Unmatched Quality

We have an unwavering commitment to excellence – in design, in the caliber of materials we use, and in our craftsmanship. And that commitment is reflected in the final product – an extraordinary home that we’re proud to have built and you love living in.

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.


Award Winning Design

Our commitment to superior design is reflected in the numerous awards we have won: we are a five-time winner of the Icon Award for custom home design; a past finalist for the National Association of Home Builders’ nationwide award for best design of a custom home; we have been named the Building Industry Association’s San Diego Custom Home Builder of the Year.


Wide Range of Home Styles

From Modern Farmhouse to historical Craftsman, traditional Cape Cod to cutting edge Contemporary, from classical Spanish or Mediterranean to Mid-Century Modern, we have extensive experience in a wide range of styles and can customize to fit your taste.


Sustainable Design

Tourmaline built the very first spec home in San Diego to earn the prestigious LEED certification for sustainable building practices. We apply the same commitment to energy efficiency in every home we build.
