Plumas County General Contractor with a Deep Understanding of the Region

Custom home building across Grizzly Ranch, Whitehawk Ranch, Nakoma, and the Lost Sierra

At Williams Construction & Design Group, we specialize in building custom homes and commercial spaces that reflect the distinctive charm and natural beauty of The Lost Sierra. As an experienced Plumas County general contractor, we understand the area’s unique architectural styles, rural character, and the specific building codes and permitting processes that come with working in this diverse region.

Our team’s deep connection to the local culture and landscape allows us to create structures that feel both timeless and true to their surroundings. From secluded mountain cabins to thoughtfully designed community spaces, we approach each project with a commitment to craftsmanship, authenticity, and attention to detail—ensuring every build enhances the fabric of the Plumas County lifestyle.

Amenities & Custom Homes

COMMUNITY

Grizzly Ranch, Portola, CA

OUR WORK

Lake House, Recreation Center, Sales Center, covered bridge, and several custom homes

Grizzly Ranch is one of the Lost Sierra's premier gated communities, and building here means understanding the low-density, nature-first character it was founded on. Williams Construction is also among the approved custom home builders featured on Grizzly Ranch's official builder list, and we work with homeowners throughout the community on new construction and remodels. 

Williams Construction has been part of that landscape, having built the community's Lake House, recreation center, sales center, and a custom-designed covered bridge – work that reflects the natural materials and mountain style Grizzly Ranch is known for.

Custom Home Build: The Bolt House

COMMUNITY

Grizzly Ranch, Plumas County, CA

OUR WORK

A fully custom, historically accurate log cabin.

Known as "Zakopane in the Sierras," this home was built for a family who wanted a cabin that authentically reflected their Prussian, Scandinavian, and Nordic heritage — down to hand-carved details, reclaimed materials from twelve countries, and 500-year-old salvaged temple stone floors. It's been featured in Mountain Living and Log Home Living, and stands as one of the most detailed custom builds Williams Construction has completed in Plumas County.

Whitehawk Ranch, Plumas County, CA

OUR WORK

Founders’ residence, plus additional client homes.

Whitehawk Ranch holds a special place for our team. It is where our founders settled 20 years ago when moving from Truckee, and where we’ve since built several additional homes for clients. We know Whitehawk’s terrain, architectural review process, and design language well.
