We Build the Homes Ourselves

We are a full-service organization and unique among San Diego custom home builders in that we don’t hire contractors to build for us. All of our homes are constructed by Tourmaline employees. By doing the work ourselves, we achieve far greater control over quality and workmanship than builders who contract their work.

What People are Saying

  • We are absolutely thrilled with the house that Tourmaline built. It caters to our every need and the attention to detail and craftsmanship are second to none.

    Andy & Helen W.

  • Tourmaline's homes stand far above any others. Inside, outside, the quality and workmanship are superb. Every little detail and finishing touch, perfect! Finally, the service and kindnesses were exceptional.

    Del H.

  • I’ve been in a Tourmaline home for almost three years and I have absolutely no regrets. When I called a year and a half after the purchase, they immediately returned my call, answered my question and offered assistance and guidance.

    Sheryl K.

  • We bought a home from Tourmaline Builders and have been very satisfied. Ben and Jake are both genuinely committed to building great houses. They don't cut corners and were very responsive and passionate about doing great work.

    Anshu B.

  • I recently purchased a house from Tourmaline Builders and have been so pleased with the home. What impressed me most was the follow-up after closing. This group takes pride in its work and cares about the homebuyer.

    Daniel C.

  • Tourmaline Builders stands by their work…Everyone is an employee, they don't use subs, so the care and control they have is shoulders above other builders.

    Jenny N.

  • Tourmaline built a terrific house. I couldn't be more satisfied.

    David P.

  • I have worked with many builders and developers over the years and Tourmaline Builders rises to the top every time. They go out of their way every time to ensure work is done to high standards — the highest standards in southern California.

    Kelly K.

  • In my house search my wife and I looked at many homes, but none came close to using the same quality of materials that Tourmaline Builders used on my new house.

    Phil W.

  • From the initial meeting and through every step of the process, Tourmaline was a pleasure to work with — responsive and attentive.

    Jim L.

  • My clients truly love their new home. It is just right! Thanks!

    Kathie R.

  • Working with Tourmaline has been great! There was great attention to detail and high-end finishes. They were very responsive, honest and straight-forward.

    Maneesh B.

  • We’d looked at lots of homes. But this one just stood out. The custom cabinetry, the lighting, the fireplace, even the landscaping were all extraordinary. And Tourmaline was so attentive and made sure that everything in the house was perfect.

    Erik & Natalie D.

  • My wife and I couldn't be happier with our new home. We looked at close to 50 homes and nothing compared to the one Tourmaline built. Everything looks great — the kitchen, yard, floors, bathrooms, and everything in between.

    Dave G. & Nikki B.

  • We had just about given up on finding the kind of attention to detail we wanted. But everything from the inlaid tile in our bathrooms to our beautiful hickory floors make this house the home we really hoped for.
