    INTRODUCTION                                                SUSTAINABLE DESIGN


    The purpose of this SPD is to provide guidance              The overriding objective is to deliver sustainable

    across a number of policies – where relevant these
    are highlighted at the start of each chapter of this SPD.

    Whilst the policies contained within the Local Plan
    and the Core Strategy are preeminent in determining
    planning applications it is recognised that Government
    policy has changed significantly since the Local Plan
    was adopted in 2003. The Residential Design Guide
    has therefore been developed with consideration
    of national policy and guidance, notably PPS1:
    Delivering Sustainable Development and PPS1

    Supplement: Planning and Climate Change and
    PPS3: Housing. Recent changes have also meant
    that the RDG has been developed in accordance
    with the National Planning Policy Framework (NPPF).

    It is anticipated that many of the Local Plan
    policies will be replaced in the forthcoming
    Development Management Development Plan
    Document. At an appropriate stage in the
    development of the Development Management
    DPD this SPD will be updated to reflect new policy.

    The SPD and its objectives also relate to the
    Core Strategy, notably the following policies:

    BUILDING FOR LIFE AND LIFETIME
    HOMES


    Lifetime Homes incorporates 16 design criteria
    to ensure homes are more flexible and inclusive
    to support the changing needs of individuals and
    families at different stages of life. The criteria also
    help to meet the Council’s objectives of sustainable
    design, architectural quality and inclusive design.
    The Council, therefore, intend to make Lifetime
    Homes mandatory for all newly built or converted
    housing.

    Relevant criteria are listed at the start of each chapter,
    highlighted in purple with the Lifetime Homes logo.
    The criteria may be found at www.lifetimehomes.
    org.uk.

    Building for Life (BfL) is a method for measuring the
    design quality of residential developments. It sets
    the national standard for residential design with its
    Silver Standard being awarded to schemes which
    score over 16 out of 20 against its criteria and Gold
    Standard which score over 16 out of 20. The scheme
    is led by The Commission for Architecture and the
    Built Environment (CABE) and the House Builders
    Federation. It involves assessing the quality of
    schemes by asking 20 questions which cover four
    subject areas:

    Part I - Environment and Community

    Part II - Character

    Part III - Streets, parking and pedestrianisation

    Part IV - Design and Construction.

    This SPD complements Building for Life. The
    following chapters relate closely to BfL’s subject
    areas and questions, and it is intended that the SPD
    will result in a quality of design which will meet the
    design standards set by BfL. At the start of each
    chapter a box, highlighted in blue with the BfL logo,
    sets out which BfL criteria relate to the contents of
    the chapter. All major applications will be assessed
    against the Building for Life criteria and we would
    advise developers to ensure that their Design and
    Access Statements contain sufficient information to
    allow a full appraisal of the proposals.

    The outcome of the BfL assessment will be reported
    to the Planning Committee.

3   Design Process
    INTRODUCTION


    The delivery of high quality development is dependant
    upon a process which takes all the relevant design
    issues into account at the earliest possible stages.
    This chapter sets out the design process that
    developers will be expected to demonstrate they
    have undertaken to ensure that proposals make
    adequate consideration of site constraints and
    opportunities and are locally distinctive.



    POLICY BACKGROUND


    Circular 1/2006 states that ‘an applicant should
    understand the context in which their proposal
    will sit, and use this understanding to draw up the
    application’ (para 97). The Circular suggests that
    in order to fully understand the context applicants
    should follow a design process which includes:

    assessment of the site and relevant planning
    policies; involvement (with local authority and
    community);evaluation; and Design of the scheme
    using the assessment, involvement and evaluation
    information collected.                                   SUSTAINABLE DESIGN
    The diagram (Figure 2.1) sets out the Council’s
    guidance on this design process, indicating how
    the chapters of this                                     The developers’ approach to sustainability must be

    A critical element in the process is pre-application
    negotiation, which seeks to agree the design of
    proposals prior to applications being submitted
    for planning permission. To ensure a design which
    has officer support at the time of submission,
    prospective developers should follow the design
    procedure outlined in Figure 3.1

    CONTEXT AND SITE APPRAISAL


    PLANNING POLICY

    Prospective developers should ask:

    • Is the site allocated for housing development in
    the development plan? An unallocated site may not
    be suitable for residential development in principle.

    • Is there any adopted Area Action Plan, SPD,
    Masterplan, development brief or other guidance
    for or relevant to the site? Development principles in
    these documents will need to be followed.

