While the store prototype is 10,000 square feet, stores slated to open generally range 10,000 to 17,000 square feet, significantly smaller than the typical U.S. supermarket, but also two to three times the size of the typical U.S. convenience store.lthough the look-and-feel of the stores are not significantly different, product assortment is reduced. In addition, the stores cost $5 million less to build, $1.5 million less to stock and require 25% less employees than the typical Lowe's; however, sales per square foot are about 84% of the typical store.
