The real estate story of the couple Ko So-young·Jang Dongkeon, long regarded as "top 1% asset" stars, is drawing attention once again.
Earlier, in 2021 the Mnet program TMI NEWS revealed "best 13 stars who chose homes of the top 1%," and the couple Ko So-young·Jang Dongkeon was named as the No. 1. At the time the program reported that they were living in one of the country's most expensive apartments, drawing attention.
Jang Dongkeon owns a five-story building in Hannam-dong, which is known to be worth about 13 billion won. Ko So-young also owns a Hannam-dong building in the 15 billion won range. In addition, a villa they built in Gapyeong, Gyeonggi Province was reported to be worth about 2.4 billion won and is a building that won the 22nd World Architecture Award.
The P apartment in Cheongdam-dong where the couple live is also an ultra-high-end residence with a view of the Han River. This apartment, which features ultra-luxury community facilities, a top-tier security system and private elevators for each household, once set the record for the highest price when a unit with an exclusive area of about 273.96 square meters traded for 11.5 billion won.
In January 2026, Ko So-young once again drew attention by casually mentioning the Hannam-dong building on her YouTube channel.
In the video released on the 23rd "It's fine to play alone or to date, kids, but I'm alone..," Ko So-young stopped when she spotted a building across the street while walking the Hannam-dong road. Looking at the building she drew attention by saying, "Our building is doing well," and then expressed affection, saying, "The design is so pretty. I think it's the prettiest on this street. It feels European." She was also shown smiling and saying, "Good boy, hello."
The building is known to have been purchased by Jang Dongkeon in June 2011 for about 12.6 billion won. At the time it was considered a higher price than previous transactions, but as real estate values in the Hannam-dong area later surged, it ultimately became "The Divine Move."
After the high-end residential complex Nine One Hannam moved in in 2019, surrounding prices and rents generally rose, and this building has again drawn attention. Current market estimates are around 30 billion won, and it is estimated that the value rose by more than 17 billion won about 14 years after purchase. Accordingly, the building is also mentioned as a successful real estate investment example representing Hannam-dong. The couple Ko So-young·Jang Dongkeon own a total of three buildings in Seoul, and their total asset value is estimated at more than 40 billion won.
Netizens who saw the video expressed keen interest, commenting, "They said top 1% and owners of buildings worth hundreds of billions, the class is different," "It's the first time I've seen a celebrity talk about buildings so naturally," "It's cute and honest rather than bragging," and "It makes me like them even more."
