If you have ever searched "how much does landscaping cost" and gotten a frustratingly vague answer, you are not alone. Most homeowners in the Seattle area find that pricing depends on far more than yard size. Labor costs, slope, soil conditions, permit requirements, and the complexity of your design plan all play a role. At Angkorscape, we have worked on landscaping projects ranging from clean residential installs to full outdoor living transformations. This guide gives you real numbers to work with so you can budget before your first consultation.
Landscaping cost in Greater Seattle varies depending on project scope, yard size, and how many hardscaping features, plants, and structures are involved. Simple projects with basic plantings and mulch typically sit at the lower end of the range. Full design and build projects with patios, retaining walls, outdoor kitchens, and lighting run significantly higher.
Cost ranges are based on Angkorscape's real project history in Greater Seattle. Final pricing depends on site conditions, materials, and project scope.
💡 Pro Tip: Get your design plan completed before asking for contractor bids. A detailed plan means apples-to-apples quotes and far fewer surprises once construction starts.
The cost of a landscape master plan covers the design work that happens before any construction begins. Landscape design costs typically range from $2 to $8 per square foot, and design is one of several professional landscaping services homeowners may hire before installation. This includes a site assessment, design concepts, planting plans, and construction documents that your contractor uses to build the project.
The cost of a landscape master plan generally scales with property size and complexity. A focused backyard plan costs less than a full property design, and if a licensed landscape architect is involved, labor rates are usually higher than those of general lawn crews. You can learn more about how this process works on our landscape design process page.
Many homeowners ask about 3D landscape design cost as a separate line item. Some designers include 3D renderings in their base fee. Others offer them as an add-on, for example when a homeowner wants a more detailed preview beyond the standard plan. The cost of 2D and 3D landscape renderings varies by designer, but 3D visuals can help homeowners determine whether the layout feels right before any money is spent on materials or labor.
So what actually makes one project cost more than another? Several factors push landscaping cost higher, and understanding them helps you prioritize.
Before your first meeting, walk your yard and make notes on these factors. This helps your designer scope the project accurately.
Paver patio cost is one of the most common questions we hear. The total depends on the patio size, the type of paver selected, and how much site prep is needed. For a typical patio installation, homeowners can expect to pay $2,000 to $5,800, with larger areas and heavier site prep pushing costs higher.
Our completed projects portfolio shows a range of patio styles at different budget levels so you can see what is possible before you decide.
Retaining walls are one of the most variable line items in any landscaping project. A simple decorative garden wall costs far less than a structural wall designed to hold back significant soil on a sloped property. Costs also shift based on height, drainage needs, access, and materials such as timber, concrete block, stone, and other materials. If your wall exceeds local permit thresholds, expect additional review time and cost.
Permit requirements vary by city and county in the Greater Seattle area. Always check with your local municipality if your wall exceeds a certain height.
Landscape drainage cost is often overlooked during initial planning. But in Seattle, proper drainage is not optional. The region's rainfall and clay-heavy soils make drainage a structural necessity.
The cost to install landscape lighting depends on the number of fixtures, the type of system, and how much trenching or wiring is required.
A typical landscape lighting cost ranges from a few hundred dollars for a basic setup to several thousand for a more advanced system with added fixtures, effects, and controls.
The cost to install low voltage landscape lighting is generally more accessible for most homeowners. It is also easier to expand over time. A professionally designed lighting plan accounts for fixture placement, transformer load, and how outdoor lights interact with plants as they grow.
💡 Pro Tip: Plan your landscape lighting during the design phase, not after installation. Running conduit during construction costs far less than trenching through a finished yard later.
Outdoor fireplace cost covers materials, construction, gas line work if applicable, and any structural footing requirements. Fire features range from built-in wood-burning fireplaces to gas fire pit tables.
New build landscaping cost tends to be lower when fire features are planned from the start. Retrofitting a gas fireplace into an existing landscape adds mobilization and trenching costs.
New build landscaping cost can be more predictable than renovation work because the site starts clean. There is no demolition, no removal of old hardscaping, and no guessing what is buried underground.
Many homeowners on new builds wait too long to hire a landscape designer. Industry professionals generally recommend engaging a designer before the exterior concrete is finished so drainage and access points can be coordinated with the builder.
Landscaping cost in Seattle is not one number. It is a combination of design fees, material selections, site conditions, and the scope of work you choose to take on. The most effective way to control your budget is to start with a solid plan and understand what each element costs before construction starts. Whether your project is a simple backyard refresh or a complete outdoor living transformation, the right design partner makes a real difference.

Landscaping cost for a full design and build project in Greater Seattle varies based on yard size, materials, and scope. Projects range from mid-range installs to premium outdoor living spaces, and the best way to get an accurate number is through a detailed site assessment and design plan.
A landscape master plan fee typically covers site analysis, 2D drawings, planting plans, hardscaping layouts, and construction documents. Some designers also include 3D landscape design cost as part of their package or as an optional add-on. Low cost design options exist, but they may not include the same site-specific detail or build-ready documentation as a professional package.
Paver patio cost is most affected by paver type, site prep requirements, and patio size. Labor costs also increase when the site requires significant excavation or drainage work before installation can begin.
The cost to install landscape lighting depends on the number of fixtures, the system type, and how much electrical work is involved. The cost to install low voltage landscape lighting is generally lower and easier to expand than a full hardwired system.
Yes, landscape drainage cost varies based on soil type, yard slope, and how much water needs to be redirected. Seattle's heavy rainfall and clay soils often mean drainage is a required part of any serious landscaping project rather than an optional upgrade.
New build landscaping cost should be factored in before construction begins. Engaging a landscape designer early allows utilities, drainage, and access points to be coordinated with your builder, which reduces overall project costs.
