Green roof in South London

Last week I completed another green roof in Streatham. It is on the rear of a really interesting house, a 1930s semi that is getting a complete eco-makeover from the owner. He has insulated the walls inside and out with wood fibre and remade the roof in solar panels and that is just the start. All Stephen’s neighbours find it hard to believe how warm the house is without loads of heating!

Anyway, last Wednesday he set aside so I could come along and help him build a green roof, here are the photos:
