Real estate deals seem to happen with all the ease of money being passed across a Monopoly board in this city. And even then, there's not enough office space to house everyone who wants a downtown office: People still run start-ups out of apartment buildings, or work exclusively in crowded cafes. The best anodyne to this problem is shared workspace, and the best example is Impact Hub, a suite of nonprofit offices, education centers, and art galleries, all clustered together inside the Chronicle Building. Its founders believe the sharing economy can apply to all forms of urban development, and that open floor plans are the first step toward a more flexible, collaborative society. It all starts when we set our laptops down on the same table, and sit down in the same ergonomically correct chairs.