    • Are there any designations on the site or nearby,
    for example Conservation Area or Valley park, which

    The plan should also include the existing utility
    connections to the site, and in particular potential

    which are close to existing decentralised energy

    be expected to connect to these. An assessment

    electricity or heat) to the surrounding area should be

    PERIMETER BLOCKS


    Perimeter blocks (Figure 5.1) are an arrangement
    of buildings that enclose places such as streets
    and squares. They assist in achieving sustainable
    development by creating layouts which have good
    links between places and hence the potential to
    reduce vehicle movements and encourage walking
    and cycling. They may consist of houses or flats but
    all will create a clear building line with a well articulated
    frontage to the public realm while containing
    private space to the rear. Built to a consistent and

    In cases of formal layouts, based largely on the use
    of right angles, the creation of continuous building
    lines and avoidance of left-over spaces is relatively
    straightforward. Informal layouts will require more
    care and a flexible approach to house design to
    avoid disjointed and poorly enclosed streetscape.

    LANDSCAPE FRAMEWORK

    A LANDSCAPE FRAMEWORK IS REQUIRED FOR
    LAYOUTS ON MOST SITES.

    This will demonstrate how the proposed landscape
    will connect to the wider landscape and ensure a
    good relationship between buildings and spaces.
    The existing landscape will often be the starting point
    for the design with the framework setting out the
    structure of the site, how existing and proposed views
    will be accommodated, and how the management of
    water and biodiversity (existing habitat, connections
    to off-site landscape/ecosystems) will be integrated
    into the development.

    The landscape framework for a site must ensure
    that the various components of landscape, such
    as public open space, play areas, woodland,
    hedgerows, wildlife habitats and green lanes are
    well connected to each other Site development
    should contribute to the Green Infrastructure of
    the settlement and underpin the landscape of the
    site. Underground services, sustainable drainage
    systems and circulation and access arrangements
    should be integrated into the framework. Figure 5.12
    is an example of how a landscape framework may
    be presented.

    This will show street pattern, distribution and size
    of open space and how places within the site
    are connected. The principles of built form and
    enclosure will be demonstrated without the detail of
    individual buildings or landscape. Connections to
    the surrounding area should be clearly set out to
    demonstrate how these are to be achieved. Figure
    5.13 is an example of how such a plan may be
    presented.

    LAYOUT PLAN

    A DETAILED LAYOUT PLAN MUST BE PROVIDED.

    The layout plan is a detailed plan which
    demonstrates how all the site’s facilities, including
    individual dwellings, parking, underground services,
    bin storage and other utilities are accommodated.
    The layout plan should show how the development
    will deliver the principles set out in the concept
    plan, landscape framework and block plan and
    demonstrate how the site will work in practical terms.

    Places within a layout should be mindful of increasing

    an important role in providing attractive levels of
    summer shade which will become increasingly
    important as summer temperatures rise.

    SQUARES

    Squares are well recognised and appreciated
    components of urban form. They contrast with
    the linear nature of streets and lanes and act as a
    focal or reference point in a townscape. They help
    create a strong sense of place and also provide
    good opportunities for social interaction and may
    accommodate public open space and car parking
    effectively without damaging the townscape or
    amenity. An effective square may be large with
    imposing buildings (Figure 5.7) or small creating a                 Figure 5.8 An attractive intimate square.

    LIFETIME HOMES RELEVANT CRITERIA:1. CAR PARKING WIDTH;   As has been previously discussed the Council’s
    2. ACCESS FROM CAR PARKING.                              approach to the layout of new developments is
                                                             to facilitate a sustainable transport hierarchy that
    BUILDING FOR LIFE RELEVANT QUESTIONS;11, 12, 13, 16      prioritises pedestrians, cyclists and public transport
                                                             over private vehicle use. However, the Council
    INTRODUCTION                                             also recognises the need to provide adequate car
                                                             parking within new developments as set out in the
                                                             Parking Guidelines document, to a maximum of 1.5
                                                             spaces per dwelling.
    This chapter sets out the Council’s preferred
    approach for the provision of car and cycle parking
    within residential developments. The council’s
    approach to car parking has been developed
    through an understanding of car ownership patterns
    (based on the 2001 census) and national research
    and guidance.

    The following guidelines will be applied to all
    development unless the Council is satisfied that
    a source has been specifically designed to be an
    exceptional sustainable development which avoids
    the provision of car parking adjacent or close to
    dwellings within the main layout (such as Vauban,        Figure 7.1 Car free environment in Vauban, Freiburg, Germany.

    Frieburg). The provision of Car Club spaces within
                                                             Research indicates that the way parking is provided
    developments is encouraged.
                                                             within a development is as important as the number
                                                             of spaces provided. Poor provision of parking
    POLICY BACKGROUND                                        has a significant impact on the quality of streets
                                                             and spaces. “Residential Car Parking Research”
                                                             (DCLG 2007) reviews national car ownership
    The guidance set out in this chapter provides            patterns and the issues relating to allocated and
    guidance on the interpretation of the following saved    unallocated parking. It suggests that Local Planning
    policies from the Local Plan:                            Authorities may wish to develop specific guidance
                                                             regarding the provision of car parking. The evidence
    T2 Access to Development                                 suggests a direct link between dwelling size and
                                                             car ownership which has been developed into the
    T6 Pedestrian Routes and Footpaths                       detailed guidance below.

