Alright, alright, I'll admit it: I have a thing for open-planned homes made out of concrete, steel and glass. Something about them just speaks to the Modernist in me, I guess. And while my actual preference of places to live involves a lot more wood than steel, that doesn't mean that I can't still ogle architecture like the Brazilian querosene house, designed by groupoSP. The real draw of this home for me not just the interesting design, however. As usual, it's all about the books. An entire multi-storied library consisting of 7,500 books to be exact.
