When you say “I’m building a house” what does that actually mean?

If you are using one of the large builders you have some obstacles that will likely preclude you from achieving your goals.

If you have a builder constructing your home on the property you own, speak with your builder. He likely has experience with a low voltage company that can set you up with what you need and will know how to work with the builder wo conflict.
