The reconfiguration of the back of our own house included the renovation of an existing uninsulated balcony roof over an off-shot cloakroom and utility space. We decided it was a good location for a small green roof as it is overlooked by bedroom windows, is relatively easily accessible from a level area in the garden and faces South West. We wanted to create a low maintenance green roof, attracting insects and birds, and to test different types of planting. 

We set out intending to source all our materials locally, but unfortunately, we simply couldn’t find a local supplier who was able to provide the very small amounts we needed. Therefore, our roof design combines a mixture of proprietary green roof materials from specialist suppliers and locally sourced materials such as timber edging, peat-free compost and plants.

At the outset, we wanted to source all our materials locally, but it soon became apparent that this would not be feasible in the small amounts we needed. Therefore our roof combines a mixture of proprietary green roof materials from specialist suppliers and locally sourced materials and plants. Once waterproofed by our builders, it took a couple of days to build the green roof, including apply the growing media and the initial planting and seeding.

The roof is a test bed to try different types of planting. Over the last two years we have planted bulbs (including chives, muscari and iris), low growing sedum varieties, sempervivums (house leek) and wildflower seed.  
We're very happy with the results so far and record the successes and failures on this website and social media.  Contact us if you would like a specification for a similar roof; we would be happy to talk it through with you.
