Nephew built a steel framed home for him and his family. It was a fairly large 2 story home but it took 4 wired wifi routers to cover the home because of the steel framing. Wifi signal would only really have any strength 1 room away from a router. Ended up with one in each corner room. 2 upstairs and 2 downstairs.

Saw another home being built I thought was cool. All of the outside walls were styrofoam forms and filled with concrete. Then it was bricked outside of that. The large master closet was 10 in thick concrete for a safe room.
