Meet Walter Wehrli.

Wehrli Construction, your premier choice for luxury custom homes in Contra Costa county, CA. I'm Walter. My passion is to create beautiful, functional homes that stand the test of time.

I used to design and manage high-tech data centers for the world's largest companies while maintaining a thriving woodworking hobby. My professional background enables me to approach each project with unmatched precision and attention to detail. While remodeling my own homes, I learned that many builders have shortcuts and make shortsighted decisions that lead to shoddy work. I could not accept that.

Thus, Wehrli Construction was born. People who pay for quality should get it. So, I studied residential construction closely, earned California General Contractor's License #848015, and started building how I believed it should be.  

My father immigrated from Switzerland and worked at the world-class Steinway & Sons Piano Company building pianos by hand. From an early age, he taught me to do the right thing the first time, be the best at it, and never take shortcuts.

Building or remodeling your home is a significant life event and investment. Building for longevity is at the heart of my philosophy. Like any other field, homebuilding is subject to fads that look fresh one year and tired the next. I don't chase fads. I focus on classically beautiful designs that stand the test of time and incorporate modern day-to-day livability, ensuring your home remains a source of comfort and joy for years.

I aim to make the process smooth, stress-free, and enjoyable for my clients. I am committed to working closely with you, your designer, and your architect to meticulously build a home that reflects your individuality and exceeds your expectations. That's why I am dedicated to crafting exquisite and functional homes constructed with the finest materials by the best craftsmen.

Unlike most builders who rely on generalists for a wide range of tasks, I have assembled a team of experienced specialists to deliver every aspect of your home. From electrical to plumbing to carpentry to sheetrock installation, my team of expert craftsmen is recognized as the best in their fields. I oversee every detail, from the color of the grout to drywall taping in the garage. I am on-site for every project to make sure we deliver the dream home you imagined.

I started this journey over 20 years ago. Here is some of the recognition I've earned along the way.
