DL E&C Files Patent Application for Residential Twist Design Technology

[Asia Economy Reporter Kim Min-young] DL E&C announced on the 24th that it has developed a residential twist design technology and completed a patent application. Unlike overseas twist buildings such as The Eleven in New York and Grand Bay Grove in Miami, which feature irregular floor plans on each level, this design maintains the same floor plan to suit the domestic residential market environment. Additionally, it can utilize existing apartment construction methods, ensuring both constructability and cost-effectiveness.

In major overseas cities with numerous high-rise buildings such as New York, Dubai, and Shanghai, geometrically shaped twist buildings have recently gained fame as tourist attractions. However, in domestic residential buildings, there have been no actual construction cases due to the high technical requirements for design, complicated construction management, and increased costs caused by complex floor plans.

To solve the complex floor plan issue, which has been pointed out as the biggest problem of twist buildings, DL E&C planned a circular core at the center of the building and arranged the floor plan surrounding it. The core is the space where elevators, stairs, and facilities for vertical movement of people and equipment are installed, and it is generally made in a square shape. When the exterior walls rotate based on a square core, the floor plan inevitably becomes distorted. However, the twist apartment developed by DL E&C rotates at a constant angle around a circular core, allowing the same floor plan to be implemented on every floor.

Furthermore, DL E&C introduced the post-tension construction method, used in super high-rise buildings, bridges, and nuclear power plants, to support loads only with the core and external columns. This method installs steel tendons from the core to the outer columns to support floors and ceilings, eliminating the need for additional walls or columns inside the units to bear loads. As a result, various flexible floor plans can be freely created, ranging from studio-type single rooms to two-room and three-room layouts according to residents' demands. It also effectively prevents noise between floors compared to wall-type structures. DL E&C verified the performance and technology of the post-tension method by implementing it for the first time in Korea in the super high-rise apartment Acro Seoul Forest in Seongsu-dong, Seoul.

Applying the twist structure to apartments is expected to provide residents with practical benefits such as abundant views and natural lighting. Each floor can secure optimal viewing angles, and units that would otherwise have obstructed views due to surrounding buildings in conventional rectangular apartments can gain additional view rights.
