Why the Bay Area Chooses Gadi Construction
I engaged GADI Constructions Inc to restore my unit in a high rise in San Jose. Right from the beginning Millie, Project Manager, was very professional and when entrusted with the job completed the repair and restoration work smoothly and in time with perfection with time to time progress reporting on phone and through video.
We explored a home addition for our growing family and these folks handled everything with a lot of thought. The builders explained the remodel plan clearly and made the space blend into the house naturally. It was a solid experience all around.
We recently engaged Gadi Construction for a home renovation project, and the experience exceeded our expectations. Their team demonstrated exceptional flexibility, efficiency, and accommodation, adapting seamlessly to our evolving needs while maintaining a high standard of workmanship. The quality of the final output was impressive, reflecting meticulous attention to detail. Millie, our dedicated project manager, along with her team including Mike, fostered a reassuring and collaborative environment throughout the process, ensuring clear communication and minimal disruption. We highly recommend Gadi Construction for any renovation endeavors; their professionalism and commitment to client satisfaction are commendable.

We worked with Nadav from Gadi Construction during the planning phase of our expansion project, and he was a fantastic advisor throughout the process. He helped us think through every detail — from design implications to quality considerations — and brought a thoughtful, thorough, and methodical approach to each discussion.
Nadav was always friendly, highly professional, and incredibly responsive. It consistently felt like he was acting as a truly independent advisor who cared deeply about building long-term relationships and making sure we would get the very best outcome for our project. His proposals were detailed, insightful, and clearly grounded in deep experience.
Although we ultimately moved forward with another contractor who came through a personal referral, that decision wasn’t a reflection on Nadav’s work or professionalism. Based on our experience, we’d be thrilled to work with him in the future and wholeheartedly recommend him to anyone looking for a trusted, high-quality construction partner.
I went with them for a kitchen makeover and it was worth every penny. The design team helped me see options I never thought about.
Their skilled builders were respectful of the house and kept everything tidy. It felt like a real partnership through the whole remodel.
The value added by the new layout is already noticeable. I still walk in and smile because the remodel turned out exactly right.
Taking on a whole house renovation sounded stressful but they took the edge off. They walked us through each stage of the project so we always knew what was happening. The result feels like a true custom home remodeling job.
The bathroom remodel completely changed how our space feels. Their team helped plan everything so the design made sense and looked great. The quality build is obvious in every corner. It’s nice to have a space that’s functional and adds value at the same time.
We worked with this business for a full residential remodel, and it was a great experience. The skilled builders brought the design to life exactly as we imagined. Every room feels intentional and high-quality. I’d happily recommend them to anyone looking for a thoughtful and professional remodel.

The cost of a 20x20 addition can vary widely based on location, materials, and complexity, but a general range is between $80,000 and $160,000. This translates to roughly $200 to $400 per square foot for a basic to mid-grade project. Key cost factors include the foundation work, roofing, siding, interior finishes, and whether plumbing or electrical systems are extended. A simple, single-room addition with standard finishes will be at the lower end, while a project involving a kitchen or bathroom, high-end materials, or complex architectural details will reach the higher end. It is crucial to obtain detailed quotes from licensed contractors, as site preparation, permits, and local labor rates significantly impact the final price.
The 30% rule in remodeling is a widely cited budgeting guideline suggesting that homeowners should not spend more than 30% of their home's current market value on a major renovation project. This rule helps maintain financial prudence, ensuring the investment does not vastly exceed the potential increase in the property's resale value. For example, on a $500,000 home, the recommended renovation budget would cap at approximately $150,000. This is a general benchmark to prevent over-improvement for the neighborhood, which can make it difficult to recoup costs. It is crucial to obtain detailed estimates, factor in a contingency of 10-20% for unexpected issues, and align the project scope with local market norms to protect your investment.
The most expensive part of a home addition is typically the structural work and foundation. This includes excavation, pouring a new concrete foundation or slab, and constructing the load-bearing framework. These elements are labor-intensive, require specialized materials, and must meet strict building codes, forming the project's non-negotiable core cost. Following this, complex trades like electrical, plumbing, and HVAC integration into the existing home systems also command significant expense. High-end finishes like custom cabinetry or specialty flooring are major cost drivers but are more variable. Ultimately, the foundational and structural phase is the largest fixed investment, as it dictates the safety, stability, and longevity of the entire addition.
The cost comparison between adding an addition (building out) versus building up (adding a second story) depends heavily on your specific project and existing structure. Generally, building out is often less expensive per square foot initially, as it avoids major structural modifications to the existing foundation and roof. However, it consumes yard space and may require extensive site work. Building up can be more cost-effective on a small lot and avoids foundation costs, but it typically requires a detailed structural analysis, potential reinforcement of the first-floor walls and foundation, and temporarily relocating occupants during construction. A professional assessment of your property's structural capacity, zoning laws, and your long-term needs is crucial for an accurate comparison and decision.
