Super Junior member and actor Choi Siwon has earned an impressive profit through a smart real estate investment.

According to a report by News1 on April 27, citing Building Road Real Estate Brokerage, Choi Siwon purchased a two-story standalone house near Apgujeong Rodeo Street in Sinsa-dong, Gangnam-gu, Seoul back in September 2015 for 1.1 billion KRW under his personal name. He later demolished the original house and invested several hundred million KRW to build a new three-story commercial building, now home to a pub, café, and office spaces.

As of 2025, the market value of Choi Siwon’s building is estimated at around 5.4 billion KRW. Considering the total acquisition and construction costs of approximately 1.4 billion KRW, he is projected to have made a profit of about 4 billion KRW over the past decade.

A representative from Building Road Real Estate told News1, “From March to November last year, properties in the vicinity were sold at prices ranging from 2.12 billion to 3 billion KRW per pyeong (3.3㎡). Based on the building’s age, location, and road conditions, the estimated price per pyeong for Choi Siwon’s building is about 2 billion KRW. When multiplied by the land size of 27 pyeong, the estimated value reaches approximately 5.4 billion KRW.”

Meanwhile, Choi Siwon’s subunit SUPER JUNIOR-L.S.S. recently dropped their new Japanese single PON PON on April 18. He is also actively engaging with fans through the Channel A variety show Heart Pairing and his latest movie Lobby, which premiered on April 2.
