-related guidance including the Local Development Framework Core Strategy Planning Guidance around energy generation and Manchester’s Streetscape Manual which informs the design and management of new start trafficked streets. The Code’s Environmental Plan provides developers and designers with a way to ensure that future development proposals fully embrace the City’s environmental ambitions.
// DRAFT // A DESIGN CODE FOR WEST GORTON // DELIVERING MANCHESTER’S LOW CARBON NEIGHBOURHOOD

// Key elements of our vision Using each of the BREEAM Communities sustainability categories as a guide, the following details outline our overall aspirations for environmental excellence in West Gorton.
/ Climate change
/ Resources
It is estimated that during the next 40 years, Manchester could see peak summer temperatures increase in the range of 1 – 3 degrees centigrade. Temperature changes are expected to be coupled with increases in winter temperatures, a rise in winter rainfall and a greater incidence of storm events.
The effective management of resources will need to be considered at all stages of development including demolition, construction and the day to day usage of all buildings. Demolition contractors will adhere to the City’s guidelines for waste management of materials from sites and that all soil contaminants are dealt with appropriately – on site where possible. Building contractors will give consideration to material selection from recyclable and local sources and modern methods of construction. The management of water will be encouraged through design, for example the use of grey water systems for toilet flushing and garden/allotment irrigation. Waste management solutions will include approaches for composting and accessible, convenient locations for recycling to reduce the need to transport waste from residential areas to treatment sites.
All new development in West Gorton will have to play its part in responding to these expected climatic changes and in reducing harmful CO2 emissions that contribute to climate change. Responses will include: localised sustainable energy generation solutions (to be considered in line with planning guidance and the City’s aspiration to develop a sustainable city wide heat network); innovation in energy and water efficiency; a considered response to passive house design principles that will have a positive impact on reducing indoor temperatures in summer; the imaginative use of vegetation across developments to provide natural shading; and a range of Sustainable Urban Drainage solutions (SUD’s) to address the expected increase in the frequency of rain-bursts.

/ Transport
/ Ecology
/ Business
Through high quality public realm design and the creation of a hierarchy of streets, pedestrian and cycle friendly pathways will encourage walking and cycling as well as providing improved access to the various forms of public transport. Demand for cars could be met through links to local car hire schemes and electric charging points should be provided to facilitate this.
The network of green open spaces will promote outdoor recreation and social interaction whilst at the same time safeguarding and encouraging the development of a diverse insect and wildlife population through considerate planting and the choice of plant and tree species. Allotments provided to give residents the opportunity to grow their own food will also support wildlife/insect diversity. Green spaces, landscaping and water systems will be designed to deliver beautiful, pleasant areas which will encourage outdoor activities, while simultaneously providing benefits such as water filtration and purification, improved air quality and reduced noise.
West Gorton is home to over 20 small to medium size businesses, many of which provide local employment. Local businesses have their part to play in contributing to the area’s reduction targets for CO2 emissions, waste management, noise pollution and recycling. Business traffic throughout the area will be managed through the implementation of the new street hierarchy. Some existing local businesses have already adopted the City’s Environmental Business Pledge as a framework for reducing their CO2 emissions and a number have also become engaged with the Government’s Feed in Tariff initiative as a means of supplying locally generated power to the national grid.
Walking, running and cycling routes are identified in the spatial masterplan and place making principles as described above have informed the range of street designs for use of cars and commercial traffic. The street hierarchy recognises the importance of streets as places in their own right, not just transport corridors.
Given our environmental aspirations, West Gorton will provide opportunities for the creation of local green jobs, through the installation and maintenance of energy efficiency technologies, localised energy generation, local food production and cycle and car hire. In addition, the Village Hub will provide business space/job opportunities for local food sales, a grocer and a pharmacy to serve the neighbourhood.

Broadband Connectivity
Re-shaping the neighbourhood will create opportunities for resident interaction and activity through the provision of the Village Hub and high quality public realm that will foster recreation and social interaction. The neighbourhood will be better connected to the rest of the East Manchester area by improved and new pedestrian and cycle routes to public transport and other trails, pathways and cycle routes. The residents of West Gorton will be able to access the quality facilities east Manchester has to offer, e.g. the Academy High School, the Eastlands Sporting complex, public parks, local district centres and the near by city centre. All residents will be encouraged to embrace sustainable and healthy lifestyles that will engender a sense of pride in their green neighbourhood. Locations will be identified within the area where residents will be able to see examples of the benefits of low carbon living and receive advice and support in developing awareness of how they can enjoy and support the low carbon agenda.
West Gorton residents will benefit from new fibre optic technologies and future higher speeds of broadband. There will be a greater choice of internet providers and telecom connectivity will be future proofed through the provision of a secondary duct network (at street and plot level) at the same time that standard BT lines are installed. This will avoid future disruption to properties and increase the future capacity of internet access for the whole area.

