A folding door and a hinge door were constructed in the entrance space on the first floor. It is an entrance located right next to the store on the first floor, so you can separate it further and use it as an interior space whenever necessary with a folding door and a hinge door. When moving a lot of luggage or when a wide entrance is needed, the folding door is opened so that it can be easily moved by making it a wide entrance.​

It is sometimes used as an open space without installing an entrance door. In that case, we have to accept all external environmental conditions as they are, so all seasonal external temperatures flow in, and the damage to the items stored in the entrance and exit spaces is high.Therefore, the installation of folding doors and hinge doors can make you feel uncomfortable depending on the weather, such as rain, snow, and strong sunlight, and the folding door and hinge door can be separated into spaces to block external environmental factors.

When both the hinge and folding doors were opened, it folded neatly as if there were folding doors and hinge doors, so there is no obstacle to traffic.
