Custom Deck Building in Seattle

A custom deck is one of the highest-return investments a Seattle homeowner can make. It adds livable square footage, creates a dedicated space for outdoor entertaining, and significantly increases property value — all while transforming how you experience your own backyard.

Whether you're envisioning a sweeping multi-level deck with built-in seating, a sleek low-profile composite platform off your kitchen, or a hardwood entertaining terrace with integrated lighting, Outdoor Oasis designs and builds decks that are tailored entirely to you.

How Seattle Homeowners Use a Custom Deck

A well-designed deck isn't a single-use space — it's a platform for the life you want to live outdoors. Here's how our clients put their custom decks to work:

  • Outdoor entertaining and hosting — A properly designed deck becomes your go-to venue for gatherings, dinners, and summer parties. With built-in seating, lighting, and defined zones, guests flow naturally from inside to out.

  • Alfresco dining — Seattle's long summer evenings are made for eating outside. Clients frequently design their decks around a dedicated dining area positioned to capture the best light or views.

  • Morning coffee and daily relaxation — Many homeowners tell us their favorite use of their new deck is the simplest one: a quiet morning with coffee and a view of their garden.

  • Kids' play and family space — A deck creates a safe, elevated space that's easy to supervise and easy to keep clean — perfect for young families who want outdoor space that's practical and enjoyable.

  • Home office overflow and creative space — With Seattle's mild summer climate, a covered deck becomes a genuine outdoor workspace or studio.

  • Hot tub and spa integration — Custom deck platforms designed specifically for hot tub installation are one of our most popular requests, adding luxury and resale value in equal measure.

  • Container gardening and planting — Raised deck surfaces and integrated planter boxes make it easy to grow herbs, flowers, or vegetables even on urban lots with limited ground space.

Decking Materials We Work With

We work with a curated range of premium decking materials and guide every client toward the option that best fits their aesthetic, maintenance preferences, and budget:

  • Composite decking — Low-maintenance, moisture-resistant, and available in a wide range of finishes. Ideal for Seattle's wet climate and high-traffic decks.

  • PVC decking — Fully waterproof and exceptionally durable, with a clean, modern appearance. A top choice for covered decks and rooftop applications.

  • Hardwood decking (Ipe, Tigerwood, Cedar) — Rich, natural warmth and character that no manufactured product can replicate. Properly sealed hardwood holds up beautifully in the Pacific Northwest.

  • Bamboo decking — A sustainable, hardwearing option with a distinctive, refined look increasingly popular among Seattle homeowners.

  • Premium Sustainable Decking Alternatives — Accoya wood, thermally modified wood, and Kebony wood decking provide the elegant beauty of natural wood without the eco-sustainability issues associated with other natural decking. The project displayed below is made almost completely out of thermally modified wood.

“We were delighted with the outcomes of Soren's work and thoroughly enjoyed collaborating with him. He meticulously designed and executed a remodel for our townhouse backyard, incorporating a new fence, deck, paved path, planters, outdoor furniture, and lighting. Soren consistently presented innovative and tasteful ideas and was receptive to feedback, allowing us to adapt them to our preferences. He coordinated the entire execution, including subcontractors, and undertook a significant portion of the work himself, including the stunning benches. All along he had a rigurous attention to detail. Perhaps most importantly, he remained open to learning about new products and techniques. The result was a top-quality project that has absolutely elevated our living space and received compliments from everyone, including friends, neighbors, and even other contractors who worked on it. It's rare to find someone so passionate about their craft, and we highly recommend Soren for any project.”

“Great experience from start to finish. I love Soren's attention to detail, and that made for both a smooth experience throughout construction and a final product that exceeded our expectations. What was once a dismal space has become a beautiful centerpiece of our home. Can't recommend highly enough, thank you!”