The West Gorton community will benefit from a variety of green spaces, each designed to support and encourage different leisure and recreational opportunities. There will be a focus on green open areas, and strong planting related to the retention and rain gardens proposed as part of the SUDS system. Mature existing trees will be retained, where possible and new tree planting will be encouraged.
D Community Garden/Allotments The existing green space between Clowes Street and Ainsdale Street will be remodelled into community allotments. The existing trees will be retained. This area is designed to help support some of the lifestyle ambitions for West Gorton in terms of fitness, sustainable leisure and local food production.
These include:
E Green Streets All of the proposed streets will include road-side planting. Main streets will include grass lined open swales with tree planting. This will soften the main streets, and give an open green spacious feel as well as providing play opportunities in the street.
A Gregory Street Gardens This original Victorian garden remains intact and becomes the northern part of the proposed linear park that stretches south to Ainsdale Street. B Activity Zone This is a new green area designed to promote sporting activity and exercise and will contain a secure toddler’s play area, kick about and outdoor gym.
F Walking trail Proposals also include provision for a walking and fitness trail. This is a dedicated, way marked route which integrates all of the green spaces including the existing tree lined buffer zones on Hyde Road and Pottery Lane.
C Gorton Gardens A new formal garden will be created as a railed, quieter green space with seating and rest areas, adding a sense of reflection and retreat for the residents of West Gorton promoted.

/ Place shaping
/ Buildings
West Gorton will be an attractive place for people to live and visit. Development will provide a framework for the creation of a place with a green identity that is easy to travel around and that is connected to neighbouring areas.
The design of individual buildings will contribute to the sustainability of the overall development through the achievement of high environmental standards such as Code for Sustainable Homes (starting at and rising to level 6). All buildings in West Gorton will offer a healthy environment for occupants with good air quality, comfortable temperatures and low noise disturbance.
Development designs will contribute to the sense of place in ways that enhance quality lifestyles and well-being through, for example, a hierarchy of pedestrian and cycle friendly streets, high quality open space, house designs that reduce the negative impacts of noise and air pollution, active street frontages and defensible space.
Our homes will offer a healthy environment with good air quality, comfortable temperatures, low disturbance of noise and no impact of unhealthy substances from the ground, water, building materials or air. The quality of the indoor air in a building depends on several aspects, such as pollutants in the outdoor air, the ground, and building materials. A significant impact on the air quality derives from the occurrence of high humidity in the building construction, as this can cause problems with mould and smell. Careful control of humidity in the structure during construction and is essential. To ensure this the location, orientation, shape of the building and the design of its structure and shell must be performed in coherence with technical systems. An understanding of the needs of the occupants and how the building will be used is crucial in making the building function well. A residential building should also be able to offer a calm and private area for recreation whether that is a balcony or patio. For West Gorton, in total, to contribute to the exacting environmental targets, a more energy efficient, low carbon retrofit programme will be delivered across all retained homes. External enhancements, boundary treatments and new streetscapes will integrate existing and new homes and streets.
// DRAFT // A DESIGN CODE FOR WEST GORTON // DELIVERING MANCHESTER’S LOW CARBON NEIGHBOURHOOD
Noise is one of the most common causes of disagreements between neighbours. With this in mind, property design for both houses and apartments will exceed the building regulations requirements for airborne and impact sound in order to comply with the Code for Sustainable Homes assessment. Good practice should include examples of the following; approaches that keep services, stairs, lifts and circulation areas away from bedrooms, apartment corridors to have acoustically absorbent ceilings and floorways.

