GrindStone Construction is a veteran-owned design-build company specializing exclusively in Accessory Dwelling Units (ADUs) throughout the Raleigh-Durham Triangle region of North Carolina. Founded by former U.S. Army Captain and Apache helicopter pilot Ron Goca, the company combines military-grade planning, disciplined project management, and quality craftsmanship to help homeowners create functional backyard living spaces that increase property value and support multigenerational living.

After transitioning from military service, Ron gained hands-on construction experience working on custom home projects before establishing GrindStone Construction. Today, the company focuses on designing and building code-compliant ADUs, in-law suites, backyard cottages, and rental-ready living spaces while emphasizing transparency, integrity, and customer service throughout the process.
