‘Spectacular’ green roof in Dulwich

I built this one last week on a garden office in Dulwich. I don’t do so many sedum roofs but this did come up looking really nice and is instantly green.

The roof build up was using the Optigreen lightweight roof system. A protection fleece over the waterproofing, drainage layer, lightweight substrate and pregrown sedum on top. This was ideal for this garden office and really helped it blend in to the trees and plants at the bottom of the garden. The roof will drain into a gutter when complete (not that there will be a lot of runoff). I used aluminium edge trim all the way round to give it a nice defined edge.

The substrate was incredibly dry when it arrived, I initially thought it was just sand! This made it really easy to get up on to the roof, the bags weighed even less than usual. Luckily it has had a good soaking with the rain since to get it nice and wet.

Getting the sedum up on the roof was a little trickier, we left it out overnight and the client enthuisiastically watered it making it very heavy. After struggling with a couple of rolls I realised it was better to cut the mats in half to make them easier to handle.

Once it was all up it looked really good. I spoke to the client again the week after to check on it and he said ‘It looks absolutely stunning. The wife and my nearest neighbours really like it – so a big thankyou. I have been diligently watering it and it is looking good. Many thanks‘ very pleased with the feedback.

Lockdown green roof

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.

Muswell hill roof

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.

SYdenham hill green roof

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.

East dulwich green roof

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.

Hackney retrofit green roof

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.

Highgate green roof

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.

Stoke Newington roof

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.

Green roof on a bike shed

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.

Still flowering in March

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.

Freshly planted

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.
