The big loft with large windows connects house in the various phase.

The third is that the family is softly connected according to transmitting the sign of each room via the opening of the ceiling.
On the ceiling above the loft, the lights of each room that leaks from the openings are reflected and the sound of the activity is transmitted dimly.
