Farnsworth Builders Construction
We’re a close-knit, family-run company with a strong foundation of long-standing team members. Siblings Wes Farnsworth (CEO) and Erin Farnsworth (Business Development) lead the company alongside Nicole Farnsworth (CFO) and Matt Testa (Operations Manager). Each of us brings a rich background—personally and professionally—which fuels our commitment to running this business with integrity, focus, and precision. Meeting deadlines, staying on budget, and getting every detail right is our top priority.
We specialize in building custom luxury homes that combine distinctive craftsmanship with smart, future-ready infrastructure—homes designed to stand the test of time and serve generations to come.
With a dedicated in-house team, we self-perform many of the trades to maintain strict quality control and keep projects on schedule. We also design and install our own solar systems, integrating them directly into the home's infrastructure—not as an afterthought or subcontracted element, but as a seamless part of the build.
