This is one that’s growing right now. I built it with the kids using leftover materials from other jobs and an old pallet to stand in for the roof. The rocks in gabion cages look great and it is super green but lacking in the wildflowers that we seeded it with.
Another one on a new extension this one was specified with a sedum mat. Ever keen to increase biodiversity I also sowed it with wildflower seeds. I quite like it as a way to put the roof together, very simple and also quick, if a bit heavy getting the mat up to the roof. The sedum roofs often die out quickly but this one has a good layer of substrate underneath for it to grow into which should retain water and increase resilience.
This is a small green roof on a modern house in Sydenham Hill. It uses white painted railway sleepers for a frame to match the fascia boards on the house and I think fits in very well.
This was a green roof on a new extension built from reclaimed bricks. The roof had a slope on it meaning we used a different drainage system that also helped retain the soil in place. It also had a watering system added at the top of the slope for the dryer months.
This was a really cool extension using reclaimed materials in Hackney. The green roof was a bit tricky to photograph but you can see the effect of the plants blowing in the wind above the skylight.
A 2 section green roof installed in Highgate as part of an Eco retrofit being carried out at the property. We incorporated reclaimed york stone paving slabs to create a path which was lined with lemon thyme that should grow over it and release a fragrance when trodden on. Some of the existing planters were retained and we used lots of grasses and some saffron crocuses.
This was a tiny green roof built as part of a refurb a friend was doing in Stoke Newington. Some nice plants from New Covent Garden and great to have some builders on site to carry all the soil upstairs.
This is a project I completed back in October, secure cycle storage and a green roof. The client wanted secure storage in the front garden without having a big ugly box taking up all the space for planting and we came up with this elegant solution.
As the shed is on the way into the house we planted a number of different herbs which can be easily picked when you are on the way home and also release a scent if you brush past. These were combined with some flowering plants (it was October so not much available) and sedums. The whole roof was also sown with wildflower seeds so should be quite productive in the spring. There are saffron crocus bulbs underneath which may start to appear in late summer.
The bike shed itself has capacity for 2 bikes but there is a larger 4 bike version or these can be put side by side for multiples. To order.
This type of roof can be more easily accessed by the householder so we can try and create a slightly more formal garden than I would on a normal green roof as you can change the plants around and water and feed them if it is necessary.
The green roof itself has a fleece at the bottom then a drainage layer of aerated clay pebbles before the soil, here to about 125mm depth but the sheds are pretty tough so this could be bigger if required. The sleepers look really good but an alternative would be cobbles in gabion cages depending on what would fit with your front garden. Order page.
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.
Not all my green roofs are in London, you can see one of my early ones in Welwyn Garden City and this magnificent roof on a garage in Spring Gardens in Marlow
The roof was installed early this year using Shire substrates and materials from Optigreen. I used expanded clay for the drainage layer and large cobbles to create a more natural looking border.
The roof had loads of really nice seeds in it and was also planted with some sedums, aliums and stipa grasses and it has really blossomed tremendously.