    T8 Cyclists and Development

    T19 Car Parking Provision and Standards

    DS1 Development Standards

    DS3 Planning Out Crime

    H8 Housing Design & Housing Mix

    It is anticipated that many of these policies will
    be replaced in the forthcoming Development
    Management Development Plan Document. At an
    appropriate stage in the development of the DPD
    this SPD will be updated to reflect new policy.

However weather patterns (hotter, drier summers and many of the issues highlighted in the objectives cut wetter winters with more extreme weather events). across a number of policies – where relevant these are highlighted at the start of each chapter of this SPD. Whilst the policies contained within the Local Plan and the Core Strategy are preeminent in determining planning applications it is recognised that Government policy has changed significantly since the Local Plan was adopted in 2003. The Residential Design Guide has therefore been developed with consideration of national policy and guidance, notably PPS1: Delivering Sustainable Development and PPS1 Figure 2.1 Residential development which expresses its sustainable design. Supplement: Planning and Climate Change and PPS3: Housing. Recent changes have also meant that the RDG has been developed in accordance with the National Planning Policy Framework (NPPF). It is anticipated that many of the Local Plan policies will be replaced in the forthcoming Development Management Development Plan Document. At an appropriate stage in the development of the Development Management DPD this SPD will be updated to reflect new policy. The SPD and its objectives also relate to the Core Strategy, notably the following policies: 8 North Lincolnshire Residential Design Guide

  • 10. 2 Design Objectives BUILDING FOR LIFE AND LIFETIME HOMES Lifetime Homes incorporates 16 design criteria to ensure homes are more flexible and inclusive to support the changing needs of individuals and families at different stages of life. The criteria also help to meet the Council’s objectives of sustainable design, architectural quality and inclusive design. The Council, therefore, intend to make Lifetime Homes mandatory for all newly built or converted housing. Relevant criteria are listed at the start of each chapter, highlighted in purple with the Lifetime Homes logo. The criteria may be found at www.lifetimehomes. org.uk. Building for Life (BfL) is a method for measuring the design quality of residential developments. It sets the national standard for residential design with its Silver Standard being awarded to schemes which score over 16 out of 20 against its criteria and Gold Standard which score over 16 out of 20. The scheme is led by The Commission for Architecture and the Built Environment (CABE) and the House Builders Federation. It involves assessing the quality of schemes by asking 20 questions which cover four subject areas: Part I - Environment and Community Part II - Character Part III - Streets, parking and pedestrianisation Part IV - Design and Construction. This SPD complements Building for Life. The following chapters relate closely to BfL’s subject areas and questions, and it is intended that the SPD will result in a quality of design which will meet the design standards set by BfL. At the start of each chapter a box, highlighted in blue with the BfL logo, sets out which BfL criteria relate to the contents of the chapter. All major applications will be assessed against the Building for Life criteria and we would advise developers to ensure that their Design and Access Statements contain sufficient information to allow a full appraisal of the proposals. The outcome of the BfL assessment will be reported to the Planning Committee. 10 North Lincolnshire Residential Design Guide

  • 14. 3 Design Process INTRODUCTION The delivery of high quality development is dependant upon a process which takes all the relevant design issues into account at the earliest possible stages. This chapter sets out the design process that developers will be expected to demonstrate they have undertaken to ensure that proposals make adequate consideration of site constraints and opportunities and are locally distinctive. POLICY BACKGROUND Circular 1/2006 states that ‘an applicant should understand the context in which their proposal will sit, and use this understanding to draw up the application’ (para 97). The Circular suggests that in order to fully understand the context applicants should follow a design process which includes: assessment of the site and relevant planning policies; involvement (with local authority and community);evaluation; and Design of the scheme using the assessment, involvement and evaluation information collected. SUSTAINABLE DESIGN The diagram (Figure 2.1) sets out the Council’s guidance on this design process, indicating how the chapters of this The developers’ approach to sustainability must be set out at the start of the design process to ensure document inform each stage of the process. that opportunities to reduce energy consumption Following this design process will help to ensure that and carbon emissions, integrate green infrastructure the applicant meets the requirements of policy DS1 and improve biodiversity are taken. in the saved Local Plan and Policy CS5 of the Core Strategy, which requires the proposals to consist of Sustainable Design must be at the heart of the locally distinctive, sustainable designs. design process, and should look at the whole site, not just the proposed buildings.