// Calculation of the Green Area Factor (Example) The Green Area Factor is the ecologically effective surface area divided by the total land area and the higher the value is, the better Green Area Factor score.
The ecologically effective area = coefficient*ecological area The coefficient depends on the permeability and the possibility for holding a varied biotope. The factors used to calculate the Green Area Factor are divided into two categories; coefficients that calculates green surfaces respective surface water. Example: The total area of a development is 479 sqm. 115 sqm is covered with green vegetation (coefficient 1.0) and 85 sqm is covered with mosaic paving (coefficient 0.3). The ecological effective surface area= 1.0 x 115+0.3 x 85=140.5 The Green Area Factor = 140.5/479=0.3

// Introduction
// The Plot Plan
This part of the document sets out the details of the code itself with regard to plots, houses, streets and the waste strategy.
The master plan is divided up into a sequence of plots. Each plot is colour coded corresponding to a particular approach, layout and treatment conveyed through the model houses described below.
The plot plan indicates the approach to different development plots across West Gorton and use of a variety of house types. There are five house types and the approach to refurbishment of retained homes will be co-ordinated and integrated with the new build. The approach to streets and how they accommodate cars, people, environmental features and contribute to new approaches to drainage is set out here.
// DRAFT // A DESIGN CODE FOR WEST GORTON // DELIVERING MANCHESTER’S LOW CARBON NEIGHBOURHOOD
Each plot has a different requirement/response, for example the location of terraces, villas, special corner turners, heights, placement and forms have been used. Similarly, different types of frontage and car parking can also be used to create variety. Each plot is also the basis for assessing how land assembly, procurement, financial viability and funding packages are co-ordinated.

The code contains a set of generic house types. These are not developed designs – they are intended to define scale and massing as well as a range of car parking solutions that can be used within the various development plots. The basic house types are therefore indicative. Developers are free to propose their own house type solutions and variations on their own products, subject to keeping to the spirit of what has been set out, with the aim of exceeding the standards and objectives that have been described here. However, variant proposals need to demonstrate how they address key plot arrangements, frontage and parking arrangements that are fundamental to the code.

This house arrangement can be made into a terrace or semi-detached. Its three storey simple frontage lends itself to creating simply lined and defined streets. Parking is located on the drive frontage which also contains a small structure for waste bins. The house plan is flexible and if required can be reduced to a three bed two storey or a five bed if the roof terrace is removed. The upper floor terrace can also be turned to face south.
This house arrangement can be made into a terrace or semidetached. In pairs the house can provide two parking spaces partially located behind the house frontage and within plot. This is a small two storey house which can be adapted to a larger size if required. The advantage of this arrangement is that back gardens are still secure from the front while also providing direct access to the garden and waste bins.
This house arrangement can be made into terrace or semi-detached villa. The house features a private entrance courtyard where parking is concealed and located behind the house frontage and screen wall which includes a roller gate for security. Waste bin storage is within the courtyard.

This house arrangement is ideal as part of a terrace. There is a continuous street frontage where parking is located inside the ground floor of the house. Parking on the ground floor automatically makes these house arrangement three storeys. The upper floor can be adapted for me bedrooms if required.
This house arrangement is designed to maximise smaller or awkward shaped plots. The house entrance is located on its longest side enabling the house to front a corner. Parking is located where possible either side of the house. The emphasis here is on creating a house form which lends a sense of meaning to key corners.
In order to contribute to the environmental targets for the neighbourhood, a retrofit programme will be delivered to the existing housing stock. This will be complimented by a green infrastructure including private gardens, boundary treatment and streetscape that will integrate the new residential developments with the current homes.

// Approach to new streets One of the primary design intentions underpinning the master plan has been the introduction of a number of short new streets which are designed to re-wire the existing disconnected street pattern. Together with the new streets, the existing streets/routes and spaces are remodelled into a network simple well defined streets which are designed to be safe, useable places in their own right. The new streets create: // A strongly defined division between public and private space which also ensures that every street is lined and overlooked by new homes. // A high quality public realm designed to foster a sense of pride and ownership in the community. // A more people-friendly environment which efficiently manages car access and parking. // A strong spatial and physical hierarchy between different streets creating character and variety. // A network of green and ecological corridors running throughout the new community as part of the SUDS and cooling strategy, whilst also adding to the overall green spaces across the area.
/ Street Hierarchy The Spatial plan proposes a range of street designs which are responses to the role and function of streets within the neighbourhood. West Gorton has been particularly affected by the conflict of business related traffic, local residential routes and movement on foot/cycle. The geometry and layout of the streets in West Gorton has been carefully considered to ensure that the streets provide a pleasant environment for the pedestrians, good connection to local services, and an improvement to the ecological nature of the area. Four street typologies are proposed, aiming to: // Slow vehicle speeds through residential areas. // Provide suitable parking provision. // Incorporate sustainable urban drainage solutions using swales and rills.
// DRAFT // A DESIGN CODE FOR WEST GORTON // DELIVERING MANCHESTER’S LOW CARBON NEIGHBOURHOOD
// Bennett Street will provide the main route for commercial traffic accessing the industrial sites and businesses in the West Gorton area. It will also be the bus route. // Main streets will form vehicular links between the residential areas and surrounding highways, and will be civic in nature. // Main streets will form vehicular links between the residential areas and surrounding highways. It is intended these streets will be 6.5m wide and allow for some on-street parking. In some instances swales line the edges of the streets separating footway and carriageway and providing a landscaped zone for pedestrians to move along.

