Grigori Fateyev is a St. Petersburg native who studied theatre set design there, then came to the US to study architecture at Cooper Union. His AF architecture practice, based in Hillsdale, has been responsible for a succession of conceptually original and ambitious houses and commercial buildings in Columbia and Berkshire counties, with a refined sensitivity to how structures fit into landscape. He’s particularly good at windows, which tend to sprout throughout his inventions in unexpected places. He’s also an excellent watercolorist, in the mold of Steven Holl, and modelmaker. As modernist architects go—and there’s plenty of competition, even locally—he certainly knows what he’s doing and doing it well, including in Hudson on Willard Place.
