R-Squared Construction has been crafting high quality custom homes in the Asheville area since 2003. By choice, we are a boutique residential builder in WNC. Our experienced team of career carpenters prefers to focus on a few projects at a time to ensure that each job is completed with the highest attention to detail. It is our mission to collaborate with clients, architects and designers to provide customers with a beautiful home that they will continue to fall in love with for a lifetime.


Joel Barto, the owner of R-Squared Construction, has over 25 year experience in the construction business. A finish carpenter with extensive knowledge of every facet of home construction, he can be found getting his hands dirty on every project. Joel's constant presence on the job site honors our commitment to finely honed craftsmanship; it's key to consistent communication with our customers through the entire building process.


We have a deep respect for our clients' needs, questions, and dreams. It takes no effort to profess honesty and integrity, so we encourage potential customers to seek out testimonials from our past clients. When we undertake a job, we do so knowing we are taking part in fulfilling a dream and that our clients are entrusting us with their most expensive asset.


R-Squared Construction is a residential builder in the WNC area with a concentration in Buncombe County. Since opening the business in 2003, our portfolio has included:
  • Custom Homes
  • Additions
  • Whole Home Remodels
  • Historic Renovations
  • Gourmet Kitchens
  • Bathroom Remodels
  • Exterior Projects
  • We couldn’t have made a better choice. Joel had a lot of integrity and took a personal interest in our project, even though R-Squared was simultaneously building several homes. Everyone who touched our project took great pride in what they did, resulting in a spectacular end product.
