Continuing Collaboration

Microsoft, World Headquarters

Callison has partnered with Microsoft since 1985 to plan and design countless office buildings within their world headquarters campus as well as data facilities across the U.S. and Europe. Completing almost 6.75 million square feet of space worldwide, Callison provides comprehensive services including master planning, building design and workplace interiors. Although our approach and delivery has evolved over the years, we have been consistently successful in achieving Microsoft’s goals: reflecting their understated corporate image, providing flexibility for growth, supporting employee productivity and preserving the natural beauty of their campus.
