We work with architects, designers, engineers, and owner’s representatives on complex residential projects. We see our role as protecting the work, stabilizing the process, and carrying projects through construction with clarity. The Systems That Carry The Work Our Approach from first conversation to long-term stewardship Early Involvement Successful residential projects are shaped early; when decisions are still flexible, sequencing can be set with intention, and the work can be positioned correctly from the start. Alignment Before work begins, alignment is established. Scope, intent, constraints, and authority are clear. Decisions are positioned early, so the project moves forward without hesitation. Planning Our planning anticipates the work before it arrives. Schedules reflect the reality of lead times, interdependencies, and site conditions. Risk is addressed upstream, not absorbed later. Execution Once construction begins, the work follows a defined system. Two-week lookaheads set priorities and sequencing. Decisions are documented and held. Coordination happens in real time, not in response to issues. The site stays organized because the work is planned and actively managed. Quality Control Quality is not inspected at the end, it is embedded in the sequence. Mockups clarify intent. Milestones confirm alignment. Standards are held long before finishes appear. Corrections are rare because the work is right from the start. Closeout Closeout is handled with the same discipline as construction. Systems are verified. Information is organized and transferred. Nothing is left unresolved at handoff. Aftercare Our involvement doesn’t stop at turnover. We remain available as the home settles into use, protecting the long-term performance of the work. SCHEDULING & SEQUENCING Schedules are active tools. Design input is pulled before sequencing is locked. Lead times and dependencies are addressed early. Owner’s reps have visibility into pacing without chasing updates. Two-week lookaheads keep decisions aligned with what’s coming next. Decision Flow & RFIs RFIs are managed through Procore. Questions are framed with context and issued early, so design teams can respond efficiently. Responses are tracked, documented, and carried through the work without reopening resolved items. Using a shared platform keeps communication clear and decisions accountable. Change order Management Changes are identified early and handled formally. Scope, cost, and schedule impacts are outlined clearly. Approvals move through defined channels. We avoid informal workarounds and downstream surprises. quality & Oversight Quality is held through the sequence, not deferred to the end. Mockups, field verification, and milestone reviews give architects and designers confidence that intent is being carried accurately. Owner’s reps have clear checkpoints and documentation to rely on. Site Communication Job sites run through established communication paths. Design teams stay informed without being pulled into daily site issues. Owner’s reps can trust that coordination and follow-through are happening. Our Projects We acquired a grand and classic home designed by a famous architect from a century ago. We have an architect in the city, John Oliver, who works with David Gast’s Architects. They did some fantastic work for us when we built a house in Hawaii, so we completely trust them. For this house, we needed some special upgrades, yet we still wanted to maintain the integrity of the original design. John highly recommended Aaron Gordon Construction as a company that could do very high quality work. We also needed adaptability, because we always change our minds in the middle of construction in order to get to the level that we want. Aaron’s company, and the assigned supervisor, all did superb work, and the sub-contractors were all first rate. I highly recommend Aaron Gordon Construction. — Ed Catmull, President Pixar & Disney Animation Studios 2261 Shafter Avenue San Francisco, CA 94124 (415) 742-4900 License #856802 ©2026 Aaron Gordon Construction Inc.

It is elegant and clean in design and the tempered-glass panels open our view in a way that balusters would only hide. Our designer Mark Pellegrino — who has appeared on seven Curb Appeal episodes for the Home and Garden Television Network — was highly impressed with your work. We also appreciate your professionalism, punctuality and courtesy by keeping us informed about unforeseen circumstances and how to best solve them that were timely and kept us within budget. We wish we had known you when we were involved with our major home remodel. We would happily call you for any future projects, and we would not hesitate to recommend you to our friends. — Doug & Diane. A As the manager assigned to oversee the redesign project, I have worked very closely with Aaron and his team throughout every stage of the project so far. It is my role to ensure the needs and standards of the Association are not only being met throughout this entire process, but to ensure that they are being exceeded. To that end, Aaron and his team regularly carry themselves in the most professional manner, and they work diligently to follow the many rules and requirements imposed on them by our Association. The job site is always impeccably organized so the Residents do not feel too inconvenienced by living amongst a full-scale construction site. The project was awarded to AGC in May, the demolition of the space began in July, and I am happy to report that we are still on target for the project’s completion by the end of the year. From our weekly site meetings to the abundance of communications amongst the team on a regular basis, the cooperation and collaboration that AGC offers has been instrumental in accomplishing our goals effectively and efficiently thus far. Based on our experience to date, I can unequivocally recommend Aaron Gordon Construction, Inc., to anyone in the market, and would like to reiterate our confidence in AGC coupled with the desire to work with Aaron and his team on future projects. — Stephanie Kay General Manager of the Infinity Owners Association Aaron and his crew are consummate professionals and, as important, are very nice people as well. There's a clear thoroughness and honesty to the entire process from start to finish. The quality of the work is first rate and surpassed my expectations. For instance, Aaron found a small problem that I would never have noticed and he decided to fix it, costing him a full day of labor with no additional charge to me. As he put it, "I knew the problem was there and couldn't live with letting it go." At no time was I concerned about the safety of my house while it was under renovation. He's extremely reliable and careful with all elements of working in someone's home while also providing laughs and congeniality that are often missing in the stress of our work worlds. Aaron and his team are also very knowledgeable about the other top professionals in their disciplines and gladly facilitate introductions to these craftsmen. I don't hesitate at all in recommending Aaron Gordon Construction. — Mark C. Press Modern Luxury Modern Luxury Design Awards 9, 2025 Home of the Year Throughout the home, Loczi Design’s vision celebrates tradition through a contemporary lens—refined craftsmanship with a touch of rebellion. “We didn’t want to erase what made the house grand,” says Cooper. “We just wanted to make it human.” When the family saw the finished home, they were overjoyed. “We knew it was going to be great, but we didn’t know it was going to be this badass,” they told the team.

