How would you transform a public space in your city to make it more comfortable? The BMW Guggenheim Lab, freshly installed in Berlin (the second stop on the project’s six-year global tour), wants to know. The joint initiative of the Solomon R. Guggenheim Foundation and the BMW Group has partnered with the “reasonable people who give a damn” at GOOD to launch a worldwide, online call for forward-thinking, imaginative, and downright wacky (OK, “unconventional”) ideas to improve urban comfort. So put on your most aerodynamic, stylish, and sustainable thinking cap, grab a fresh Moleskine, and get to proposing—in three to five sentences—changes to public spaces in your corner of the world. Factors to consider: the community, environment, architecture, landscaping, and any other aspects that would affect the experience of the space. GOOD and BMW Guggenheim Lab curator Maria Nicanor will select their favorite ideas to be featured on the GOOD and BMW Guggenheim Lab websites (although we plan to hold out for a deal on a 3 Series Convertible). Submissions, which can include an image of a sketch or model that corresponds to the idea and shows how your idea would be implemented, will be accepted through Tuesday, July 17.
