My wife and I are getting ready to build a new home in the Spring and I'm about to meet with our architech. Does anyone here any bits of wisdom to offer?

I know I want to network the home and will probably run conduit throughout, even to the garage, but I'm not sure if they should all run to one place? I guess I can look that up. But any tips on anything from doorways to counterspace would be appreciated!
