You must be thinking of old Truck Co. 11's house...on the southside of North Avenue between the Jones Falls Expressway and Mt. Royal Ave. 11 Truck was formed in 1898 in E-18's house. That house was built about 1920 (North Avenue was the City Line until 1919). High Pressure Service Hose 3 moved in in 1921. A new Engine 1 (formerly the Rescue Company) moved in late 60's-early 70's. I visited that house in 1974. At that time there was a vacant lot on the west side of quarters. Up until Sunday, March 2, 1930 it was a three story auto supply warehouse. Although it was 15 degrees outside, it was noticed that the firehouse was getting warmer. Then someone found the west wall hot to the touch. The Home Box No. 353 went to six alarms, a cupola on the roof fell onto Engine 28's pumper set-up on a nearby hydrant, and bunch of guys got frostbite.
Now it's just another vacant building in a city full of vacant buildings.
