From 1972-1981, the planning and development of the White Marsh Mall occurred, with the Rouse Company as owner and developer on land rented from Nottingham. In July 1973, Sears committed as an anchor store. In 1981, most stores opened. In 1992, Hecht's replaced Hutzler's. The White Marsh Mall is one of the largest regional malls in the Baltimore area, with five anchor stores and 190 specialty shops in about 1.4 million square feet (130,000 m²). Next to the mall's property is the third IKEA store built in the United States, the oldest still remaining.

In addition to the Mall, 2,400 residential units have been built in the town center and 700,000 square feet (65,000 m²) of office and research and development space have been built.

The White Marsh Library opened on January 25, 1988. It is part of the White Marsh Town Center, which includes the White Marsh Mall; the White Marsh Police Station, which opened in November 1987; the Nottingham Post Office, which opened in November 1990; and thousands of square feet of retail, industrial, and office space, which are still being developed. These are named "White Marsh" but are, in fact, in Nottingham and have the zip code 21236.
