If your backyard has a slope or elevation change, a multi-level deck can turn it into a functional outdoor showpiece. We design and build tiered decks that follow your landscape — creating zones for dining, relaxing, hot tubs, and more. Whether you want one stair flight or four levels, our team brings structure and flow to your outdoor space.
Multi-level decks are more than beautiful — they’re useful. We create spaces with purpose: upper levels for grilling, mid-levels for dining, lower levels for lounging or playing. Each tier has a reason, and we help you plan it around your routine, your furniture, and your family.
Designed for Washington’s slopes and view lots
Built-in stairs, landings, and safety railings
Multiple framing styles: cantilevered, supported, or freestanding

Building a multi-level deck isn’t just stacking boards — it takes planning, engineering, and precision. We dig deep footings, evaluate soil stability, and ensure each level is properly supported. We use safe step heights, wide landings, and strong hardware to keep everything secure. It looks seamless — because the structure underneath is solid.

Elevated and multi-level decks face more wear from weather and movement. That’s why we use pressure-treated framing, water-managed flashing, and premium deck boards. You can mix and match materials — cedar for one level, composite for another — or go with a unified look across every tier. Either way, we’ll guide you on what performs best.
Multi-level decks turn small or uneven yards into usable square footage. You gain new zones for grilling, dining, fire pits, or hot tubs — all without needing flat land. We design every level for specific uses, add lighting, and ensure smooth transitions between each tier. It’s the ideal setup for modern outdoor living in Washington.

Multi-level decks are a smart way to add value and space — but they raise a few smart questions. Here are our answers.
It depends on materials, number of levels, and access. Most are 20–40% more than single-level decks, but add significantly more usable space.
You need one permit for the full deck structure. We handle the entire process and ensure code compliance.
Yes. We specialize in building on difficult terrain, including steep or uneven ground.
Composite is popular due to durability, but pressure-treated framing and cedar can also work with proper care.
