This system installs a transfer floor composed of composite beams and perimeter beams made from POSCO special steel building materials on apartment rooftops to distribute upper loads, enabling the implementation of various floor plans such as penthouses. Even in cases where the site is limited and horizontal or separate building extensions are restricted, it is possible to secure additional units for general sale.

Existing remodeling vertical extensions involved vertically extending the load-bearing walls of the lower structure as they were, which limited the floor plan configuration of the vertically extended upper structure due to the narrow spacing of the walls.

POSCO E&C expects that this new technology will reduce the financial burden on association members and improve project profitability.

POSCO E&C possesses various remodeling technologies. In 2020, it was the first in the industry to develop a technology for connecting new and old remodeling slabs, and this year, it signed a business agreement with LG Electronics to develop remodeling-customized home appliance technologies. The newly developed construction method has also completed patent application.

Additionally, POSCO E&C holds titles such as the first construction company for remodeling vertical extensions, number one in remodeling order performance, and number one in completed and ongoing sites. It is analyzed that proactively preparing for the remodeling market as a future growth engine was effective. Since establishing a dedicated remodeling department in 2014, POSCO E&C has accumulated orders for a total of 38 sites and 39,585 households.

A POSCO E&C official stated, "Unlike new construction or reconstruction, remodeling projects require advanced technology and experience from design and permits to construction. By utilizing the newly developed system, we will solidify our leading position in remodeling and continue to add value to the world by pursuing challenges in spatial innovation through continuous technological development."
