I don't install HA stuff in my homes for resale value. If it is a deciding factor then great! But it really is for the enjoyment of me and my family. I can't tell you how many time I walk in at night with a handful of kids and groceries and the lights just magically come on. That alone is worth every penny I have spent! Not to mention I have a very good alarm system and my outdoor lights come on at dusk even when I am not here.
Anyway what are all those pipe chases for? Is that for the vac system? Will your builder let you do any of the installation yourself? It's obvious Level 1 is where all the money is being spent. I personally am starting to think whole home audio is overrated. I will tell you why: almost all TV providers (comcast or directv) have just tons of music channels. Sure the speakers aren't as good but get a sound bar if you care that much down the road. I doubt there is a room in your house that you would listen to music that doesn't have a TV. The only place might be outside and that shouldn't be too difficult to correct.
The one thing among many others that I wish I had in my house and it looks like a retrofit option isn't available is intercom. This place is pretty large and we can get lost BUT the biggest issue is my kids are still very young (two under the age of 4) and we still use a monitor to listen in on them. Well half the darn time it is out of range and just drives us crazy! If I had a decent intercom I could monitor each of their rooms all night long...
Maybe the next house!

As for the whole home audio. I agree TVs are compelling for doing audio. However, we have no plans for a TV in the dining room, breakfast room, etc.
The pipe chases are not for the Vac system. They are for future proofing and in many cases they were cheaper than running 2 different wires. I have detailed the pipe chases as I have gone through each room. However, here is a consolidated list:
