When Suburban Bank and Trust (SBT), headquartered in Elmhurst, IL, bought a small building for a new branch location the primary challenge was to give it an identity more fitting with the SBT style. The structure was built in the 1970s and needed more than just a new face so the bank called on PPKS Architects, Glen Ellyn, IL for help. The design from PPKS features 1,400 square feet of Kalzip TF37/800R façade system made of 0.040 aluminum with a twin-triangular profile that creates an interesting exterior through an interplay of light and shade across its shape.
