Architects: Rogers Stirk Harbour + Partners
Location: Miami, USA
The Santander Headquarters Building in Miami, is a 77,000m² office skyscraper designed by Rogers Stirk Harbour + Partners. This project is one of two proposals, which demolishes an existing 14 story office building on the site. Due to Miami’s strong winds and high water table, buildings require very a specific structure and design. Lateral stiffness, strength and stability became the dominant consideration for the initial design resulting in a centre core structure, with a cruciform floor plan, tapering slightly toward the upper floors. The central concrete core is connected to eight perimeter mega-columns via several levels of outrigger trusses located at the plant floors which divide the office floors at 12-storey intervals. The symmetrical plan shape of the building provides lateral stiffness in two directions leading to a highly efficient stability system. Because of the cost implications of delivering below-grade parking in a high water table area, the lower 15 floors are given over to car-parking.
