Additional interior renderings and a new website have been revealed for the ongoing redevelopment
of the Thompson Center at 100 West Randolph Street in The Loop. The iconic structure dates back
to 1985 but had long been plagued by maintenance issues, until a group of local developers partnered
with Google to remodel and reposition the property.

Led by The Prime Group and Capri Investments, the 17-story structure was stripped down to its frame
in order to provide blank Class A office space designed by JAHN. As of earlier this year, the exterior
has also been largely re-clad in energy-efficient glass. This, coupled with a new smart HVAC system,
will address many of the building’s previous shortcomings.

Recently, Google also received a permit to begin interior renovations across the lower nine stories. Local
firm Partners by Design has been working on the $85 million plans, which call for a new office lobby,
central kitchen, bike storage, food hall, restaurant, conference spaces, lab space, and general office
space within Google’s footprint.

This leaves the upper floors of the structure available for additional office tenants, along with retail
space along the lower levels and within the interior atrium. The new website highlights curated retail
mixed with food and beverage options open to the public and connected to transit. For office tenants,
it touts floor-to-ceiling glass, nine-foot ceilings, long column spans, and integrated technology.

The development team has brought on CBRE to lease the majority of the six upper floors of office space,
while the State of Illinois will retain a small amount of space within the building. The retail space is being
leased by Savills. The over-$250 million project is on schedule for completion later this year, with Google
expected to move in soon after.
