We are Avalon Northwest. We create awesome spaces.

We offer landscape construction services within Seattle, with the mission of bringing the comfort you feel in your home into your outdoor spaces. We pride ourselves on our relationships with our clients and aim to make a potentially stressful process feel easy, fun and inspired.

Our specialty is working closely with local designers–in a variety of styles–to transform your property into a complete outdoor living space. From beginning to end, you will work with the same core crew. Kevin will be your contact on your project from consultation to final clean-up, and we will stick around until everything is perfect. If you aren’t satisfied, we aren’t satisfied.

We don’t just build landscapes, we build lasting relationships.

“In a nutshell, we are thrilled! Both of us are extremely picky and opinionated, but as soon as we met with Kevin he gave us the confidence we needed to hire Avalon for our project. He is a true professional in every sense of the word. His high standards, meticulous attention to detail, and expert consultation made us feel at ease throughout the process. He listened carefully to our needs and provided timely answers to all of our questions. It is obvious that everyone at Avalon shares a passion for what they do, the whole team was a pleasure to work with. A million thanks for the skillfully executed workmanship and the good karma throughout the process.”
“I never imagined I would be moved to thank the contractors of my neighbors — but I´ve gotta say thanks all the same. Your whole team was friendly, and considerate of the neighbors….Thanks for being excellent contractors in a world that will tolerate a lot of mediocre values. You are great, and I’m very impressed with the work you’ve done next door, and the considerate nature in how you did it!”
“Kevin created a beautiful oasis for our family which we admire and enjoy everyday. Thanks Kevin and Avalon!”

“Everyone was great to work with. Great crew! Fine workmanship and willingness to go the extra mile to meet our whims. Thanks!”
“Kevin, thanks so much for all you and Avalon have done–your workmanship is only surpassed by your integrity! You have a couple of fans who will do all we can to let people know what a great company you are part of. We LOVE our new porch and walkway!”
