A renovation of 20-year-old apartment.  A 3-bed-rooms LDK apartment was transformed to a 2-bedroom special-LDK.  A Japanese tatami room was replaced with a carpet-floor study.  A new opening was added to a wall between the entry way and the study.  A major part of the walls was strip down, and the original structural concrete walls were exposed.  All the plastic finishes on the doors, the walls and the ceiling were removed.  Together with the textured natural plaster walls and linen wall covering, the new space gained the full earthy feeling, to give the residents a chance to reset their biolythm.
