  • The Unscripted Roadmap: How We Build Together
  • Phase 1: The Discovery (Finding Your Script)
  • Before we pick up a hammer, we pick up a pen. We sit down to discuss your lifestyle, your non-negotiables, and how you want each room to feel. Whether you have a Pinterest board ready or just a few rough ideas, this is where your vision takes center stage.

  • Phase 2: The Groundwork (Site & Design)
  • If you have land in Johnson City or the surrounding hills, we’ll walk it with you to discuss sunlight, views, and placement. Our design team then translates our discovery notes into a blueprint that balances your aesthetic with your budget.

  • Phase 3: The Refinement (Selecting Your Style)
  • This is where the "unscripted" magic happens. We guide you through selecting the materials, finishes, and fixtures that make the home yours. We use our 40+ years of local supplier relationships to find the perfect pieces for your puzzle.

  • Phase 4: The Build (Craftsmanship in Motion)
  • Now, the heavy lifting begins. Our veteran project managers oversee every detail, from the foundation to the roofline. You’ll receive regular updates so you’re always "in the room" without having to be on the job site.

  • Phase 5: The Handover (Your New Beginning)
  • The most rewarding part of the journey. We’ll do a final walkthrough to ensure every corner meets our 1979-2026 standard of excellence. We hand you the keys, and your unscripted life in your new home officially begins.

  • Ready to Start Your Unscripted Chapter? Your dream home shouldn't stay on a Pinterest board forever. Let’s sit down and talk about how we can bring your vision to life in Johnson City.

    ★★★★★
    Absolutely amazing!
    First, I would like to thank Cornerstone Design/Build for being professional builders with the highest quality of workmanship and uncompromising dedication to designing and completing every aspect of the project with an old world eye for perfection. Farrell and his family have been building homes in my area for decades and their crews and subcontractors are dedicated and long term associates who work as a team for the best interests of the customer. Conerstone Design/Build group took on our project and constantly went above and beyond what was required to make the final product not only meet my expectations; but often exceeded them simply because it made the final outcome better. All of this plus an extremely competitive bid compared to other builders both larger and smaller; combined with genuinely warm and friendly interpersonal relationship skills made building this project a great experience.

    Amazing design, exceptional quality
    Cornerstone Disign Build Group built our home in 1986 and we are still pleased with it. We feel it is well built, the finish work is excellent, and the subcontractors were professional. It still looks great today. In 2012, we were ready for a kitchen update and did not consider anyone else for the job. CornerstoneDB Group always listened and worked well with us in what we wanted to accomplish. They were on time, returned phone calls and kept us informed. He stayed within budget with both projects.
