It's going to be a remarkable house. Though not yet complete, it's already on the market and I will blog it.
For now I'll give you a hint from the rooftop deck on a very hazy summer day.
The highest new house in Atlanta is on a ridge-top, poking its roof into Atlanta's famous green canopy. You can see an intervening ridge here. The distant buildings sit on a 3rd prominent Atlanta ridgeline.
