The target of this study is the reconstruction of the night zone by creating Master bedroom with walk- in closet and the direct access to bathroom ,(the bath must have an entrance and from the corridor, a second bathroom, a bedroom with two beds and finally a office room that can sleep a person and the cat of the house too. Also space for laundry and a storege for cleaners. All these we did with minimum demolition and lower costs, as shown in the drawings. One final observation on the day zone, it would be better the library moved to the north west wall so there is a nice picture in the background of the room, turn 180 degrees the sofa to accommodate their guests and have a greater field of vision and even placed two armchairs and furniture of the TV to the wall that was the library before.
