The Golden Acre. The Foundation Chronicles, #1

Grant Sterling has spent his life fixing everyone else's problems, but when a life-changing windfall hits, he doesn't head for the coast. Instead, he and his wife Maya purchase twenty acres of rugged, untamed terrain known as Sterling Ridge. The Golden Acre documents the first year of their "Self-Build" mandate: a vow to hire no contractors and carve their world out of the raw earth with their own two hands.
Living out of a high-end RV and battling both the elements and a hostile neighbor's zoning dispute, the Sterlings must decide if their dream is worth the dirt under their fingernails. This is more than a construction project; it is the beginning of a decade-long labor to build a family that knows the value of every nail.
