Name of an architectural/urban design project ?

I can't bear in mind the identify of a mission that i noticed some time in the past, i attempted to do a sketch of what i bear in mind. The large supposed use was as benches.

What im pretty sure of : – it's a recent-ish mission, like submit 2010 – the form was fairly natural, as in my sketch – its foremost materials was wooden and perhaps metallic – it reused the supplies from some place else

What im much less sure of : – it was a short lived mission – it was in europe – unsure if it was in a number of concentrated circles or if it was only one and one thing was hapenning within the middle

So yeah idk if that is even the best sub but when anybody has any thought I'd respect it !
