I have no experience with Sonos, but i think this is the best choice.
Building new house, at first I need some basic knowledge (minimum setup in al rooms) to be able to discuss further.
In living room will be TV and projector with free-standing two stereo speakers. Sonos as a cinema system (in wall or ceiling).
Depending on the specifics of the object, there can be no cables from house to outdoors (to second floor jacuzzy zone or fireplace zone, steam house).
All equipment is planned in technical room no 11.
Proposals can be drawn by hand (easer to understand for me), with the SONOS equipment layouts /schemes.
The area in square meters is indicated next to the rooms numbers. The first floor from one side to the other is 26 meters horizontally and 23 meters vertically. Little bigger image in links

second floor link
thank you for your help!
