Case study on-site learning: One Brighton

In November 2015 UK-GBC (with Bioregional and Feilden Clegg Bradley Studios) took a group of our members around BioRegional’s exemplar sustainable development, One Brighton.

This 172 apartment eco complex with café, community space and offices in the heart of Brighton, was created by applying the principles of One Planet Living to a large residential development but also using the sustainability learnings from the BedZed eco-village, one of the first sustainable residential developments in the UK.

The five years of post occupancy evaluation data indicate this project could be one of the most sustainable urban communities in Europe.
