using the same color and tonality of the other areas of the house (for what can i see in the pictures) wood and leather materials, and introducing some timber tress (true or fake, it's your choice) for lighting , using the same existing wiring i fixed some industrial lamp to wooden beam. a modular bookcase and design armchair (Barcelona - Mies Van der Rohe, tobacco color) for stairway wall. I left undercover every system on the wall, I changed the lamp on the balcony, extending the wiring to wooden beam, and left free the area under the balcony because of the skylight and the wall window. In the same way i replaced the spotlight on the roof. I fixed a big TV on the S wall because in this place in less disturbed by natural light in every time of the day
