Help me plan my new tank!

[pjlovesbaskets]

Our house is up for sale and we are thinking about building. Any suggestion for fish tank installs? I currently have a 125g beginning reef and an empty 55 I want to fill. I am open to all suggestions including changing tank sizes. Would love to see pictures or references to posts on this site. Help me plan my new tank or confirm that I should keep mine.
Questions to be answered....Should I upgrade?
Should i build it in the wall?
What do you love about yours?

"should I upgrade?"
What do you want to keep?
"..wall..."
I looks nice but a little more cost and work.