A critical element in the process is pre-application negotiation, which seeks to agree the design of proposals prior to applications being submitted for planning permission. To ensure a design which has officer support at the time of submission, prospective developers should follow the design procedure outlined in Figure 3.1 14 North Lincolnshire Residential Design Guide

This will demonstrate how the proposed landscape will connect to the wider landscape and ensure a good relationship between buildings and spaces. The existing landscape will often be the starting point for the design with the framework setting out the structure of the site, how existing and proposed views will be accommodated, and how the management of water and biodiversity (existing habitat, connections to off-site landscape/ecosystems) will be integrated into the development. The landscape framework for a site must ensure that the various components of landscape, such as public open space, play areas, woodland, hedgerows, wildlife habitats and green lanes are well connected to each other Site development should contribute to the Green Infrastructure of the settlement and underpin the landscape of the site. Underground services, sustainable drainage systems and circulation and access arrangements should be integrated into the framework.

Some places such as key pedestrian and cycle routes will be vehicle free, but most good places are those that accommodate the movement and parking of vehicles at the same time as creating a pedestrian friendly and attractive public realm. (IV) SUMMER SHADING Figure 5.1 A strong sense of place created by a formal, planned character. Places within a layout should be mindful of increasing summer temperatures due to unavoidable climate change resulting from past and forecast CO2 emissions. Building form, trees and plants play an important role in providing attractive levels of summer shade which will become increasingly important as summer temperatures rise.

It is important that the trees have sufficient space to grow to a reasonable size without affecting residential amenity and to allow vehicles to move through and to park without adversely affecting the trees. Figure 5.6 indicates the space and distances needed to accommodate trees. To create a good quality avenue with a good balance between the heights of buildings and spaces they face three storey buildings will often be required in conjunction with appropriate species of trees. Carriageway widths may need to take account of large vehicles (e.g. bus routes). Parallel on street parking may be required. Figure 5.6 illustrates how Figure 5.3 Layout based on the use of culs-de-sac. this may be achieved: Figure 5.5 An avenue within a residential area.

They contrast with the linear nature of streets and lanes and act as a focal or reference point in a townscape. They help create a strong sense of place and also provide good opportunities for social interaction and may accommodate public open space and car parking effectively without damaging the townscape or amenity. An effective square may be large with imposing buildings (Figure 5.7) or small creating a Figure 5.8 An attractive intimate square. sense of intimacy (Figure 5.8). Careful consideration needs to be given to the size of a square, the nature of the buildings facing onto it and the ways in and out of the space and across it. Footpaths and cycleways should follow desire lines – this avoids damage to planting through people forging their own routes. Figure 5.7 A large green square within a residential development.

  • 44. 6 Places Within a Layout PUBLIC OPEN SPACE The provision of public open space (Figure 5.17) should be considered as an integral part of the design of a layout. As well as meeting the technical requirements specified in planning policy and in the Council’s adopted Public Open Space SPG, the spaces also need to form part of the landscape infrastructure, be attractive, safe, well maintained and enhance biodiversity. It is essential that developers consider the location, extent and function of public open space at the start of the design process. Figure 5.15 An example of a block layout based on lane/mews concept (with integral garages). These places should maintain the principle of providing active frontages (at ground floor as well as upper floors). Mews streets or courts should not be based on the use of flats over garages (FOGS).

There may be good townscape reasons for this approach but it is important that elevations are uncluttered and that footway materials directly abut the building. Any need for the delineation of adopted and private surfaces should be unobtrusive and Figure 5.18a This arrangement of two storey houses produces a height to width ratio minimal. Rows of Studs or setts may be appropriate. of 1:3 but the enclosure and townscape is likely to be poor.

Large bay, oriel and dormer windows and chimneys front gardens may not be appropriate because they may reduce densities, but with sufficient space they allow scope for planting, sitting out and informal social interaction. If front gardens are to be used for bin storage it is important that structures accommodating them are integrated into the design and screened by front and party walls and that in accommodating bins sufficient space is allowed for planting.

However, the Council INTRODUCTION also recognises the need to provide adequate car parking within new developments as set out in the Parking Guidelines document, to a maximum of 1.5 spaces per dwelling. This chapter sets out the Council’s preferred approach for the provision of car and cycle parking within residential developments. The council’s approach to car parking has been developed through an understanding of car ownership patterns (based on the 2001 census) and national research and guidance. The following guidelines will be applied to all development unless the Council is satisfied that a source has been specifically designed to be an exceptional sustainable development which avoids the provision of car parking adjacent or close to dwellings within the main layout (such as Vauban, Figure 7.1 Car free environment in Vauban, Freiburg, Germany.
