In the early 1900s, the Chelsea Building stood as one of Los Angeles' most resplendent hotels, epitomizing elegance and architectural prowess. The name "Chelsea" was derived from its esteemed proprietor, Harry Alexander, adding a personal touch to the structure's storied history. The building was conceived in 1905 as an exquisite addition to the already iconic Alexandria Hotel. The brilliant mind behind its design was none other than John B. Parkinson of Parkinson & Bergstrom, a duo revered for their architectural genius in that era. The realization of the Chelsea Building's blueprints was championed by two visionary developers of their time, Albert Bilicke (1861–1915) and Robert Arnold Rowan (1875–1918). Together, they contributed to crafting a landmark that would forever remain an indelible part of Los Angeles' architectural tapestry. In 2012, the City of Los Angeles deemed the Chelsea as a Historic-Cultural Monument.
