Originally constructed in 1986 as a headquarters building for Southwestern Bell Corporation and now AT&T, 909 Chestnut is truly one of the major landmarks in the heart of downtown St. Louis. As one of Missouri’s largest buildings at 1.2 million square feet, 909 Chestnut soars 42 stories providing dramatic panoramic views. Now, nearly 30 years after it was originally constructed, 909 Chestnut is undergoing an exciting transformation with dramatic planned renovations – transforming it into a state-of-the-art office tower with the potential for new restaurants, shops, meeting rooms, fitness, inviting common areas, dramatic new lobby and signage opportunities for anchor tenants. Future top-to-bottom renovations will reimagine and redefine 909 Chestnut, creating a dynamic, unique and energizing work environment for a thriving business community.


Luxury Redefined

The building will provide tenants with a full range of on-site amenities and easy access to the vibrant downtown St. Louis community.  Updates include a modernized, luxurious and inviting lobby, the addition of conference rooms and an on-site café.

Renovations Include:

  • Updated, modern lobby
  • Newly constructed outdoor area
  • Sustainability features
  • Newly appointed conference center
  • Optimized square footage to create flexible tenant floor plans
  • Reconfigured entrances/exits for improved traffic flow
  • Updated exterior lighting to make the building more prominent in the St. Louis Skyline
