Grassi & Associates
At Grassi & Associates, we have been privileged to work with world-class architects and the most discerning of clients. Each of our projects has been a story to itself because there is no formula for what we do. We approach every project with open minds and this approach to building custom homes, estates, and select commercial projects keeps us engaged and innovative. We are craftsmen and builders who are also artists shunning the formulaic in favor of the innovative. We have an eye and a passion for fine work, and we have the skills to bring it to bear. We are interpreters and eternal optimists, taking an architect’s vision and a client’s dream and giving it a physical reality. We are relentless in our desire to take on new challenges, and we are hungry to learn more about the art we have chosen: building. But there is also an experienced practicality to our team at Grassi, and the foundation of that practicality is a commitment to “value.” Each of our employees at Grassi, some of whom have been with us since the beginning, understand that the key to a successful project is a healthy interplay between helping clients realize their dreams while ensuring that our clients get exceptional value for every dollar spent. Our team at Grassi & Associates has been building custom homes, estates, and select commercial projects in the Napa and Sonoma valleys for over two decades. We believe that the building process should be as custom as the home we are entrusted to build.
