The design that results from this collabora- tion is the best of all worlds—it looks gorgeous, it is as affordable as possible, and it can be built on time and within the budget. To make this happen, we need to be involved early in the proc- ess—and we look forward to working with you! WWW.CAROLINATIMBERWORKS.COM 828.266.9663 .
