Forest For The Mies: A. James Speyer’s Adirondack Mystery Cabin

Have you seen me?
I’m fascinated by this house, though I can’t figure out if it ever even existed. It’s a “mountain week-end house” in the Adirondacks made with “tree trunk posts, slab sides, native stone, and 75% of walls glass.” Its architect, A. James Speyer, was at the time Mies van der Rohe’s first graduate student. Which makes the house sound like the strangely beautiful product of a one-night stand between the Barcelona Pavilion and a log cabin.
The house, like the Museum of Modern Art Guide to Modern Architecture: Northeast States it was published in, are both dated 1940, which could explain why there was only a drawing, not a photograph, available.
And yet I can’t find any mention anywhere of the house or its client/owner, one “Miss ‘Bird’ Sunstein.” Normally, I’d say that’s a sure sign the house was never built, but the guidebook contains detailed directions for visiting it. It’s several miles outside Warrensburg, NY, in the direction of the southwestern shore of Friends Lake. [Though they’ve upgraded some of the Earth Art locations recently, the Google Maps around Warrensburg are still unhelpfully low-res.]
Speyer would have been around 27 years old when the house was built. There are records of his architecture practice from as early as 1946, but his archives make no mention of any pre-war activities. [Speyer taught for many years at IIT, the Illinois Institute of Technology that was Mies’s American base. But he is probably best remembered as the longtime modern and contemporary curator at the Art Institute of Chicago. He passed away in 1986.]
In the last few weeks, I’ve cold-called a few promising-sounding Sunsteins and Speyers, hoping they’re related–and waiting to finally be asked to share their childhood tales of summers at Aunt Bird’s rustic modernist masterpiece. But so far, none of it rings the slightest bell.
Next up: contact the archivists at the Art Institute to see if there’s anything that may have fallen through the digitized cracks. Also, post about it online and hope that “Bird” Sunstein’s relatives are Googling during the holidays.
