Where It’s At
Site Appraisal


Sustainable construction starts well before the first stone or brick is laid, or even the first line on a drawing. The ability to ‘understand’ a site, and its surroundings, is a key skill. This will include thinking about how the site has been used in the past and could be used in the future.

The natural features of the site, any assets and value come next. Biodiversity, micro-climate, existing structures, aspect, views into and out of the site, local community needs, surrounding design styles, development patterns and neighbours, features above and below ground (eg archaeology, minerals, water), potential contamination, topography, the catchment context, and access to the site are all relevant. It makes sense to gather and analyse economic, community and environmental information about a site and its surroundings and to consider the historical context in which it sits prior to the design phase of the development.


Key Questions

  • Have you checked on the provisions of the development plan (structure, unitary and local plans)?

  • Has an appraisal of the site (including economic, social, cultural and environmental issues) and its setting been done? Has it been summarised in a clear schematic diagram and shared with the planning authority and other interested parties?

  • Have you been able to explain clearly how your development will maximise the opportunities and overcome the constraints of the site and its surroundings?

  • Have appropriate archaeological and historic appraisals of the scheme taken place? (eg a watching brief at the groundwork stage or more ongoing assessment)

  • To what extent have the community and its representatives and other specialist interest groups been involved in survey and analysis of the site and the proposed design?

  • Have other options for development of the site been considered and is there a clear justification (in sustainable development terms) for the chosen option?


Benefits

  • ‘Understanding’ the site and its surroundings will benefit the design of the development - now and for the future

  • A clear demonstration of how the development makes best, sustainable use of the site and its surroundings will improve the chances of success with the local planning authority, the local community, and site neighbours

  • Expensive mistakes and unnecessary waste will be avoided (eg through appropriate incorporation of existing structures)

  • The appraisal may bring up exciting new ideas and opportunities
