I've posted before about Madderlake, a pair who made their name in flowers back in the 70's. Madderlake has since transformed into a landscape and architecture firm. I find their portfolio to be quite lovely with my favorite being the apartment of Joel Grey. They transformed a narrow, dark apartment in Manhattan into a series of English conservatories filled with gorgeous light, art, books, and just-plucked-from-the-garden flowers!
