Chicago Architecture Biennial by two young architectural collaborations, each stressing their research-based exploration of alternative practices. Of particular interest to me is the project by David Neustein and Grace Mortlock, founders of Sydney-based otherothers.
The opening review by Curbed.com goes to the heart of the problem, even while it oversimplifies the project:
"Turns out, America isn't the only place with a glut of over-sized suburban homes. Australians actually have the largest average home size in the world, which may explain why it took an Australian practice, otherothers, to create such an elegant solution to extraneous space. By building a covered courtyard within the frame of the home, the house-within-a-house concept downsizes in an intelligent way, reducing costs while adding new types of outdoor space."
