A developer has submitted site plans to the city of Wilmington that, if approved, would add a fourth building to Mayfaire's office park. 

The proposed 40,500-square-foot, three-story building at 6761 Rock Spring Road behind Mayfaire Community Center would add more class-A office space to a corridor where it has been in high demand recently.

The site plans for The Offices at Mayfaire IV were completed by Tripp Engineering of Wilmington.

Developer Steve Anderson developed the first three phases of the Offices at Mayfaire. Signs of Anderson's along Military Cutoff Road have long advertised the coming of a fifth and sixth phase for the office development, in addition to The Offices at Mayfaire IV.

Anderson is also working on a 20,000-square-foot office building near the corner of Military Cutoff Road and Wrightsville Avenue, currently under construction by McKinley Building Corp., where announced tenants are expected to include Glo MedSpa and Paul Vision Institute.

In June last year, Tennessee-based CBL & Associates bought the retail components of the Mayfaire mixed-use development, Mayfaire Town Center and Mayfaire Community Center, for $192 million before selling Mayfaire Community Center in December. Those sales did not affect the office portions.
