Architecture is both private and public. The simplest enclosure, a room, has its private inside realm, and beyond that an exterior that is on show to the world. We should create buildings and define spaces that respect and engage with all users, passers-by, and the wider environment. Architecture is also infinitely varied; each project is unique, responding to the local conditions. Buildings should last longer than fashion; a timeless and elegant design will outlast changes in fashion. And yet each new building later always shows its period; our designs should be of their time, and when we design for the conditions needs and merits of our own time, they will be.
