Frequently Asked Questions

Grander Construction builds custom homes and outdoor living spaces across the Upstate of South Carolina, including Greenville, Spartanburg, and surrounding communities. We also serve select areas of Western North Carolina.

Yes, we do. At Grander Construction a barndominium is built the same way as a traditionally framed home. To us it is simply a style choice, not a different type of construction. We use the same methods, materials, and attention to detail that go into any of our custom homes. This allows you to enjoy the open layouts and unique design features that often define barndominiums, while knowing the structure is built to the same high standards of quality, durability, and comfort that we bring to every project.

Yes. We work alongside trusted realtor partners to assist clients in finding the right property for their custom home. This collaboration helps ensure the land you choose is a good fit for your design goals, budget, and construction requirements.

Yes. We welcome plans brought to us by the homeowner and are happy to review them for feasibility, budgeting, and construction readiness. For custom homes, we typically partner with a residential drafter or licensed architect to develop a complete set of build-ready plans. For garages, detached structures, and outdoor living projects, Grander offers in-house design services to help move projects from concept into construction. When required, we also coordinate engineered approvals for specific structural or site-related elements.
