One of the most common questions we hear from Seattle homeowners is: How long does the landscape design process take? While it would be great to offer a one-size-fits-all answer, the truth is that the timeline depends on a range of factors, including the size and complexity of the project, the clarity of your vision, and how many revisions are needed along the way.

Most landscape design projects in Seattle take between 4 and 6 weeks to complete. Smaller, clearly defined projects may take as little as 1–2 weeks, while larger or more customized designs can extend beyond 6 weeks depending on revisions, permitting, and complexity.

At Seattle Sustainable Landscapes (SSL), we prioritize thoughtful, well-paced design that delivers long-term satisfaction. Here’s what to expect.

The Typical Timeline: 4–6 Weeks

Most of our landscape design projects fall within a 4 to 6-week window from initial scoping to completed design. This includes:

  • Our initial site visit and visioning session
  • Design development and drafting of concept plans
  • Material research and selections
  • Revisions and budgeting adjustments based on your feedback

This timeline allows for creative exploration, practical refinement, and detailed documentation—all essential for a successful build.

What Can Speed Up the Landscape Design Process? (1–3 Weeks)

Some projects move more quickly, particularly if:

  • The project is relatively small or straightforward
  • You have a clear vision and quick decision-making process
  • Fewer revisions are needed
  • We’re working within a tight but clearly defined scope

In these cases, we can sometimes deliver a complete design in as little as 1–2 weeks. Our design team is highly responsive, especially when the path forward is well-defined.

What Can Extend a Landscape Design Timeline? (6+ Weeks)

On the other end of the spectrum, some design processes extend over several months. This is more common if:

Larger properties or highly customized installations like outdoor kitchens, custom structures, or multi-phase builds tend to need more time for planning and coordination.

Client Decision-Making & Availability

One of the biggest factors in timeline is you, homeowner. Your availability for meetings, speed of feedback, and level of decisiveness all influence how quickly we can move forward. Some clients enjoy a more extended collaborative process; others prefer to make fast decisions and move quickly into construction.

At SSL, we adapt to your pace while keeping the project moving forward efficiently.

What Happens After the Design Is Complete?

Once that the client approves the final design, we move into pre-construction planning. This includes:

  • Finalizing material selections
  • Scheduling your project based on our construction calendar
  • Ordering materials or specialty items

Our team ensures that your design is not only beautiful on paper, but ready for a smooth and timely installation.
