The Northern Tier is bounded by 1–70 on the north, Pearl Street on the east, Sycamore on the south and Short Street on the west. This tier is close to the Scioto River and has much of the district's earliest development. It is characterized by its remaining historic, industrial buildings featuring much brick and having very little to no setback. Some industry still remains in this tier, but the area has experienced large-scale re-development. The Germania Singing and Sport Society building, the former Schlee Mansion, is the oldest building on Front Street. This building, at 543 S. Front Street, (photo to the right) and its carriage house both appear in a 1870 city plat. The Schlee Brewery was recently adapted for mixed-use, including some residential units and specialty commercial spaces. This Schlee Brewery project and others have set the tone for this tier's re-development. In July 2019, it was announced that the L. Hoster Brewing Company site (including the former Wasserstrom Building) at Front Street and Livingston Avenue would have a $70 million redevelopment. The Hoster site is proposed to include a hotel and restaurant.
