A public office building using Nail-Laminated Timber (NLT) is under construction for the first time in Korea. The 4-story hybrid office building at Sancheong-gun, Gyeongnam province, was converted from the original concrete design to mass timber structure using glulam post & beam with a structural NLT floor system. The project is slated to be completed in early 2020. Canada Wood Korea will provide continuous support to this project.

This office building at Sancheong-gun, Gyeongnam province is a 4 storey building (2 stories underground and 2 stories above ground) with a total floor area of ​​1,449.74m2. Although the building was originally planned with reinforced concrete, Mr. Choon-Sik Lee, Lead Architect of DOMUS Architects has changed the two floors above ground with mass timber structure using glulam post & beam with structural NLT floor system. This is because large-scale wooden structures are competitive enough for both structural and cost comparison with reinforced concrete structures in addition to its environmental advantage, such as sustainability, low carbon and energy efficiency.

Nail-laminated timber (NLT or nail-lam) is a century-old construction method that is undergoing a design renaissance. It can be found today in many historical buildings as well as in compelling new projects of all sizes, where its structural performance and design elegance come together to create inspiring spaces.
