This is near Mineral Lake, WA. Passed this while traveling this weekend. Any ideas what it is? I think it looks like a old auto repair shop possibly? It was boarded up well, I made no attempt to gain entry.

Looks kind of like a firehouse to me, especially from the first picture; the two side parts look like where garage doors would be.

It's Schrodinger's Bando 'till you get a good look inside

I would guess it was originally a school that was later converted into something else.
