Divide the 281 billion won of construction cost [3] by the 26 units this project actually adds, 482 where 456 stood [4][5][1], and each incremental unit is carrying about 10.8 billion won [2], which at the roughly 1,384 won to the dollar implied by the source's own 281 billion won / $203 million pairing [3] works out near $7.8 million a unit [4]. On any sale price I can imagine for a Mapo apartment, the added units are not the funding mechanism. Spread the same money across all 482 completed units instead and it falls to about 583 million won each, near $421,000 [10], which is a sane number for a rebuilt Han River flat and which locates the product: 456 homes refitted, with 26 new units and four extra basement levels layered underneath them [8].
One floor of height, 28 to 29, and four floors of depth, two to six [8], are not symmetric jobs. Putting four basement levels under a structure that has been standing since 1997 [6] is where a contract price meets a soil report, and it is the line I would want broken out before anyone calls the margin on this.
The more interesting version of the deal is the brand. Samsung C&T built this complex, is now taking it back under Raemian as Raemian La Cieler Hangang [6][7], and says this is the first time it has remodeled its own work [6]. A contractor holding a book of its own 1990s output has something closer to a callable list than a tender pipeline, because it can argue it knows the structure it is being asked to cut into.
There is another way to read this deal: as river frontage, not method. The complex faces the Han River to the southwest, sits within walking distance of Mapo Station on Line 5, and commutes to Yeouido, Gwanghwamun and Jongno [11], and the winning proposal sells permanent views, an art facade shaped after the river's waves, and a sky lounge with rooftop garden across two floors of the new building [10]. If the 281 billion won was priced off that address rather than off the remodeling method, then there is no channel here, only a postcode, and I am wrong.
Kim Myung-seok, who heads housing product marketing at Samsung C&T, framed the win as delivering pride to association members [9]. That is what you say to the people writing the cheques. What matters more is the allocation: a site team and a schedule committed to Tojeong-ro 32-gil [4] for the length of an extension-and-excavation job are not on a greenfield tower elsewhere, and a division that finds this pays will bid the next one.
