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.
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.
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.
Lots of green roofs going in recently and I need to spend more time documenting them. This one in Marlow on a garage was a new design that I am quite pleased with.
I have been working for a while to reduce further the plastics going into a green roof. I used to work with SUDS (Sustainable Urban Drainage Systems) a lot in the past and one thing I always noticed was the number of pipe manufacturers trying to shoehorn more plastic into natural drainage systems. Roofs obviously need to be waterproof so I can’t change that bit and we need something to protect it from sharp objects etc. Then comes the drainage layer which is lots of plastic sheets, this is important to hold a bit of moisture but also to makes sure it drains effectively. So drainage is important for weight but maybe we can make it of something else. For this roof we used aerated clay balls wrapped in a filter sheet that is held in place with some extra large cobbles. So the plastic is at a minimum.
The cobbles add a really nice touch to the edge of the roof and enhance the appearance considerably especially on a roof like this where there is no parapet. The soil is also held in place by the cobbles and I guess some of it may wash between them but not off the edge of the roof.
The roof has been planted with about 15 different plants, some sedum and ornamental, seeded with 30 different wildflowers and also bulbs planted to come up later in the year. I am monitoring progress and plan to pick up some crocus bulbs in autumn to plant.

I went to visit an extension in Kennington which has the biggest domestic green roof I have built. There are some very big skylights so it isn’t all green but it looks great. This first picture shows the rear extension with some rather fine timber cladding, you can see the plants poking over the top of the coping stones:
The combination of rain and sunshine we have seen this summer has been really good for the plants, even if people haven’t been so happy. I missed the peak flowering of this roof but there were still plenty in bloom on Monday. The clients daughter has a bedroom window looking out onto the roof and has been enjoying the developing scene.
The skylights really bring light into the house and the kitchen looks even bigger than the space the extension added on. You can see some of the plants waving in the breeze around the sides when you are having dinner.
I went to see the roof I built in Kennington last month and took some photos I thought I would share. I wrote about this one last year showing the build up process to a green roof. I was particularly pleased that the insulation we put on as an added extra has made a real difference to the householders, the side return was previously a no-go area in the cold winter months but has now become habitable with the added warmth.
Anyway here are a few photos to illustrate how well the roof has been growing over the last nine months:
Overall I am delighted with the roof and the clients are really pleased too. The roof has already developed really well and should develop further over the next few years. The roof should reach maturity after three years but different plants will dominate in different years and seasons.

Just a quick photo update from a roof I made in March. This was put together with Optigreen substrate, drainage etc and seeds and plug plants from Boningale Nurseries. It is growing well with lots of plant growth for the first year.
Recent rain should really encourage growth.
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:
Just a quick update, we broke ground on a new extension last week. It’s mostly just digging at the moment but still exciting. I got to put up a sign outside the house:
The project will develop over the next few weeks. The walls incorporate high levels of insulation and will be made using reclaimed materials including a white glazed brick interior and re-used wood cladding.
I spent some time in @ going through the plans from Clements Design with Shaun the project manager on Wednesday, checking the build process and making sure we will avoid thermal bridges. The design looks sound and we are starting on the steel supports over the next few days.
The guys all look smart in the new Ecoalex hi vis vests and are looking for opportunities to save materials on site and re-use as much as they can in the build.
I recently finished the first green roof I have built for a while and thought you might like to see a few pictures. This one was on top of a bike shed in Stockwell and it’s looking pretty good. Took a bit more work than I expected, although small it has just as many corners as a bigger one so had as many fiddly bits to do. I worked it out after a while though and it looks really good.
The clients had a good supply of soil so we didn’t need to get any elsewhere, they also had a good idea of what they wanted to plant. We used a combination of herbs, grasses and other plants. They wanted to try as many plants as possible to see which ones would take to the roof, should be a good plan and I hope the roof will evolve over the next few years, it will be interesting to see which plants are most suited to the roof conditions.
The only disappointment so far is the photos I took with my new phone which are all washed out and bluey. It’s just down the road so I will see if I can get some better ones but here are a few for now. If you want one for your shed or extension get in touch.
