A custom deck gives you solid ground where your yard needs it most. It turns uneven or soft areas into spaces for sitting, walking, or setting down what you’re carrying. A well-built deck connects your home and yard without feeling added on.
Onyx Landscape builds custom decks in Portland, OR and nearby areas. We walk the site with you, plan around your layout, and choose materials that hold up in wet seasons and dry spells. We shape every project around how you actually use your space.
Deck Construction Services from Onyx Landscape
We don’t force standard templates onto real yards. Every deck starts with a blank slate and a walk-through.
Ground-level decks:
These sit low and give a clean step down from the back door. Ideal for flat lots and smaller homes.
Raised decks:
For walkouts, sloped grades, or uneven ground. We manage footings, framing, and code requirements from start to finish.
Multi-level decks:
Split the layout into zones for grilling, planting, or relaxing. This layout gives you access to every part of your slope without building up walls.
Composite boards:
Low-maintenance, moisture-resistant, and clean underfoot. Good choice if you want less upkeep year to year.
Wood options:
Natural and strong. We finish every board to stand up to wet seasons and prevent early breakdown.


Benefits of Adding a Custom Deck to Your Property
A custom deck gives you a solid, defined surface you can use every day. It adds value to your property, creates space for gathering, and makes the yard easier to navigate. When it’s built with the right layout and materials, it becomes part of how you live outside.
- Increased property value: A custom deck makes your home more attractive to buyers. It shows that the outdoor space is finished, useful, and built to last.
- Room to entertain: A deck gives you a defined surface for meals, small gatherings, or relaxing with friends. You’re not relying on lawn chairs set in uneven grass.
- Better indoor-outdoor flow: A deck built level with your door makes the yard easier to access. It turns outdoor space into something you’ll use every day.
- Year-round use: Decks stay cleaner and more accessible through rain and colder months. With a cover or heater, you can keep using the space long after summer ends.
