In the wake of the sub-prime mortgage meltdown, global warming, rising energy costs, and constant gridlock, you’d think the model of Suburbia isn’t faring to well. Well, you’re not alone. Dwell and Inhabitat are sponsoring a competition called Reburbia, dedicated to re-envisioning the suburbs. They’re asking entrants to design “future-proof” spaces, from small scale retrofits to large-scale restorations, to replace current types and systems like McMansions, cul-de sacs, big box stores, strip malls and car-centric communities. Ideas, they suggest, could come in the form of bicycle transportation hubs, energy generating freeway paving systems, and new housing prototypes (including a “McMansion farm rehab”, whatever that is). Enter here. And hurry, because entries are due on August 1! Winners will be announced on August 19 (Grand prize: $1,000).
