I wasn't actually, but that Officehaus (Bauhaus-inspired rental office building in Vietnam) was...but when I looked at Google images of the Mondrian pictures, refreshed my memory, decided no, too busy, with the rectangles all on one piece with black line dividers.
Even that, I basically don't like artwork on the walls. Unless I could change it every so often.
On the other hand, though, one high-end dealer in Cape Town...(I'll post some pics sometime)...an old Victorian house, and a warehouse loft, lots of paintings - originals - some of which I do like, and some references to what some people call obscene art.
But what I've always liked about his places is the fabrics.
