"In the dining nook adjacent to the kitchen, there is a Bocci 21 light and a vintage table. I love thinking about how these things will travel with us for many years, like companions. Aileen and I have a strong relationship to objects: They are a tactile diary of our lives. The interesting thing about our home is not the structure itself, but the way it has become an intimate part of us. The most sustainable thing we can do as architects and designers is to make spaces and objects worthy of a lifetime commitment. Then [the objects] can have five, six, ten lives instead of half a life."
