The developer revamping the former Texas Instruments office campus in Plano has unveiled plans to add new retail and restaurant space and a hotel north of Legacy Drive.

On Feb. 17, the Plano Planning and Zoning Commission approved the revised preliminary site plan requested by Los Angeles-based Regent Properties, which is redeveloping the property under the name Legacy Central.

The new plans depict a four-story, 90-room hotel west of U.S. 75. They also show a longer, L-shaped building that designates 50,000 square feet of space for restaurants and retail stores on the property’s west side.

The two additions would join a flurry of development activity that has occurred in recent years south of Legacy Drive. As part of the Legacy Central project, crews have replaced the parking lots and fields that used to surround the office buildings with apartments, restaurants, retail stores and green space.

Regent Properties did not immediately reply to a request for comment.
