Policy D3 Optimising site capacity through the design-led approach The design-led approach A All development must make the best use of land by following a designled approach that optimises the capacity of sites, including site allocations. Optimising site capacity means ensuring that development is of the most appropriate form and land use for the site. The design-led approach requires consideration of design options to determine the most appropriate form of development that responds to a site’s context and capacity for growth, and existing and planned supporting infrastructure capacity (as set out in Policy D2 Infrastructure requirements for sustainable densities ), and that best delivers the requirements set out in Part D. B Higher density developments should generally be promoted in locations that are well connected to jobs, services, infrastructure and amenities by public transport, walking and cycling, in accordance with Policy D2 Infrastructure requirements for sustainable densities . Where these locations have existing areas of high density buildings, expansion of the areas should be positively considered by Boroughs where appropriate. This could also include expanding Opportunity Area boundaries where appropriate. C In other areas, incremental densification should be actively encouraged by Boroughs to achieve a change in densities in the most appropriate way. This should be interpreted in the context of Policy H2 . D Development proposals should: Form and layout 1) enhance local context by delivering buildings and spaces that positively respond to local distinctiveness through their layout, orientation, scale, appearance and shape, with due regard to existing and emerging street hierarchy, building types, forms and proportions 2) encourage and facilitate active travel with convenient and inclusive pedestrian and cycling routes, crossing points, cycle parking, and legible entrances to buildings, that are aligned with peoples’ movement patterns and desire lines in the area 3) be street-based with clearly defined public and private environments 4) facilitate efficient servicing and maintenance of buildings and the public realm, as well as deliveries, that minimise negative impacts on the environment, public realm and vulnerable road users Experience 5) achieve safe, secure and inclusive environments 6) provide active frontages and positive reciprocal relationships between what happens inside the buildings and outside in the public realm to generate liveliness and interest 7) deliver appropriate outlook, privacy and amenity 8) provide conveniently located green and open spaces for social interaction, play, relaxation and physical activity 9) help prevent or mitigate the impacts of noise and poor air quality 10) achieve indoor and outdoor environments that are comfortable and inviting for people to use Quality and character 11) respond to the existing character of a place by identifying the special and valued features and characteristics that are unique to the locality and respect, enhance and utilise the heritage assets and architectural features that contribute towards the local character 12) be of high quality, with architecture that pays attention to detail, and gives thorough consideration to the practicality of use, flexibility, safety and building lifespan through appropriate construction methods and the use of attractive, robust materials which weather and mature well 13) aim for high sustainability standards (with reference to the policies within London Plan Chapters 8 and 9 ) and take into account the principles of the circular economy 14) provide spaces and buildings that maximise opportunities for urban greening to create attractive resilient places that can also help the management of surface water. E Where development parameters for allocated sites have been set out in a Development Plan, development proposals that do not accord with the site capacity in a site allocation can be refused for this reason. 3.3.1 For London to accommodate the growth identified in this Plan in an inclusive and responsible way every new development needs to make the most efficient use of land by optimising site capacity. This means ensuring the development’s form is the most appropriate for the site and land uses meet identified needs. The optimum capacity for a site does not mean the maximum capacity; it may be that a lower density development – such as gypsy and traveller pitches – is the optimum development for the site. 3.3.2 A design-led approach to optimising site capacity should be based on an evaluation of the site’s attributes, its surrounding context and its capacity for growth to determine the appropriate form of development for that site. 3.3.3 The area assessment required by Part A of Policy D1 London’s form, character and capacity for growth , coupled with an area’s assessed capacity for growth as required by Part B of Policy D1 London’s form, character and capacity for growth , will assist in understanding a site’s context and determining what form of development is most appropriate for a site. Design options for the site should be assessed to ensure the proposed development best delivers the design outcomes in Part D of this policy. 3.3.4 Designating appropriate development capacities through site allocations enables boroughs to proactively optimise the capacity of strategic sites through a consultative design-led approach that allows for meaningful engagement and collaboration with local communities, organisations and businesses. 3.3.5 Developers should have regard to designated development capacities in allocated sites and ensure that the design-led approach to optimising capacity on unallocated sites is carefully applied when formulating bids for development sites. The sum paid for a development site is not a relevant consideration in determining acceptable densities and any overpayments cannot be recouped through compromised design or reduced planning obligations. 3.3.6 GooLondon Plan Policy D3 · official source →
