Pentomonium towers - Yongsan International business district
Chicago architects Murphy/Jahn have designed two towers under one roof for the western side of South Korea’s new commercial centre, the Yongsan International Business District of Seoul. Containing mainly apartments, the 320-metre-high Pentominium skyscrapers will conceal sheltered gardens and balconies behind the lattices of glazing that make up their exterior walls. The firm was commissioned alongside fifteen other architects to design towers for the Yongsan International Business District, which was masterplanned by Daniel Libeskind and which is the biggest urban development project in South Korea. Due for completion in 2024, the masterplan was commissioned by South Korean developer DreamHub.
Situated on a high-profile site in the western side of the district, plot R5 houses a signature topend residential building, 320m in height, which will attract the most exclusive clientele from both Korea as well as the rest of the world. These Pentominium units will provide unsurpassed urban living experiences, with spatial and privacy features normally associated with individual houses.
In order to maximize window views and create a sense of exclusivity through minimizing the number of units per floor, two slender towers were chosen for the design. A simple square footprint provides the geometry basis for each tower floor. To take advantage of the desirable vistas to the southwest, the cores for the towers are shifted off center towards the northeast elevations. The resulting U-shaped usable areas can then be divided into one, two, three, or four units per floor, most with view access to the southwest.
Around each unit, the enclosure façade moves in and out from the square tower footprint to create customized bay windows, wintergardens, and enclosed balconies. An exterior screen of vertical and horizontal bars is located outboard of the balconies. The primary module of the screen is 5.0m tall by 3.0m wide to align with the façade geometry. In areas where increased privacy is preferred, such as bedrooms and bathrooms, additional vertical bars are added within the primary module.
At various heights in each tower, structural bays are carved out of the sides of the building enclosure to create four-story high skyparks. Each skypark will be developed to provide a distinct amenity experience for the Pentominium residents, from a place of meditation, to an exterior lounge, and a sporting/exercise zone. Open joint glass panels in the exterior screen here help to temper these spaces climatically, while still maintaining an exterior experience for the residents.
Amenity functions are located at a mid-height level of the towers. A platform with both interior and exterior areas connects the two towers here, allowing residents to have their own private garden and lounge area in the sky. At the top of the towers are private roof gardens for the ultraexclusive single floor unit super villas.
Officetel units, with circulation separate from the Pentominiums, are located in the bottom eight floors of the east tower, as well as an adjacent four-story podium building. Secure parking for the Pentominium units is located in the basements below, with direct elevator access to each floor as well as the retail concourses below grade.
