EIFS and Stucco Repairs
The 1120 North Lake Shore Drive building is an 18-story residential building located at the southwest corner of North Lake Shore Drive and East Elm Street. A private courtyard located on the south side of the building and hidden by the adjacent property provides space for an outdoor recreational area. The building was originally constructed of steel columns and beams encased in concrete in the early 1920’s. The building is primarily clad in brick masonry with decorative limestone pieces utilized as accent elements. The roof is comprised of a steep-pitched copper roof.
The scope of the Courtyard Repairs addressed deficiencies in the exterior concrete slab at the private courtyard to mitigate water infiltration into the basement areas below. Storage rooms in the basement were combined and converted into a common workout gym facility for the building residents. The bike shed in the courtyard was re-clad in EIFS to emulate the exterior appearance of the residential building.
