What Houzz contributors are saying:
How much will it cost?Prices vary hugely, but generally plugs cost more than blankets – think of the labour involved in installing individual plants – but wildflower and sedum roofs are roughly comparable. Companies such as Sky Garden offer a supply-only option, so you can fit the roof yourself. As a rough guide, supply-only blanket green roofs from Sky Garden cost from £120 per sq m, while a blanket plus installation would cost from £336 per sq m.
