Sierra Towers is a residential 31-story high-rise condominium building in West Hollywood, California, United States. located at 9255 Doheny Road, adjacent to Beverly Hills. It was designed by Beverly Hills mid-century modern architect Jack A. Charney, who studied under Richard Neutra and Rudolph Schindler. Completed in 1965 as an apartment building, it was originally called the Spoon Apartment Building.

Construction

Sierra Towers was developed in 1965 for US$12million (equivalent to $million in ) by Walter and Leo Minskoff, whose family firm also built New York's Minskoff Theatre. The building is known for being more than 15 stories taller than any other building within a 2 mi radius. Due to Sierra Towers' unique positioning at the base of a hill (the same hill from which Beverly Hills gets its name), the building is the highest residential tower in the greater Los Angeles Area relative to sea level. The building is said to get its plural name from scuttled original plans to build a second tower.

Notable residents

Sierra Towers was first operated as a rental property, but following its purchase by New York real estate investor Helmsley Spear Inc., the building was converted to condominiums in 1974. A number of celebrities own condominiums in the 146-unit building, including Karyn White, Diahann Carroll, Sandra Bullock, Kelly Osbourne, Robert Sherman, Jim Morris, Brody Jenner, Emma Watson, and Meg Whitman (since 2018). Historically, residents and owners have included: Joan Collins (25th floor, –2017); Lily Collins (–2019); PJ Harvey (29th floor, 2003–2018); Matthew Perry (–2011); and Lindsay Lohan (2006–2007). In 2013, singer-actress Cher sold her 2302 sqft two-story condominium, created by combining two one-bedroom units on the 26th and 27th floors, for US$5.25million (equivalent to $million in ). In early 2014, Sandra Bullock purchased a 1672 sqft unit in the southeast corner of the building's 22nd floor for $3.35million (equivalent to $million in ); in 2017, she bought a second, 2101 sqft unit on the 20th floor, for $5.13million (equivalent to $million in ), while placing her original unit on the rental market at the same time, at $22,000 per month (equivalent to $ per month in ). Joan Collins's former 2300 sqft residence, on the 25th floor, was sold in 2017 for $4.4million (equivalent to $million in ). In 2020, Courteney Cox sold her 1315 sqft unit on the same floor for $2.9million (equivalent to $million in ). The Wall Street Journal reported that Evan Metropoulos, a principal at his family's investment firm Metropoulos & Co., has bought and sold multiple units in the building. He purchased a unit in 2014 for $3.5million (equivalent to $million in ), selling it in 2016 for $4.65million (equivalent to $million in ). He bought two units, to be used as staff quarters, plus two penthouse units, over the course of 2012 to 2015, including expenditures of $30million (equivalent to $million in ) to buy and combine the two penthouse units into one unit totalling 7000 sqft. By 2018, walls had been removed to create the single penthouse unit, but renovations were still incomplete, so Metropoulos – who had, while waiting, purchased a Beverly Hills mansion – listed all his Sierra Towers units for sale at a combined price of $58million (equivalent to $million in ); the listing was reduced to $33.5million (equivalent to $million in ) by 2021, when Metropoulos decided to sell the properties by auction, with no reserve price. In 2023, Katy Perry purchased a penthouse apartment for $11million (equivalent to $million in ).
