Presidential Towers is a multi-tower residential apartment complex built in 1986. The podium of the tower complex houses multiple retail spaces within the whole city block. The southeast corner of the podium building was rehabilitated to attract new tenants to the key retail location

The redevelopment included adaptive reuse of the existing concrete-framed building with a new glass and steel corner vestibule. A monumental stair to a 2nd floor roof deck was included. Structural engineering services were provided including the structural design of the new steel framing, foundations, monumental stair and roof deck.

K&H provided structural design and construction administration services throughout the redevelopment project. Since the original corner of the building was partially demolished to allow for the new double-height entry vestibule, the design focused on re-supporting both the original concrete structure and new steel-framed vestibule. Design of the new monumental stair required aesthetic consideration for the architecturally-exposed steel framing. The roof deck was designed as a loose-laid structure, thus not required invasive demolition at the roof surface.
