Engine Company No. 1 was located at 344 Boulevard of the Allies in downtown Pittsburgh, Pennsylvania, and Engine Company No. 30 is located directly behind it, on the other side of the building, at 341 First Avenue. Built around 1900, architect William Y. Brady, the Boulevard of the Allies facade is Beaux Arts and Classical in design, and the First Avenue facade mixes Romanesque and Classical styles. Both were added to the List of City of Pittsburgh historic designations (together, as a single listing) on March 17, 1993.
In 2011 the city sold the closed station to Point Park University.
