I wish you the best of luck with the house, Greg and Gail!
Landscaping, eh? I used to do that when I was much younger. We had 300 acres we landscaped. Oh yeah, it was a dairy farm.
I was seriously considering an "L" shaped aquarium. I love the way they look, especially with the curved front corner. But then I realized that I love both of our tanks too much to choose. So the predators get one tank, the reef another. The predators will probably hang out in the corner as close to the reef as they can get with drool hanging out the their mouths.
Of course, I could always send Patti down for a weekend and you can give her a hammer and she will make room for a tank as big as you want!
