what's this designer's name?!

It’s been driving me nuts. Does anyone know the name of the designer or the artist who does the installation pieces similar to the Campana brothers’ Favela Wall and Favela Chair?

I remember he was commissioned to do a few cave-like entrance structures for events at design festivals a few years back. They were made of randomly oriented boards nailed together. I think for one of them, all the boards were painted blue.
