This is a new construction project for SYNEGIC Corporation, a manufacturer of structural screws. We were asked to propose an advanced architecture that would expand the possibilities of wooden construction. We wanted to create a place where the way employees work can influence each other and create a lively dialogue and a sense of solidarity, so we planned a space with a large 18-meter roof and various spaces arranged here and there.

By moving the floor level along the terrain in relation to the roof structure, we gave the office the sense of place it needed to function in a building with a large roof, which tends to be uniform, such as a small space that feels like an attic, or a large space that feels connected to the whole space. The aim was to create a company building that allows for the exchange of information within the company through a loose space and flow lines.

The roof is made up of 105 mm wide residential laminated timber trusses lined up at an angle and joined together with triangular CLT panels to create a soft and organic atmosphere. For the flat trusses at different angles, the use of CLT panels eliminates the need for custom hardware, and we proposed a rational method of pre-cutting the trusses at the factory and joining them with screws on site. By using CLT panels, which are often used for walls and floors and give a heavy impression, for a lightly designed three-dimensional roof, we were able to practice a new use of CLT, which has two characteristics: design and structure.

In addition, with the cooperation of employees and local residents, we held a workshop called the "Seed Gathering Project," in which we collected seeds of native species that grow in the surrounding mountains and regenerated them on the site. It is hoped that the long-term growth of native forests will lead to the regeneration of local identity.
