One Team for Your Whole Outdoor Design Project
Keystone Yards offers full landscape design and build services for homeowners in Napa, Contra Costa, and Marin counties. We design your outdoor space, then build it ourselves: patios, decks, outdoor kitchens, fire pits, planting beds, and everything else that goes into a finished yard. Carpentry, masonry, planting, lighting, and irrigation are all handled in-house. You work with one team from the first sketch to the final walkthrough, instead of hiring separate contractors for each piece of the project and coordinating their schedules yourself.
Projects range from a single fire pit and seating area to a full backyard rebuild that touches every trade at once. Whichever end of that range your project falls on, the same crew handles the design, the construction, and everything in between, so nothing gets lost between a designer's plan and a builder's interpretation of it.
Landscaping from Keystone Yards covers planting, sod, grading, ponds, and site demolition. This is the phase that turns a finished construction site back into an actual yard, with irrigation and drainage worked in so everything you plant actually survives.
This is just a preview of everything we handle. Every yard is different, so the service you actually need might not be pictured here. See the full list of services in Napa, CA to find the right fit for your yard.

How Our Napa Design-Build Process Works
Every landscape design and build project with Keystone Yards follows the same five steps, from your first site visit to the final walkthrough:
01. Owen Walks Your Property
Every landscape design and build project with Keystone Yards follows the same five steps, from your first site visit to the final walkthrough:
02. You Get a Real Design
That includes 3D concepts and covers every phase of the work, from demolition through final planting, so you can see the finished yard before construction ever starts.
03. We Lock In Your Schedule
Once the design is approved, you get a clear timeline and payment plan up front, so you know exactly what to expect and when, instead of open-ended promises.
04. One Crew Builds Everything
Carpentry, masonry, landscaping, electrical, and plumbing happen in sequence, coordinated by the same crew instead of four separate trades working around each other's schedules.
05. We Walk the Finished Yard
Before we call it done, we point out anything you should know about upkeep, and your 2-year workmanship guarantee starts that same day.

Keystone Yards: Napa's Design-Build Company
Keystone Yards is owned and run by Owen Lynn, operating under Keystone Building Inc. We've provided landscape design and build services across Napa, Sonoma, Marin, Solano, and Contra Costa counties for 8 years, on projects ranging from small patio upgrades to full backyard transformations. Every project is handled in-house, from design through construction, without subcontracted crews. Read more about Owen and the Keystone Yards story.
Owen Lynn: On Site From Day One
Owen Lynn owns and runs Keystone Yards under Keystone Building Inc. He visits every site himself, writes every estimate personally, and stays on as your point of contact from the first conversation through the final walkthrough.
From Blueprint to Backyard
Every project starts as a 2D layout, then moves into a 3D rendering so you can see the design before anyone breaks ground. From there, our crew handles the site work: digging, grading, and building according to that plan. What's left once the dust settles is a polished, finished yard that matches exactly what you approved.
Every Project Gets a Real 3D Design
Every Keystone Yards project moves from a 2D plan into a real 3D design before construction starts, not just a rough sketch. These renders come from actual projects across Napa, Sonoma, Marin, Solano, and Contra Costa counties, so you can see the kind of detail that goes into planning a yard before anyone breaks ground.
Landscape Design Across Napa, Sonoma, Marin, Solano & Contra Costa
Keystone Yards offers landscape design and build services across five counties: Napa, Sonoma, Marin, Solano, and Contra Costa. A few of the cities we work in most often:
A 2-Year Guarantee on Every Landscape Project
Every landscape design and build project from Keystone Yards includes a 2-year workmanship guarantee in writing. If something we built has a problem within that window, whether it's a settling paver or a fence post that's come loose, we come back and fix it. That's the entire policy.
There's no separate claims process to navigate. You call, describe the problem, and Owen schedules a time to come look at it himself. Most issues get fixed on that same visit or scheduled for the next available slot, not routed through a call center or a different repair crew than the one who built it.
