Wow, those houses look pretty nice. Not my style though. Too much foo-foo. I like things a little (lot) simpler. I guess the engineer in me wants function over form. Too many places for the hurricane winds to take hold and launch portions of the house into the neighbor's yard! I am putting in a couple dormers upstairs though, that should break up the roof line a little bit.
Here is the house I live in now:
I like the style and layout, so I was using it as a base. I added another garage bay, made the whole house a little deeper, added a bath, and added another MB suite upstairs. Keep the lines simple, the house functional, and construction costs minimal.
