Thank you for your interest in this home. We actually do sell this house plan through Southern Living. It is called the St. Phillips Place and is a 2500 SF master down. Cost to build is going to vary based on where the home is being built and the specifications so it would be hard to give you a number on that. Here's a link to the Southern Living plan site. Hope this helps and if you have any questions don't hesitate to contact us.
