You love your location. You love your neighborhood. You love your views. But your family has grown, your needs have changed, or you simply need more space to live the way you want.
We specialize in home additions that seamlessly integrate with your existing structure, whether it’s expanding up with a second-story addition, extending out with new living space, or creating a dedicated primary suite. From foundation excavation to architectural finishes, we handle the structural complexities and design coordination that ensure your addition feels like it was always part of the home.
The challenge with additions is making the new and old work together structurally, aesthetically, and functionally. Our team’s architectural training and construction expertise ensure that your addition blends seamlessly with your existing home.
Jorge Escobedo, our Managing Director and Estimator, brings architectural oversight to every addition, ensuring the design respects the original architecture while meeting modern building codes. Jairo Laverde, our Project Manager, coordinates between your architect, structural engineer, and our field team to ensure the transition between old and new is flawless.
Every evening, you receive a shared Google Photos album with progress shots and drone footage. You'll always know exactly what happened on your site that day.
We don't work on time-and-materials. After our Professional Services Agreement (PSA) phase—a paid feasibility study that investigates site conditions, permitting, and budget realities—we provide a fixed-price contract. No surprise invoices. No scope creep.
Our detailed project schedules are updated at least twice monthly and shared with you and your architect. You'll see every milestone, every lead time, and every built-in buffer.
We conduct weekly meetings with you and your architect to review progress, solve field conditions, and ensure continuous alignment throughout construction.
We maintain exceptionally clean and organized job sites, including neatly managed fencing, wrapped portable toilets, and proactive neighborhood communication to minimize disruption.
Adding to your home in Berkeley and Marin County means navigating setback requirements, height limits, floor area ratio (FAR) calculations, and complex structural codes. We are experts in the permitting and engineering complexities of the Bay Area, ensuring your addition meets all requirements without compromising design.
From coordinating with structural engineers on foundation reinforcement to managing Title 24 energy compliance and accessibility requirements, we handle the bureaucracy so you and your architect can focus on the design.
We protect the design intent while solving the structural realities of existing homes. From early feasibility studies to the final reveal, we ensure the budget supports the vision rather than compromising it.
We engage during design—not after. Our team provides real-time feedback on structural feasibility, code requirements, and budget implications, significantly reducing surprises during construction. We see architects as partners, not vendors, and we collaborate with top-tier Bay Area design studios on additions that honor the original architecture while creating beautiful new space.
Most home additions take 4–12 months from design through completion, depending on project scope, permitting complexity, and material lead times.
Second-story additions are more costly than ground-floor expansions because they require structural work on the first floor—including new framing, foundation reinforcement, additional mechanical/electrical/plumbing systems, and new finishes throughout the existing space to tie everything together.
The average size for a home addition in Berkeley and throughout the Bay Area is around 500 sq ft. This space is typically enough to significantly enhance your living area, whether adding a new bedroom, extending your living room, or creating a dedicated office space. It’s a popular choice for homeowners looking to expand their living space without the need to relocate.
For a 500 sq ft addition in the Bay Area, costs usually range from $450,000 to over $650,000. This estimate depends on factors like the type of addition, the materials chosen, and any special upgrades you might want.
We ensure every addition is a perfect blend of functionality and aesthetics, tailored to your needs and budget.
Completing a home addition in Berkeley takes between 7 to 9 months. This time frame includes everything from initial design to final touches, ensuring the addition seamlessly integrates into your existing home.
