This is Peter Zumthor's studio in the small village of Haldenstein, just outside of Chur in the Graubunden region of Switzerland. The first studio was built in 1986, with the concrete extension - adjacent to his private family home - added in 2005.
The area is not fenced off, but your attention is drawn to a small plaque near the door of the concrete atelier extension which reminds people that this is Peter Zumthor's family home and to respect his privacy.
How to get there?
Park in the centre of Haldenstein and wander up north, you will pass the Zumthor atelier.
