The owners of The Brass Alley and Evolution want to add a third floor to the building on Old World Third so they can have space for events and an outdoor patio.
Susan and Scott Mayer, who co-won the building with Wild Planet Hospitality, will ask the Milwaukee Historic Preservation Commission Monday to approve the expansion, which includes removing the existing roof that was built in 2008 when the bar was Bootleggers.
Wild Planet also owns Red Rock Saloon, McGillycuddy’s, Red Lion Pub, Trocadero and Three Lions Pub, all in the downtown Milwaukee area.
The Mayers opened a New Orleans-themed bar and restaurant called The Brass Alley, 1023 Old World Third on the first floor of the two-story building on Oct. 1. On the second floor is  Evolution Gastro Pong, which is the former Spin ping-pong facility at 233 E. Chicago St. in the Third Ward.
The third floor will feature about 3,500-square feet of glass-enclosed space where weddings and other private events can be held and a 1,500-square-foot outdoor patio, said Susan Mayer.
A contractor has not been chosen for the project; however Kelly Construction and Design, Milwaukee, did the work on the first two floors when the Mayers purchased the building and converted it from the Irish Rec Room and will likely be used again, Susan Mayer said.
The Mayers are hoping to have the third floor open by summer 2016.
The Old World Third building was constructed as a four-story structure in 1894 for Enno Dorestan & Son. The company supplied builders and contractors and remained on the premises until 1911. In 1952, a fire damaged the building and the upper two floors were removed.
