St. John Properties has begun construction of three buildings that will add more than 135,000 square feet of space to its 413-acre Government and Technology Enterprise (The GATE) business community in the Aberdeen Proving Ground in Harford County.
The buildings include one single-story office building and "flex" buildings designed for office use or research and development activity. Scheduled for completion this summer, the three buildings are the last structures in the 350,000-square-foot, six-building first phase of The GATE. Construction of a second phase is expected to begin in May.
