Atlanta Custom Builders Recos? J.Tucker Homes?

After over a year of looking for a new personal residence, I'm now considering building from scratch.  J. Tucker was recommended to us but I'm wondering if anyone has had experience with them or can recommend any other custom home builders in the metro Atlanta area?  

We'll likely be building in Cascade and don't want a cookie cutter cul de sac development but instead are eyeing 1 acre + plots of land that will allow for a bit more of a custom feel with privacy.  If anyone has thoughts on building from scratch versus finding something existing and rehabbing, please chime in!
