Designed by architect Welton Becket, the building exemplified his penchant for repetitive geometric patterns and walls clad in natural stone. Landscape architect SWA Group's design for the busy triangular/flatiron site created an octagonal, two-tiered opening leading to the Montgomery Street Bay Area Rapid Transit station, and flanked by trees, shops and a series of granite steps used for seating.{{Cite web | title=Cultural Landscape Foundation |url=http://tclf.org/landscapes/one-post-plaza | publisher=TCLF.org| accessdate=2012-02-17}}

In the soap opera The Young and the Restless, the building is featured as "Lakeview Towers", where numerous characters — beginning in 2012 with Victor Newman — have lived in either of two adjoining penthouse apartments.{{Cite web|title='Young and the Restless' builds new home for Victor Newman|url=https://ew.com/article/2012/12/03/young-and-the-restless-victor-newman/|access-date=2021-08-16|website=EW.com|language=en}}
