Custom Home Dreams? RGB Custom Home Builders began in 1986 as a custom home builder, and it has become very much a part of who we are. We seek not to limit our Customers choices, but to expand them. Want a gym floor in your living room? A dojo above your garage? A swimming pool in your basement? Or maybe your hearts desires include elegant backlit bookshelves flanking your stone fireplace. Whatever your dream, share it with RGB today!
