Though it is a cold, soggy field today, this lot near SMU could be a 20-story development with penthouses and efficiency and one- and two-bedroom apartments.

Zoning documents list Westdale Palomar L.L.C. as the property owner and Toll Brothers as the applicant for a zoning change. They hope to increase the density of the undeveloped, triangular lot from 150 to 218 units per acre and the floor space from 200,000 to 450,000 square feet. The application also requests that the residential development’s maximum height more than double from 133 to 285 feet. As a comparison, the Adolphus Hotel is 312-feet and 22-stories tall. Next to the lot, the Highland Hotel is nine-stories high.

The lot, which is at the southeast corner of Mockingbird and Central Expressway, sits between the Highland Hotel, the service road and a storage complex. It is adjacent to the University Crossing Trail, which now passes over Mockingbird Lane and connects the Katy Trail to Ridgewood Trail.
