Gabions and cyclamen, a new green roof in Herne Hill

It’s taken a little while to share this new green roof I built in Herne Hill recently.

There were a number of challenges here particularly the height of the roof with no edge protection, we used a harness to install the edges.

The edges were built using gabion cages filled with cobbles. This created a more natural edge and ensured the stones didn’t roll off the edge of the roof and shatter the tiles below, I think they look pretty cool.

I used aerated clay pebbles for the drainage layer again, really like these rather than the plastic sheets and carrying a bag makes you feel really strong as they are so lightweight. We then put in a protective membrane and covered with ultra lightweight green roof substrate from Shire Substrates.

The roof has been seeded with a mixture of wildflowers and grasses with more to be added in the spring. In the meantime I put in some grasses, sedums and also Cyclamen. I wasn’t really sure about the cyclamen but not much else is flowering this time of year a month later and they seem to have settled in well.

I will add further updates in the spring. There are lots of bulbs in there which should appear soon.
