You can trust us to listen to your ideas, understand your goals, and create (and install) a stunning garden that exceeds your expectations.

Garden Design Services

Here are some of the things that you can include in your garden design:

Plants

From lush Ornamental Shrubs and perennials for pollinators to native Oregon Grape and Vine Maples we’ll help you choose the best plants for your space. We provide expert advice on selecting the right native plants for our climate to ensure a thriving garden.

Retaining Walls

Transform your outdoor space with a retaining wall that combines style and functionality. This hardscaping feature not only enhances the visual appeal of your landscape but also adds lasting value and practical benefits.

Pathways and Patios

A garden is meant to be enjoyed. Let us create beautiful paver pathways and patios, allowing you to walk through and fully experience the beauty of your outdoor space.

Rain Gardens

A rain garden is a must here in the rainy Pacific Northwest. It helps filter rainwater and runoff while enhancing the beauty of your yard. A great eco-friendly choice!

Eco Lawns

For a sustainable lawn option, consider an eco lawn. It uses less water, fertilizer, and chemicals, requires minimal maintenance, and pairs perfectly with native plants.

Our Design Process

Garden Design Made Easy – From Concept to Completion

Initial Design Consultation

We begin with an initial design consultation, during which we take the time to understand your vision and goals for your garden!

Concept Drawings

Based on our consultation, we’ll then create 2-3 concept drawings, which serve as the foundation for your design plan.

Preliminary Design Plan

We’ll work closely with you to make any necessary revisions to the concept drawings and create a preliminary design plan that includes your plant selection list.

Masterplan Drawing

Finally, we deliver your finalized masterplan—a comprehensive blueprint of your new garden.

Now, Onto The Installation

Installation Proposal

Once the design is done, we’ll present a proposal for the installation.

Work Begins

Once you approve the process, we will kick off the installation process.

Final Walkthrough

Our job isn’t complete until you’re in love with your new space. That’s why we conduct a final walkthrough to ensure your satisfaction and address any loose ends.

What Sets Our Landscape Designs Apart

Life Like 3D Renderings

Having 3D garden design renderings in place before starting your project helps you visualize the end result. Whether you’re envisioning a new walkway adorned with vibrant perennials, a rain garden, or an eco lawn, these renderings allow you to see how our plans will come to life, ensuring the final design matches your vision perfectly.

Hands-On Approach

Brian takes a hands-on approach, working closely with clients throughout the entire design and installation process. They actively seek feedback and input and maintain clear communication in order to make you feel heard and ensure there are no surprises.

Custom Designs

Everyone has unique tastes when it comes to plants, vegetation, and greenery. After all, each person envisions a different look and feel for their home, with distinct aesthetic preferences.
