Why the Bay Area Chooses Gadi Construction
Our home remodeling project is finally complete (almost 2 year ordeal), but team at Gadi Construction made this navigation manageable.
First shout out to Millie Studnict(Project Manager) . If you've ever gone through a major home renovation, you'd have many questions, decisions, surprises, inspections, and frustration. Throughout the entire process, Millie was always there with an answer, a solution, or simply the patience to walk us through the next step.
What I appreciated most was that Millie genuinely cared. No matter how busy things got, she always returned calls, responded to emails, and kept us informed. There were plenty of times when we were unsure about something, and Millie never made us feel like we were asking too many questions.
The entire Gadi team was great to work with as well. The crews showed up when they said they would, treated our home with respect, and were always courteous and professional. It was clear that everyone took pride in their work.
After dealing with the stress of restoring our home following a fire, it was a huge relief to have a contractor we could trust. The project is now complete, the final inspection has passed, and we're very happy with the outcome.
Thank you, Millie and Lucie and everyone at Gadi Construction..

I just wrapped a primary bathroom remodel with GADI.
Effie was a fantastic design partner – he understood our initial vision and worked with it to come up with something even better that we love.
Nadav did an amazing job managing the project. Communication throughout was constant & immediate via text, and we got the project done quickly and with minimal fuss. His team on the ground was also great across the board.
I'm hoping to work with Nadav & Effie on another project soon, and I highly recommend GADI!

I requested a quote for a job I need done and I had the pleasure of meeting Itay today. He was very professional and kind. Had good energy and reassured me that he will do everything he can for the best outcome. This is more of a review on Itay and I will update if I decide to hire them. But the initial process of getting a quote done was great because of Itay.
I recently hadflood damage to my home which requires extensive remodeling. I called a number of contractors And I was most impressed with Millie from Gadi construction.
Though we haven't gotten to the point of actual construction yet , Millie has come out and given me excellent guidance for remodeling bathrooms, kitchen, living area. I've never done remodeling before so it was nice to have somebody like Millie to
' hold my hand,' and take some of the stress off of making some major decisions. She has since returned phone calls promptly and feels more like a friend helping me rather than a person I hired or may hire.
Whether we use you or not in the end thank you Millie for helping me during this difficult time and I hope others see this review and can take advantage of your nice , kind personality and expertise.
Great experience with Gadi on my bathroom remodel. He hired experienced sub-contractors and made sure they showed up on time. Pricing is fair for the work done.
GADI had helped me in demolishing a big mirror wall and remodeling it into a dinning room. I couldn't be happier with the result. Esther and her crew were just amazing and made my dream came true. Great job!

Redwood City’s inviting atmosphere and light-filled homes inspire additions that are open, modern, and highly practical. We design every space to match your lifestyle and enhance the natural character of your home, making the new area feel like it was always meant to be there.
Here are six popular home addition styles among Redwood City homeowners:
This addition brings more space for relaxation, gatherings, and everyday living. Large windows and open layouts help create a cheerful, airy atmosphere that fits Redwood City’s sunny environment.
A comfortable suite with a private bath and sitting area is perfect for guests or extended family. It provides extra privacy and convenience while adding long-term value to your property.
Ideal for remote workers, this office space offers a quiet, organized area that boosts productivity. With built-in shelves, good lighting, and a peaceful layout, it keeps your work-life balance smooth.
Adding a second story is a great choice for growing families who need extra space. This room can serve as a primary suite, children’s room, or a quiet bonus room with great views.
A kitchen addition opens up your cooking and dining space, giving you more room for storage, meal prep, and entertaining. It creates a warm, functional environment for families who love spending time in the kitchen.
A sunroom offers a cozy spot to enjoy morning light, reading time, or peaceful evenings. With wide windows and inviting finishes, it connects your home to the outdoors in a beautiful and relaxing way.

The cost of a 20x20 addition, which totals 400 square feet, is highly variable based on the scope of work, materials, and local labor rates. In the Santa Clara CA and San Jose, CA area, a basic shell addition typically ranges from $150 to $250 per square foot, placing a 20x20 project between $60,000 and $100,000. This estimate usually covers framing, roofing, basic windows, and a concrete foundation. If you require a fully finished space with electrical, plumbing, HVAC, insulation, drywall, and flooring, the cost can escalate to $300 per square foot or more, reaching $120,000 to $150,000. For a precise budget, it is essential to consult with a licensed contractor like Gadi Construction to evaluate site conditions, permits, and design specifics.
The 30% rule is a guideline suggesting that the cost of a kitchen or bathroom renovation should not exceed 30% of your home's overall value. This principle helps homeowners avoid over-improving a property for its neighborhood, which can make it difficult to recoup the investment upon resale. For example, if your home is valued at $500,000, you would aim to spend no more than $150,000 on a major kitchen remodel. While this is a useful benchmark, it is not a hard rule. For expert guidance on balancing budget and value, review our internal article titled Remodeling Your Kitchen: What You Need To Know. At Gadi Construction, we often discuss this rule with clients to ensure their project aligns with both their lifestyle goals and long-term financial strategy.
When communicating with your contractor, avoid saying things that can undermine the project or create misunderstandings. Never tell them "I can get this material cheaper myself," as this disrupts their supply chain and warranty responsibilities. Avoid saying "Just do it quickly" or "I don't care about the details," as this invites shortcuts and poor workmanship. Do not reveal your maximum budget, as it removes your negotiation leverage. Also, avoid saying "My friend can do it for less," as this disrespects their expertise and pricing structure. For a deeper understanding of professional communication, refer to our internal article How To Work With Contractors: A Practical Guide For Homeowners, which provides essential guidance. At Gadi Construction, we emphasize that clear, respectful dialogue is the foundation of a successful project.
For a 1,000 square foot addition in the Santa Clara and San Jose area, you should budget between $300,000 and $500,000. This wide range depends on the complexity of the build, the quality of finishes, and site-specific factors like foundation work. The average cost per square foot for a standard addition typically falls between $300 and $500. This estimate includes structural work, permits, and basic materials. For a more precise breakdown, we recommend reviewing our internal article titled 'Prefab Vs. Custom ADUs: Santa Clara Cost Analysis' at Prefab Vs. Custom ADUs: Santa Clara Cost Analysis to compare costs. Gadi Construction advises that custom additions with high-end finishes will push the budget toward the higher end, while simpler layouts can reduce costs. Always obtain multiple bids to ensure competitive pricing.
