01

Canonical identity

This Public Seed maps the office-building identity while keeping the project park, riverwalk, railroad infrastructure, air rights, parcels, title entities and tenants separate. Public contacts are currentness-limited and do not establish access or work authority.

02

Area claims stay separate

Gross, rentable, and office area are not interchangeable. Factum stores each measurement with its source meaning instead of choosing a convenient single number.

03

What public guidance supports

These are sourced research answers, not permission to enter, reserve, submit, or dispatch. Current affected-party authorization remains required.

Project boundary

First-party sources describe a landscaped park and riverwalk frontage within the project, but Factum does not infer shared title, parcel or operating identity.

Questions this record answers

Each concise answer includes the same caveats shown elsewhere on the page.

01What is 150 North Riverside Plaza?+

It is a 54-story office building at 150 N Riverside Plaza in Chicago; the official site says it was built in 2017 and contains 1,226,111 square feet of leasable office space.

02Are the park, riverwalk and railroad property part of the same building record?+

Only their project relationship is recorded. Factum does not merge those components, air rights or parcels into the building identity without authoritative evidence.

No. Current authorization, access, dock, freight, safety, emergency and telecom-riser procedures were not established.

04How can I correct or enrich this record?+
