Brooklandville is an unincorporated community in Baltimore County, Maryland, United States near where the Jones Falls Expressway meets the Baltimore Beltway. The general area is a part of Lutherville, and some addresses in the area are considered to be in Lutherville, though Brooklandville has a postal zone and post office of its own. Some notable landmarks in the area, including the Park School of Baltimore and St. Paul's Schools are technically within Brooklandville, as noted by their mailing addresses. However, addresses within the main office complex in the area, Green Spring Station, are considered to be within Lutherville. The Green Spring Station complex is located at the intersection of Falls and Joppa Roads, near the interchange of I-695 and the Jones Falls Expressway, and is also bordered by Greenspring Valley Road, though the segment of this road that runs through the complex is identified as Station Drive. Seminary Avenue also begins very close to the location. The complex has offices for several large companies, as well as some upscale shops, restaurants, banks, and the largest indoor tennis facility in the Mid-Atlantic. The most notable company with offices at Green Spring Station is Johns Hopkins Hospital, which has a satellite branch that takes up a large portion of the grounds, and has been operating this location since 1994.
