Vista is the second of the exemplar Carbon Challenge sites being delivered by the Homes and Communities Agency (HCA). The Carbon Challenge programme aims to deliver communities which embody best practice in sustainable design, construction and operation. They will act as test beds for the construction industry and inform future policymaking. The 7ha South Bank development will incorporate 295 dwellings of mixed types, green spaces and additional mixed use elements. Every dwelling on site must meet the highest level of the Code for Sustainable Homes (CSH): Level 6, which is ‘zero carbon’ (with allowable solutions).