Building a home demands an anticipatory view of the whole and a rigorous care for every detail. Integrity anchors our partnerships. Clarity drives our process. And the work reflects uncompromising craftsmanship, in what’s visible and in the layers no one will ever see. We strive to be a firm whose craft, systems, and collaboration are shaped by seasoned judgment and a consistent, high-caliber execution. If you’re ever left questioning whether your home and investment are in capable hands, we haven’t done our job. project leads, technical specialists,+ field experts 50 Builders Building across SF, the Peninsula, Marin, the East Bay, + South Bay 30 years with a range of scale, + Architectural complexity completed 400 projects What Guides Our Work Discipline When discipline leads the work, the project takes shape with a calm, deliberate cadence. It creates a process you can move through without uncertainty or disruption. Integrity Integrity is reflected in communication, follow-through, and the way a project advances. It’s the standard that brings clarity and trust to the work. Not as an ideal, but as an ethic experienced in every interaction. Craftsmanship When architects, designers, engineers, tradespeople, & homeowners remain aligned, decisions sharpen, progress steadies, & the work carries a momentum you can feel in the clarity of communication & the steadiness of the build. Collaboration Architecture & design form the governing framework of the build. We integrate structure, systems, & details in a way that strengthens the whole, so the home performs as intended & presents exactly as it was envisioned. Stewardship A home can represent years of effort, intention, & memory. Stewardship means treating that responsibility with seriousness; protecting the integrity of the home & leading the project with prudence so its demands never fall to you. A Firm that’s Invested. For decades, AGC has taken on some of the region’s most demanding residential projects. The firm grew not through volume, but through work on homes where sensitive materials and complex architecture require creativity and a practiced hand. Clients have always expected a great deal from us... and we’ve always expected more from ourselves. At the center is a simple conviction; the responsibility is real. It shows in how we communicate, in the problems we anticipate early, and in the continual refinement of how we build. We create an environment where homeowners stay oriented, design partners are supported, and the work progresses with intention and assured control. Our Leadership Our leadership AARON GORDON PRESIDENT & CEO Aaron discovered his love of building early on and later paired it with a strong business background shaped by years working in his father’s manufacturing company and a degree from Sonoma State University. After time spent as a stagehand and set builder, and as his own construction projects grew, he earned his general contractor’s license and founded AGC. He now focuses on high-end, architecturally complex residential work. Outside of work, Aaron finds grounding in rural California — sometimes on the lake with his wife and son, other times in solitude, building, fishing, and tending to his land. BRIAN BURNS OFFICE MANAGER & CFO As Office Manager, Brian leads all project accounting, from contracts and subcontracts to payroll and internal systems. His steady coordination helps AGC operate efficiently, supporting teams and subcontractors across numerous concurrent projects. Originally from California, Brian appreciates the Bay Area’s steady climate after 16 years on the East Coast. He’s happiest spending time with his family, tracking fantasy football stats, or rooting for the Giants, 49ers, and Warriors. BEE RASMUSSEN DIRECTOR OF BRAND & MARKETING As Brand and Marketing Director for AGC, Bee is responsible for shaping how the firm communicates its work, values, and point of view. Her role sits at the intersection of strategy, and storytelling translating the rigor of AGC’s building practice into a clear, disciplined, and resonant public presence. Bee approaches marketing as an extension of the work itself. With a focus on clarity, integrity, and long-term trust, she helps ensure that every touchpoint reflects the care, intelligence, and accountability that define AGC. RICHARD S.

The interior was fully re-planned to recalibrate light, structure, and flow, while steel bi-fold doors, a rooftop hot tub off the primary suite, and a rope floor in the kids’ room mark moments where heavy construction meets craft and play.

A cadence of vaulted ceilings and floor-height glazing creates intimate vignettes of the valley, balanced by the grounded presence of poured-in-place concrete and continuous walnut millwork. The transformation extends outdoors, where a new pool, pool house, and layered plantings knit the home more closely to its site.
