After he was booted from his white-on-white-on-white loft when the Bozza Mansion was torn down, John Cage kind of drifted for a while. Apparently it was hard to find a good deal on a great space in Manhattan in 1954 [when you had no money.]
So for a while, Cage moved to The Land, one of the names for the pseudo-commune/art colony started by Paul & Vera Williams on 116 acres in Stony Point, Rockland County, NY. Paul was an architect friend of Cage's from Black Mountain College, and he'd purchased the property after inheriting some money.
I don't know why, but I'd always assumed Cage and the other The Land folks lived in little cottages. Not quite. It turns out Williams, a student of Breuer, created some classically modernist boxes.
The first pictures I've ever seen are in Brendan W. Joseph's 2016 book, Experimentations: John Cage in Music, Art, and Architecture, which goes into some detail on the development of The Land and its surprising impact on Cage and his work.
Cage shared a building, a duplex, with the Williamses. He lived in 1 or 2 rooms on the left in the image above, separated by a stone wall he and Vera built. It looks quite nice, if simple, a bit like the Black Mountain College buildings everyone built together. Indeed, from Joseph's account, it sounds like Williams was hoping to recapture some of that BMC mojo with his co-op experiment.
