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..

We design additions that complement your existing structure while updating your home with practical, modern features.

A wider living area gives you more room for gatherings, entertainment, and daily relaxation. This design increases comfort while keeping the open, bright feel families love.
Perfect for visiting relatives or multigenerational living, this suite includes a private bedroom, full bath, and optional kitchenette. It adds convenience while keeping everyone comfortable.
A kitchen bump-out adds more workspace, improved storage, and room for upgraded appliances. It creates a smoother cooking experience and a brighter, more inviting layout.
This addition offers a dedicated, distraction-free area for work or school. With organized storage and thoughtful lighting, it boosts productivity and provides a peaceful environment.
A sunroom lets natural light flow in, creating a warm and calm space for reading, hobbies, or coffee breaks. It blends indoor comfort with an airy, outdoor feel.

For a 20x20 addition, which totals 400 square feet, homeowners in the Santa Clara CA and San Jose CA area should expect costs to vary significantly based on scope. A basic, single-story room addition typically ranges from $200 to $350 per square foot for standard finishes, placing the total between $80,000 and $140,000. However, if the project involves a second story, complex foundation work, or high-end finishes, costs can exceed $450 per square foot. For a detailed breakdown of a similar high-end project, our internal article titled Monte Sereno Case Study: Second-Story Addition provides specific cost data and challenges faced in this region. Always factor in permit fees, engineering, and potential structural upgrades, as local codes in Santa Clara County are strict. A professional site evaluation is essential for an accurate estimate.
When communicating with your contractor, avoid saying phrases that can undermine trust or create misunderstandings. Never say "I can get this done cheaper elsewhere," as it suggests you do not value their expertise or pricing structure. Avoid vague statements like "Just do whatever you think is best" without clear approval, as this can lead to scope creep and unexpected costs. Do not ask for work to be done "off the books" or without permits, as this violates legal and safety standards. Instead, maintain open, respectful communication. For more guidance, refer to our internal article How To Work With Contractors: A Practical Guide For Homeowners, which provides practical advice on building a positive working relationship with your contractor.
Adding 1000 square feet to your home is a major renovation. In the Santa Clara and San Jose area, you can expect costs to range from $300 to $600 per square foot. This means a total project cost between $300,000 and $600,000. The wide range depends on the complexity of the design, foundation work, and the quality of finishes. For a project of this size, you must also budget for architectural plans, structural engineering, and city permit fees. To get a more accurate estimate, you should decide between a traditional stick-built addition and a prefabricated unit. For a detailed breakdown of these options, please refer to our internal article titled Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. Gadi Construction recommends getting at least three detailed bids from licensed contractors to compare scope and pricing before making a decision.
The 30% rule is a common financial guideline suggesting that homeowners should not spend more than 30% of their home's current value on a single renovation project. This principle helps ensure that your investment does not exceed the potential return when you sell the property. For example, if your home is worth $500,000, you would cap a major remodel at $150,000. However, this is a general benchmark, not a strict requirement. For a more tailored approach, especially in the Santa Clara CA and San Jose CA area, we recommend reviewing our internal article titled 'Budgeting For A Bathroom Renovation In The Bay Area' at Budgeting For A Bathroom Renovation In The Bay Area for localized insights. At Gadi Construction, we always advise balancing personal enjoyment with long-term property value.
