Montana landscapes offer sweeping views and sloped lots perfect conditions for a multi-level deck. These builds create natural zones for different uses: upper levels for cooking and dining, lower tiers for lounging or hot tubs, and mid-level landings for connecting entries or managing grade. Our decks are engineered for safety, drainage, and load-bearing performance across every level—so your outdoor living stays beautiful and secure from top to bottom.
Building a multi-tier deck means much more than stacking platforms. We start with detailed elevation planning, using laser levels and 3D modeling to design safe transitions between levels. Every landing, stair, and railing must meet code and still look seamless. We anchor each tier independently, ensuring stability and long-term performance. Whether your deck covers 200 or 2,000 square feet, we make sure every level serves a purpose and holds its value.

We design multi-level decks for every scenario walkout basements, raised ranch homes, sloped yards, and second-story living rooms. Need one level for grilling and another for soaking in the view? Done. Want a sun deck above and a covered patio below? We’ll build it. With Montana’s unique elevations and weather patterns, we make sure your structure looks great, drains properly, and functions year-round.

Multi-level decks require strategic load distribution and code-compliant framing. We calculate joist spans, footing depth, and stair loads based on your lot, elevation, and expected use. For larger or elevated builds, we often collaborate with structural engineers to guarantee long-term safety. We also add lateral bracing, reinforced beams, and blocking between levels to handle Montana’s wind and snow. It’s not just about looks—it’s about rock-solid performance.
From concept to completion, we manage every part of your multi-level deck project. Our team handles site measurement, custom design, city or county permitting, and final inspection. We help you select materials that work with both form and function composite, cedar, or pressure-treated. All stairs, landings, and guardrails meet Montana code and are installed by licensed professionals who specialize in large-scale builds.

Montana’s stunning landscapes require more than pretty decks—they need strong ones. We account for heavy snow load, high winds, slope pressure, and soil movement when building multi-level structures. From deep-set footings to wind bracing, we engineer for elevation. And with decades of experience across cities like Helena, Bozeman, and Kalispell, we know exactly what each area demands.
Here’s what Montana homeowners often ask when considering a multi-level deck project:

Almost always. We handle all permitting based on your location and scope.
