This is an example of construction after basic interior construction. As wallpaper, floorboards, home appliances, and appliances were located, the existing frame may be damaged even if the construction is carried out carefully after removing all existing frames. Therefore, the existing shot seat should not be removed and the folding door and hinge should be installed.

The method of construction of the non-removal lower rail is to insert the folding door lower rail on top of the existing high shot, so there is no additional demolition cost, and there is no damage to the wallpaper, floorboard, marble, etc., which have already been constructed internally. This method of construction is called "one-day construction method" because the time of installation of folding doors is fast as the method of construction is called "one-day construction method is called "one-day construction method".

The veranda folding door was selected as a white-colored frame and was constructed with an unbiased deployment method.
The multi-purpose room has been constructed with a hinge with a mask glass, and although it is not visible in a private way through a semi-transparent mask glass, it is less stuffy because it is not completely opaque.

Overall, the construction is done with a white frame to make the atmosphere of the house brighter and brighter.
