Most often, this job is performed by the fronts of buildings which, if adequately porous and deep, attract both walkers and lingerers. By porous, I refer to windows and doors, proper interior lighting, and any other measure that better connects the interior of the store to the sidewalk. By deep, I mean the degree to which the facade provides opportunities for shelter, leaning, sitting, and other physical engagement, and also how effective the design is at blurring the distinction between public and private while drawing out the experience of entering and exiting.
