Look, up in the sky!
It’s a bird!
It’s a plane!
It’s a… garden?
Yes, believe it or not, people have started creating gardens on the roofs aka green roofs.
So what’s this actually about?
Have some folks just decided to plant a few trees on a building roof out of fun?
Surely there is a bigger story behind all that… and we’re here to tell it.
“One of the most interesting global
sustainability trends is the appearance
of so-called green roofs, aka gardens
in the sky and by the looks of it,
the trend will continue growing
in a large scale.”
Here you can get a proper insight in the complete concept of green roofs, of their advantages,
popularity, but also their sudden appearance all over the world.

Of course, the idea might seem simple and perhaps silly, but its background is actually quite

Underneath this thriving vegetation exists a growing medium, followed by a filter membrane and
a drainage system, accompanied by a waterproof and repellent layer, a support panel and thermal
After all these cleverly thought out tiers, there comes a vapour control layer and finally the structural
While the idea might strike you as odd, soon you’ll find out that there is a perfect logically reason
behind this comprehensive project.
How It Started?
There are quite a number of speculations of where the trend has originated.
This is mostly because the concept of green roofs has been present for quite some time, but the
advanced urban architecture projects have appeared quite recently.
A few centuries ago the first signs of green roofs appeared in northern Scandinavia, except they were
called sod roofs and were used to hold the birch bark (a water-tight element of the roof) in place.
Modern green roofs, on the other hand, have appeared in the 60s in Germany, as a way of energy
Since then, many European countries have embraced the trend, but Germany still remains in the lead,
with estimated 10% of all German roofs becoming green.
