Just a quick one, not finished yet but the roof is progressing nicely, we have the sedum in place for the middle of the roof and drainage channels laid out in pebbles across the rest of the roof.
Now all we have to do is add in soil from the garden in the gaps so it will grow a range of native plants. As this will involve a fair bit of lifting we are going to get some people round for a green roof party and they will all help moving the stuff about.
