Commercial + residential
construction since 1979.
01Who we are
spaces with purpose,
precision and permanence — for owners who plan to keep
what we hand them.For more than four decades, Stonewk Construction Group has delivered towers, plants, schools and hillside homes across Southern California. We plan like engineers, build like craftspeople and stay on call long after the keys are handed over.
02Sectors
Offices, hospitality and civic buildings delivered in dense city blocks without stopping the street around them.

Logistics hubs, manufacturing plants and cold storage — tilt-up, steel and super-flat slabs built to run 24 hours a day.

Custom hillside homes and multi-family buildings, detailed with the same discipline we bring to a tower.

One contract and one team. Architects, engineers and builders aligned from the first sketch to the keys.

Project counts and figures are demo values.

05How we work
We coordinate every stage from planning and permitting through construction and hand-over — one team, one schedule, one number to call.

Every project begins with a clear understanding of the site, the people and the purpose behind the building.

We coordinate drawings, engineering and agency reviews so permits arrive when the schedule needs them.

Self-performed concrete and steel, a superintendent on site every day, and a daily safety brief before the first pick.

Commissioned systems, trained facility teams and a complete digital record — and we stay on call through the warranty.
06Safety & trust
Every worker goes home the way they arrived. Every owner is protected by bonding, insurance and a quality programme audited by third parties.
Safety, bonding and insurance figures are demo values.
07About
Stonewk Construction Group began in 1979 as a three-person concrete crew in Boyle Heights. Today 600 people work across three offices, and we still self-perform the work that matters most: concrete, steel and the finish carpentry clients touch every day.
We are family-owned. The people who sign your contract are the people who answer the phone when something goes wrong — and that hasn’t changed in two generations.
—Client words
“They kept the street open, the tenants happy and the schedule honest. Thirty months, zero surprises.”
“Stonewk’s superintendents ran the cleanest industrial site we have ever had — and handed over two weeks early.”
“Building on a canyon is hard. They made it feel calm, and the house is better than the drawings.”
08Careers
Contractors are always hiring — and we promote from the field. Two of our three regional VPs started as apprentice carpenters.
