In which parallel world do you get strange looks for doing it yourself?
Well, I was already given weird looks because I pulled in network cables, satellite cables, and speaker cables myself. Of course with installing sockets, empty conduits, etc. the whole package. Some people even raised their eyebrows so high it was like they broke them.
Before I built, I watched house construction sites in the area for years and then went by 1-2 years after completion to ask how their experiences were after a year. Some people configured the entire house IN ONE DAY (everything, every socket, every tile), then transferred the money and maybe viewed it from the outside 1-2 times before moving in.
