Bavinger House. I remember watching an "Arena" about Bruce Goff on my little b/w tv when I was young, and really being moved by his organic designs. They just made me smile, like lovely domestic buildings should do.
Metropolitan Cathedral, Liverpool. This building really speaks to me. I love the way the heavy doors rumble open, and the whole design is so consistent. There is a real sense of spirituality, peace and enlightenment about the place.
