Made me wonder about 'service walls' which would be a pre-built piece that was incorporated into a regular build, but had wires/pipes/etc already built in. You could have a "spine" of a house setup like this, or like a hub, but that doesn't help power points or piping on other walls of a room. So much of the hassle and cost is that we are building almost a unique house each time and everyone has their own idea of what they want in a house, or uses that unique aspect to express themselves.
