Landscape Design in Napa, CA From Sketch to Finished Yard

Keystone Yards takes your landscape design in Napa, CA from that first sketch all the way to a finished yard, without handing you off to a different contractor once construction starts. One team handles design, carpentry, masonry, landscaping, lighting, and irrigation, backed by a 2-year workmanship guarantee.

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.

Keystone Yards carpentry covers decks, pergolas, fences, gazebos, and trellises. Everything is built to hold up through Napa's hot summers and wet winters, using materials suited to this climate. We handle anything outside the home, except swimming pools.

Our masonry service includes pavers, fire pits, outdoor kitchens, water features, and stonework for patios, walkways, and retaining walls. We work on projects of any size across all three counties, and masonry work tends to book up fastest between December and March.

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.

— Process

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.

Planning

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.

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:

— WARRANTY

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.
