It looks like you already live in San Antonio. A great way to check out some new and beautiful Luxury Homes would be to attend the Parade of Homes at Cibolo Canyons that starts Wednesday, September 3rd. You can actually talk to each of the builders and see their 'product'.
When you get ready to shop around and compare builders, I suggest you look for an agent that is familiar with builders and the luxury home market.

Andy,

All builders charge a different amount for a luxury home! You could see prices from $165 SQFT up to and exceeding $400 SQFT. What is your definition of luxury and do you already have a lot? I have a client building in Anaqua Springs for $250 SQFT including the lot..... As far as luxury builders, you can look into the following: Stadler Custom Homes, MIke Holloway Custom Homes, Burdick Custom Homes, , JMW Homes, Kyle Lindsey Custom Homes and Diamante Custom Homes. These just represent a few builders in the area...

This is going to be dependent on the builder, the area, what you want to spend. There are so many factors to this question. If you are looking for a new builder check out my site and if you need help. Please send me an email.
