An indoor climbing gym is the first tenant named for Union Collective, the Medfield warehouse that Union Craft Brewing is converting to a space for its brewery and other businesses.

Earth Treks Climbing and Fitness will open a 20,000-square-foot gym at Union Collective in 2018.

Union Craft Brewing announced plans this month to buy the 10.5-acre site, a former Sears warehouse most recently occupied by plastics-maker Hedwin, which relocated to Delaware. The company is working with Seawall Development to renovate the 138,000-square-foot building at 1700 W. 41st Street into a space that will accommodate a larger brewery and taproom as well as manufacturing and retail space for eight other organizations.

“Our goal in developing Union Collective is to do our part to make our city a better place to live, work and play in,” said Adam Benesch, co-founder of Union Craft, in a statement. “A key aspect of that mission is to retain existing growing businesses already in Baltimore, as well as attract new ones to move to the city for future growth.”

With more than 10,000 square feet of bouldering terrain, the climbing gym will be Earth Treks’ first focused on bouldering, a form of rock climbing without ropes and harnesses.

The gym also will include a yoga studio, designated areas for fitness, cardio and training, and a pro shop.

The gym will be Earth Treks’ first in Baltimore. The company has five climbing facilities in Maryland, Virginia and Colorado. Its three Maryland gyms are in Columbia, Timonium and Rockville.

“Earth Treks has served Baltimore-area climbers since 1990 and we are thrilled that at long last we’ll be opening our first gym in the city,” said Chris Warner, Earth Treks founder and CEO, in a statement. “There are many synergies between the climbing community and craft beer community, which made this development and partnership the perfect fit for us.”
