Foreman’s House At The Bosbaan (gesloopt)

The Bosbaan, or Woods Course, is the oldest manmade rowing lake in the world. It was built in the Amsterdamse Bos in 1936, and it was expanded in 1954.
Which gives a couple of interesting date possibilities for this awesome opzichtershuisje, or foreman’s house. The simple, clapboard and wood frame construction makes me think it’s the latter, though, a post-war modernist bonus. Here’s a Google Map view of it.
Do you see that floating staircase on the front corner there? Do you wonder if Winy Maas saw it at some point, too?
Unfortunately, “gesloopt” is Dutch for “demolished.”
