Not all my green roofs are in London, you can see one of my early ones in Welwyn Garden City and this magnificent roof on a garage in Spring Gardens in Marlow
The roof was installed early this year using Shire substrates and materials from Optigreen. I used expanded clay for the drainage layer and large cobbles to create a more natural looking border.
The roof had loads of really nice seeds in it and was also planted with some sedums, aliums and stipa grasses and it has really blossomed tremendously.
