03.2 Highways design

In 2015 Rootstock were appointed to work with Kier and Transport for London to redesign two major roundabouts and a highway in south London. The brief was to remove the tired, monolithic palette of shrubs and design a landscape with rich and diverse canopy levels and colours throughout the year, maximising the opportunities for wildlife and people. All three sites suffer from high levels of soil contamination that has accumulated from exhaust deposits and are in exposed, windy, dry and warm locations.

Rootstock carried out detailed research to identify a palette of plants that tolerate this combination of stresses, drawing on academic literature, field observations and our own plant database. The planting will be carried out in Autumn 2016.
