In this country house construction site, the installation was carried out in the space next to the house rather than in the living room. It was structurally located next to the house and used as a multi-purpose room and warehouse. The folding door makes it easier to travel outside, and the folding door is opened and closed to allow frequent ventilation of muddy air in warehouses and multi-purpose rooms to keep them comfortable. You can install a large fix window or a scribe window, but then it is difficult to proceed smoothly.

When the folding door is opened and closed, the indoor space can be used with outdoor efficiency. On a day when sunlight and wind are good, it would be good to fold all folding doors and dry them with natural sunlight and natural wind by hanging them out. In addition, it is made of double-layered glass, which is more durable than regular glass, so it is strong against external impacts and has excellent insulation to block external temperatures.
