Architecture has always shared a blurred line with art. Perhaps it's not as pure of an art form as sculpture, but in addition to functioning as an occupiable space, it still needs to inspire and make an emotional impact. The difference between art and architecture is usually thought to be one of context and motivation; the artist is unconstrained and free, the architect caged by function. But in practice is it as simple? Artists think architecture is much more difficult because there is less freedom, but perhaps it is just different because it has a functional starting point. In architecture the trajectory of a spatial idea may be kick-started by an interpretation of function. In all, creativity constraints must be translated into opportunities.
