Worked very closely with Millie and team on a remodel of our 2000 sq feet property in Milpitas and it was a delight to work with Millie and the entire team. Millie took the entire burden off of our shoulders and had her team do some amazing work and a very tight schedule. The work the team has pulled off is amazing and we are extremely happy with the work and looking forward to moving back in.

We recently completed a renovation project with GADI Construction, and I couldn't be happier with the results and service.
From the very beginning, the team truly listened to our vision. They are incredibly flexible and capable of customizing everything to meet specific needs–no matter what idea we threw at them, they always found a practical, creative way to bring it to life. On top of their top-tier craftsmanship, their pricing was very fair and transparent throughout the process.
A special shoutout to our project manager, Nadav, who was exceptional. Nadav's attention to detail is unmatched. He handled all communication with the crew effortlessly and was constantly proactive with quality control, catching and resolving small details before they ever became issues. Because of his dedicated management, I was able to stay focused on my own work and personal life without the typical stress that comes with remodeling.
If you are looking for a reliable, customer-focused contractor that delivers top-quality work at a fair price, I highly recommend GADI Construction and Nadav!
I requested a consolidation to replace our kitchen countertop/ backsplash/ sink. Itay from GADI, did a wonderful job explaining the project process, suggesting different ideas, cost and timeframe.
Thank you Itay!

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..

This addition creates a bright, spacious environment perfect for relaxing, family gatherings, or entertaining. Large windows and open layouts bring in natural light, making the space feel warm and welcoming.
A complete suite with a bedroom, bathroom, and cozy lounge area offers guests comfort and privacy. It’s a smart upgrade for families who frequently host visitors or want a flexible rental opportunity.

A 20x20 addition, totaling 400 square feet, typically costs between $80,000 and $160,000 or more, depending on the scope and finishes. This estimate covers basic framing, roofing, siding, insulation, drywall, flooring, and standard electrical and plumbing. For a simple, single-story shell, you might be closer to the lower end. However, if you are adding a master suite with a bathroom, kitchenette, or high-end materials, costs rise significantly. Permits, foundation work, and HVAC extension also factor into the total. For a project of this size, it is wise to get a detailed quote that accounts for your specific layout and local building codes. Gadi Construction recommends budgeting for a 10-15 percent contingency to cover any unexpected structural or utility needs.
The 30% rule is a general guideline suggesting that the cost of a kitchen or bathroom renovation should not exceed 30% of your home's total value. For example, if your home is valued at $500,000, you should aim to spend no more than $150,000 on the remodel. This principle helps ensure you do not over-improve the property relative to the neighborhood, which can make it difficult to recoup your investment upon resale. For a more detailed breakdown of budgeting and planning, we recommend reading our article Remodeling Your Kitchen: What You Need To Know. At Gadi Construction, we always advise clients to balance personal taste with long-term financial sense.
Adding 1000 square feet to your home is a significant project, and costs can vary widely based on the complexity of the design and the quality of finishes. For a project of this size in the Santa Clara and San Jose area, you should generally budget between $300 and $500 per square foot. This means a total cost ranging from $300,000 to $500,000 or more. This estimate typically covers foundation, framing, roofing, basic electrical and plumbing, and standard interior finishes. However, factors like site preparation, foundation type, custom cabinetry, and high-end flooring can push costs higher. For a detailed cost comparison between building from scratch versus using a prefabricated unit, we recommend reading our internal article titled Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. At Gadi Construction, we always advise getting a thorough site evaluation to identify any unique challenges before finalizing your budget.
When communicating with your contractor, avoid saying "I can get materials cheaper myself" as it disrupts supply chain responsibility. Also, do not say "Just do it quickly" as it pressures quality. Avoid revealing your maximum budget, as it removes negotiation leverage. Never say "I’ll handle the permits" unless you are licensed, as this creates legal liability. Instead, maintain transparent communication. For professional guidance, refer to our internal article How To Work With Contractors: A Practical Guide For Homeowners. Gadi Construction recommends focusing on clear scope and trust.
