When you dream of an outdoor kitchen that looks incredible and actually lasts a lifetime, you team up with true masters of the craft. For more than 15 years, GPT Construction Masonry & Design has been Sunstone’s rock-solid partner in Northern California — creating stunning full-masonry outdoor living environments that perfectly showcase our premium 304 stainless steel grills, burners, and cabinet systems.
Family-owned and operated since 2003 with over 25 years of masonry experience, GPT Construction is led by Master Mason Geoff Thomas. Geoff personally works on every project from start to finish, bringing generational knowledge and hands-on passion to every build. Their motto says it all: “Built To Last” — and they mean it.
Why Full Masonry Beats Prefab — Every Single Time
Geoff Thomas is setting the record straight: pre-fab metal studs, wire mesh, and veneer systems simply don’t hold up in Northern California’s weather. GPT builds exclusively with real, full masonry construction — engineered with fortified rebar and time-tested techniques passed down from generations of master masons. The result? Heavy-duty poured-in-place concrete counters so strong “you can dance on them,” custom fireplaces, wood-fired pizza ovens, and complete outdoor kitchens that will enhance your home’s value for decades.
They specialize in custom masonry outdoor living getaways across the Sacramento to Placerville to Auburn triangle and the beautiful Sierra Foothills. Every project is unique — tailored exactly to your space, lifestyle, and vision.

The Perfect Marriage: GPT Masonry + Sunstone Performance
GPT Construction installs Sunstone equipment as the heart of every outdoor kitchen they build. Our heavy-gauge 304 stainless steel Ruby Series and Pro-Sear grills, True-Hybrid charcoal/gas/wood/pellet grills, Power Cirque burners, and Signature stainless cabinet components deliver unmatched durability, easy cleaning, and legendary cooking power — all seamlessly integrated into GPT’s bomb-proof masonry structures.
Picture this: a massive poured concrete island housing a Sunstone 4-burner Pro-Sear grill with infrared searing power, a built-in fridge, and a GPT handcrafted full-masonry pizza oven. Timeless beauty meets Texas-tough innovation. That’s the combination that turns ordinary backyards into extraordinary outdoor living spaces.
