Olympic Park Foreon registration nears completion, poised to reshape Seoul housing data

Olympic Park Foreon in Gangdong-gu, Seoul — billed as the largest reconstruction project in Korean history — is on the verge of completing its ownership registration process. Once finalized, sale prices for the 12,000-unit complex, which have been excluded from major housing statistics, will begin to be reflected in key indexes. Market watchers expect the inclusion to move not only Gangdong-gu's apartment price indicators but Seoul's broader housing price benchmarks as well.

According to the reconstruction industry, the Dunchon Jugong Apartment Housing Reconstruction and Improvement Project Association, which carried out the Olympic Park Foreon project, filed for initial preservation registration on May 14. The association had completed the relocation public notice on March 25. Processing and digital entry of the preservation registration is currently proceeding unit by unit. "Ownership transfer registration for all units is expected to be completed by August," an association official said.

Preservation registration is the procedure that opens a property registry for a newly built multi-unit building for the first time. Associations typically file for an entire complex in a single batch, but for a development as large as Olympic Park Foreon, staggered processing and digital entry can create timing gaps between individual units. Only after a unit's preservation registration is complete can subsequent steps proceed — including ownership transfer registration for general pre-sale buyers, title consolidation for association members, and the establishment of collateral mortgages.

Once the process wraps up, Olympic Park Foreon's market prices will begin appearing in major benchmarks such as the KB real estate price index. The complex began accepting move-ins in November 2024, but incomplete preservation and ownership transfer registration made it difficult to track actual sale prices. Transactions conducted before registration carry the character of rights trades — such as association member move-in rights or pre-sale rights — rather than standard apartment sales. As a result, the complex's sale data has been absent from KB Real Estate's weekly and monthly housing statistics.

Olympic Park Foreon's sale trends are also not fully captured in the Korea Real Estate Board's weekly apartment market report. According to the board's website, its national housing price survey covers 217 survey regions drawn from apartments listed in the official price information database. Because Olympic Park Foreon has not yet been assigned an official assessed price, it does not qualify for inclusion in that survey.

Registration completion will change that. Once ownership transfer registration is finalized for individual units, those transactions will be classified as standard apartment sales rather than rights trades involving move-in rights or pre-sale rights.

According to the Ministry of Land, Infrastructure and Transport's actual transaction price disclosure system, the highest recorded sale price for an Olympic Park Foreon unit with an exclusive use area of 84 square meters was 3.3 billion won (about $2.38 million) for a 16th-floor unit, reported on Oct. 16 last year. Based on a supply area of 34 pyeong — where 1 pyeong equals 3.3 square meters — that works out to nearly 100 million won per pyeong, making it a premium property expected to weigh on Gangdong-gu's apartment price indicators. Last month, units of the same size traded between 2.75 billion won and 3.1 billion won, for units on the 26th and 34th floors respectively.

Once ownership transfer registration wraps up in the second half of the year, a wave of listings is also anticipated as general pre-sale buyers who moved in from November 2024 approach the end of their mandatory two-year owner-occupancy period.

Experts say the completion of Olympic Park Foreon's registration could reset the benchmark price for the new-build apartment market in the Gangdong area. "The share of transactions above 2 billion won in the Gangdong and Songpa-gu apartment market has grown sharply in recent months," said Kim Hyo-seon, a senior real estate specialist at KB Kookmin Bank. "Olympic Park Foreon is an ultra-large new-build complex that combines investment value with strong owner-occupancy appeal, so it is likely to serve as a benchmark for the Gangdong new-build market and pull up surrounding sale prices as well as jeonse and monthly rent levels across the board."

Meanwhile, another point of interest is how the KB Leading Apartments 50 index — which ranks the 50 complexes nationwide by total market value based on KB price data — will shift once Olympic Park Foreon is included. The complex comprises 12,032 units, making it the largest apartment development in South Korea by household count. Songpa-gu's Helio City currently tops the KB Leading Apartments 50 ranking with a total market value of roughly 22.61 trillion won (about $16.3 billion). Given Olympic Park Foreon's unit count and recent transaction prices, it is widely expected to surpass that figure by a wide margin and claim the top spot once registration is complete.
