The Work Speaks First.

Five finished projects, five different challenges. Every one built with the same standard — quality materials, careful sequencing, and a finish that holds up years after the crew leaves. Scroll through each job's own gallery below.

Project 01

Van Ness Residence

Gardena, CA

A full residential transformation — structural upgrades, interior reconfiguration, and a finish package chosen for how a family actually lives in a space, not just how it photographs.

Modern Kitchen Remodel

Southern California

Spa-Inspired Bathroom

Southern California

A tired bathroom became a private retreat — walk-in shower, floating vanity, and a material palette chosen to feel more like a boutique hotel than a renovation.

How It Works

What to Expect

01

Consult

We meet at the property, understand your vision, and assess what the project requires — scope, permits, timeline, and budget. No sales pressure, just a clear look at what's possible.

02

Plan & Design

Our team develops the design and documentation, handles permit applications, and aligns on materials and finishes with you before a single wall comes down.

03

Build

Skilled crews execute the work with precision — structural, mechanical, and finish trades coordinated under one management team to keep things moving on schedule.

04

Deliver

A final walkthrough confirms every detail meets our standard and yours. We hand over a finished space you're proud of — ready to live in from day one.

Homeowners across Southern California trust 3Days GC to get it done right.

★★★★★

"From the first consultation to the final walkthrough, 3Days GC was professional and communicative the entire time. Our ADU turned out better than we imagined — clean lines, solid construction, and on time. We've already referred two neighbors."

Maria T.
Gardena, CA
★★★★★

"We had our kitchen completely redone — walls removed, new island, quartz counters, the whole thing. The craftsmanship is exceptional. You can tell they take real pride in the details. Our home feels completely different now, in the best way."

James R.
Pacific Palisades, CA
★★★★★

"I was nervous about the ADU permitting process but 3Days handled every bit of it. They knew the codes, managed the inspections, and delivered a guest house that looks incredible. The rental income started within weeks of completion."

Where We Build

Serving the Greater Southern California Basin

3Days GC works across four counties and dozens of cities throughout Southern California — from the coastal corridor of Santa Monica and Manhattan Beach, through the South Bay and Long Beach, into the Inland Empire cities of Ontario, Riverside, and San Bernardino, and out to Orange County's Anaheim, Santa Ana, and Irvine. Wherever the job site is, our process stays the same: a real consultation, a documented plan, and a crew that shows up when they say they will.

Local knowledge matters in this business. Coastal cities carry different permitting timelines and coastal-commission considerations than inland Riverside County builds; ADU codes vary city to city across LA County. We stay current on all of it so you don't have to become an expert in your own municipality's building department just to remodel a kitchen.

Don't see your neighborhood listed? Give us a call — our crews travel throughout the LA basin and Inland Empire regularly, and if your address falls between two service zones, we'll tell you plainly whether it makes sense for us to take it on.
