Mixed-use developments (MXDs) combine several uses into one complex, including shopping centers, office towers, hotels, residential complexes, civic centers, and convention centers. They are pedestrian-oriented and therefore facilitate a live-work-play environment. They appeal to people who have had enough of long commutes to work and look for a lifestyle with more time for the things they enjoy. Retailers like MXDs because they bring additional shoppers to their stores. They are also popular with governments, urban planners, developers, and environmentalists because they provide a pleasant, pedestrian environment and are an efficient use of space.
