A tiresome question in architecture is whether unbuilt projects have a greater value than real buildings. Generally, a complete realization of architectural service is necessary to pay the bills. Hadid persisted as an artist before getting shovels in the ground. Her dramatic career cut short lends an air of drama to her unfinished designs and entertains the speculation of how feasible her more uncanny visions will be--provided a client with deep enough pockets.. Her firm persists, which makes us wonder how derivative they will be, and how long they will last. Frank Lloyd Wright's studio produced nothing of significance after his death.
