Bespoke Biodiverse Green Roofs

When to specify...

Biodiverse roofs are designed to create a wide range of different habitats. This includes undulating substrates, piles of stone and dead wood, bare sandy areas and dew ponds. This matrix of different habitat allows the broadest range of flora and fauna to thrive. Bauder have worked with Buglife to produce specifications that ensure the roof areas maximize their ecological potential.
