Revised plans for two proposed office towers at The Shops at Legacy received city of Plano approval.

The Plano Planning and Zoning Commission on Monday approved a revised preliminary site plan for an 11-story office building and a 10-story office building east of the Dallas North Tollway in Plano.

The proposed office buildings, each offering more than 300,000 gross square feet of space, would be located generally southwest of the intersection of Ashmill Drive and Bishop Road in Plano.

Commissioners also signed off on plans for a Sam's Club building expansion near Spring Creek Parkway and K Avenue in east Plano's Oak Point area as well as a site plan for a proposed common area just north of the Liberty Mutual office project in progress at the city's burgeoning Legacy West development.
