The first days of autumn and the TUGC team were hard at work in North London re-instating 440 sq.m. of wildflower roof after alterations to a standing seam roof on a Royal Mail depot.


The build up included 16 tonnes of substrate, 12 tonnes of wildflower turf and Aquaten fleece was added to improve the water attenuation on the roof as well as providing a passive irrigation system to the vegetation.
