Good Practice Guidance - Sustainable Design and Construction

The purpose of the planning system is to contribute to the achievement of sustainable development ...

... To achieve sustainable development, economic, social and environmental gains should be sought jointly and simultaneously through the planning system ...

... Good design is a key aspect of sustainable development, is indivisible from good planning, and should contribute positively to making places better for people ...

... Local planning authorities should adopt proactive strategies to mitigate and adapt to climate change, taking full account of flood risk, coastal change and water supply and demand considerations ...

Annex 1 Example Policies on Sustainable Design and Construction (including relevant extracts from Inspectors reports)


The examples in this annex are of local plan policies that have been adopted, together with relevant extracts from the inspectors/examiners report. They should not be viewed as model policies, as what is appropriate in any given area will depend on local circumstances and evidence. However, they may be useful as examples of policy approaches that have been judged sound.

Residential conversions and changes of use are also required to achieve high standards, reflecting the impact of existing buildings on the UKs carbon footprint.
