Landscape Design & Installation in Seattle

Most disappointing Seattle gardens are not badly built — they are built in the wrong order by people who were never in the room together. A patio poured before anyone established where the water went. Planting installed before the wall that later had to be dug in behind it. Lighting added last and trenched through both. On this ground that sequencing problem is more expensive than elsewhere, because the buried work matters more: glacial till that will not drain, 38 inches of rain concentrated into six months, and lots where a machine may not physically reach the back garden. Designing the whole property first costs less than any one of those mistakes.

What we get called about

Landscape Design problems specific to Seattle.

Seattle takes 38+ inches of rain a year and almost all of it arrives October to March. That single fact decides more landscaping outcomes here than plant choice ever does — a patio without a drainage plan is a patio that heaves, and a lawn on undisturbed till is a lawn that sits under water all winter.

  • A garden landscaped piecemeal over years that now reads as three unrelated ideas
  • Planting installed before drainage, now sitting in ground that holds water
  • A design drawn by someone who never checked whether a machine could reach the site
  • A city lot where the usable space is far smaller than the lot size suggests
  • Repeated planting failures because the scheme ignored how little light the garden gets

Worth knowing in Seattle

Book design and estimating in January or February. By April the good crews in this city are committed for the season, and a design produced in winter has time to resolve permits, ECA checks and material lead times before the build window opens in March.

The order that saves money on a Seattle lot

On a phased project the sequence matters more than the timing, and getting it wrong is the most expensive avoidable mistake in residential landscaping here.

Everything buried goes in first: drainage, irrigation sleeves under any hard surface, conduit for lighting. While the ground is open and a machine is on site, these cost very little. Once there is a finished patio, a turf lawn and mature planting above them, the same work means excavating through everything you have already paid for. Empty conduit is close to free at stage one and is the single best insurance a phased garden can buy.

Structural work comes next — clearing, grade, walls, terracing — because everything above depends on the levels being right and nothing above can be installed twice. Then surfaces. Then planting and lighting last, when there is no more machinery coming through.

It is the least satisfying way to spend a first-phase budget: at the end of stage one on a Seattle hillside lot you may have a drain, a wall and bare ground. It is also the only sequence in which you pay for each piece of the garden once.

The method

How we build landscape design, wherever the job is.

The sequence does not change between neighbourhoods — what changes is the ground it is applied to. Full detail on the landscape design service page.

  1. 01

    Walk the property and listen

    What you want to use it for, who else uses it, what you hate about it now. Most of the useful information comes out of the second half of that conversation.

  2. 02

    Read the ground

    Grade, drainage, soil, existing trees and where a machine can get in. This is the half of design that never appears in a photograph and decides most of what is possible.

  3. 03

    Lay out zones before details

    Where the paved area goes, how big it really needs to be, what the route through the garden is. Getting these wrong cannot be fixed with better planting.

  4. 04

    Specify materials and price it

    Real products, real quantities, and a fixed written price with the assumptions stated so you can see what is included.

  5. 05

    Build in the right sequence

    Clearing, drainage, structural, surfaces, irrigation and lighting sleeves, then planting and finishes. The order is the difference between a build and a rework.

What it costs in Seattle

$8,000–$70,000 for a full design and installation

A full Seattle design and installation typically runs $8,000 to $70,000, and the spread is mostly structural work rather than planting. A flat lot with reasonable access needing surfaces, beds and lighting sits at the bottom. A sloped city lot needing drainage and retaining before anything visible can be built sits at the top. Design-only engagements are priced separately and credited against the build.

  • No down payment

    You pay after the project is fully completed.

  • Fixed price, agreed up front

    The estimate you sign is the price you pay.

  • 0% interest for up to 6 months

    Spread the cost with no interest.

  • Warranty on hardscaping

    Covers hardscape work; vegetation excluded.

Local questions

Landscape Design in Seattle, answered.

General questions about this service are on the service page. These are the ones that only come up here.

What does a Seattle landscape design actually produce?

A layout you can build from and price against: zones and levels set out, surfaces and materials specified, planting areas defined with species suited to each aspect, and the buried work — drainage runs, irrigation sleeves, lighting conduit — positioned before anything covers them. It is a working document rather than an artist's impression. Where a rendering helps you picture a specific area we will produce one, but what decides whether you like the finished garden is the dimensions and the levels, not the illustration.

How much of a Seattle garden should be lawn?

Less than most people assume, and the reason is climate rather than fashion. A lawn here is shaded for much of the day on a typical city lot, wet from October to April, and worn through wherever people walk. Under roughly 400 square feet it rarely thrives and always looks tired. The gardens that work in this city tend to hold a smaller, well-drained lawn or turf area with a genuine purpose, more paved surface than instinct suggests, and planting deep enough to give the boundary structure. That is a recommendation rather than a rule — if you want a big lawn we will build one that drains.

Can I do the design now and build it over several years?

Yes, and for a lot of budgets it is the sensible route — with one non-negotiable rule. Everything buried goes in during the first stage, because retrofitting drainage, irrigation sleeves or lighting conduit means excavating through work you have already paid for. Beyond that, staging follows structure first: clearing, grade and walls in year one, surfaces in year two, planting and lighting in year three. We plan it that way from the outset rather than pretending a phased build is the same as a full one, because the phasing changes the design decisions.

Do you plant as well, or only build the hard landscaping?

Both, and the planting is specified rather than decorated. Plants get chosen for the aspect, soil and exposure of the specific spot — a west-facing West Seattle bed and a shaded north-facing Capitol Hill side return want almost nothing in common. Worth knowing where the warranty sits: hardscape work is covered, vegetation is excluded, because whether a plant lives depends on watering and conditions after we leave. We will tell you what each planting needs to survive its first two summers, and we would rather specify something that lives than something that photographs well in June.
