Recently completed, Caja Madrid is 820 foot tall, 900,000 sf office tower with a
5-level, 400,000 square foot underground parking garage. Caja Madrid’s distinct form,
two external cores bracketing a central office floor plate and supporting the entire
weight of the tower, evolved in a collaborative design process – bearing in mind
the principles of efficient tall building structural design. Structural design in
conjunction with Halvorson and Partners of Chicago.
