Favorite material to work with: “Space, and organic matter: soil, wood, stone, etc. They’re materials that inspire us just by looking at them.” Pictured: A portion of Here There - There Here installation, created this summer with L.A.'s Welcomeprojects as part of Andrea Zittel's High Desert Test Sites outside Joshua Tree, which Olson says was a nice conceptual middle ground between ROLU's landscape and design work. “We also love steel, and traveling to the steel yard. We have two huge residential landscape projects happening this summer that involve steel, and we’ll use it extensively during our residency at the Walker Art Center this summer. It seems like it’s only a matter of time before it works its way into other areas of our creative practice.”
