Case Study - Tarn Hows , Lake District
The build is in a SSSI (Site of special scientific interest) which is owned by the national trust building is a visitor center and toilet block for site. The green roof helped to blend the building into the site as well as reducing the build impact on the site. Because the building is located in a SSI the roof had to be planted with native sedums