// 24 SUDS –Dry Swales
// Sustainable Urban Drainage Systems (SUDS) All streets will be designed in the spirit of the Manchester Streetscape Manual and DfT’s Manual for Streets. A sustainable surface water drainage strategy is embedded into the design for West Gorton. This strategy will help reduce the risk of flooding by putting less strain on the public sewer network, increase biodiversity, and provide greater resilience to the challenges of climate change. Figure 27 (page 50) summarises the SUDS strategy across the West Gorton Plan. This has been tested in detail on the Gorton Villa Walk plot, as shown on figure 28. These SUDS features are described on figures 23 to 26, and summarised opposite. [The SUDS design is to be based on a 6 hour duration, 1:100 year storm event, as defined by BREEAM.]
/ Dry swales Dry swales are soft, grassy linear areas to hold water which evaporates and slowly drains away. The swales will: // Provide natural remediation to car parking runoff, reducing its pollution // Contain a filter drain at their base providing slow drainage outflow // Be approximately 4m wide, so that a 15m length provides 12m3 of storage // Have ecological value. The Construction Industry Research and Information Association (CIRIA) SUDS guide recommends a purpose grown amenity grade turf is generally appropriate.
// DRAFT // A DESIGN CODE FOR WEST GORTON // DELIVERING MANCHESTER’S LOW CARBON NEIGHBOURHOOD
55
// 25 SUDS –Rills /Rills Rills are open precast concrete channels to convey roof and road water. The rills will: // Have ‘V’ notches to provide some storage when raining // Typically 300mm deep x 250mm wide, providing 3m3 storage over 50m length // Have ecological value providing they do not dry out. Detention Basins are Vegetated depressions designed to provide flow control through attenuation of storm water runoff. They will normally remain dry except during and immediately after storm events and can function as recreational facilities. Planting should be resistant to water level changes and help minimise bank side erosion. Generally grass together with scattered scrubs is appropriate.

// 30 Waste collection – European models
// Waste Strategy A key feature of the long term environmental sustainability for West Gorton is the approach to waste management. We are looking to exceed the City Council’s current approach set out in “Waste Storage and Collection Guidance for New Developments “ (December 2008) Developers in West Gorton will be required to respond to this challenge by delivering waste management solutions for housing and apartment developments that will increase recycling activity and reduce waste whilst at the same time balancing their approaches with resident convenience and accessibility.
Developers are required to outline ways to rationalise the number of waste and recycling containers outside individual properties which can be both unsightly and inconvenient for householders. Centres should be sensitively located in places that are easily accessible and designed to conform to “Secured by Design” standards. Such an approach will facilitate more efficient waste collection and reduce the amount of collection traffic. Alternative methods of waste collection for disabled and elderly residents will need to be developed.
// DRAFT // A DESIGN CODE FOR WEST GORTON // DELIVERING MANCHESTER’S LOW CARBON NEIGHBOURHOOD
European models of waste collection should be explored including “Environment Houses”. These enable residents to dispose of their household refuse and recyclable products via specified access points outside and within the building. Design standards for environment houses incorporate a green roof, solar panels, and rainwater harvesting. They are well lit and include a sink to allow containers to be washed. This is just one approach to waste management and developers will be expected to explore a range of alternative options.

// Summary West Gorton is a neighbourhood set to change. Investment in quality new homes and facilities will contribute to the City’s targets for ambitious CO2 reductions. This document sets out the challenge to developers in some detail and at the same time we are seeking innovation in response to this code. New streets, new approaches to drainage, open space and waste collection are all aspects of the code that demand high quality design to ensure environmental targets are not just met but exceeded within the next ten years.
