I am in the process of building a home and would like to install the right components in order to have a "smart" home. Since budget is a concern for me, as well as for most people building a home, I want to install the least amount up front but be able to scale it upward down the road without a forklift upgrade.

I would think wiring runs etc. would be the most critical part to do up front. It is difficult to go back and tear up walls to install wiring. I would like any advise on a place to start in my research on this topic.

Also, the system I would like to install would allow me to control lighting, climate, whole-house music, etc. without breaking the bank.

Thank you for the input!
