Based on retail floor space, Southlands is the largest non-enclosed mall in the United States.

It opened in 2005, featuring a unique design incorporating a "Main Street" of shops and smaller eateries, surrounded by larger stores near the perimeter of the center.

Southlands Lifestyle Center utilizes an open-aired, Mainstreet style central shopping area which is ideally suited for Colorado's moderate climate.

The street is adorned with hanging plants and planter boxes and angled parking spaces on both sides.
