Usually when we build interior doors for houses, it is a mixture of sliding doors and interior doors with a frame. Where there is plenty of space, ordinary interior doors with a frame are used. Where it is crowded, where you do not want the door leaves set up or where there is a sloping roof, it can fit better with sliding doors. In older houses that are being renovated, there may be existing sliding doors that need to be replaced.

If you can not build in the sliding doors, surface-mounted sliding doors can be an option. There are stylish and well-designed suspension brackets for mounting the sliding door on the outside of the wall.
