Tower Bridge Office and Hotel Complex

 


A series of additions over a period of years has transformed the original modest headquarters of this rapidly growing, privately held company into an impressive, bustling corporate campus.  A data processing/executive office wing, which forms the “front door” of the campus, was followed by renovations of existing office space and additional wings housing offices, computer operations, and food service facilities.  New construction has completely surrounded the original buildings.  A conference/training center was added as a freestanding building in the interior of the site. The total complex now comprises approximately 150,000 SF

The various parts of the complex are unified by a consistent vocabulary of punched windows, brick with cast stone trim, and hipped, shingled roofs.  The traditional look of the buildings carried throughout the interiors recalls no specific earlier stylistic source, but reinterprets traditional forms and construction with a contemporary flair resulting in an appealingly timeless character.  This is accentuated by the broad and beautifully landscaped lawns that surround the facility, creating a commanding presence to the adjacent commuter highway.
