A multi-level deck isn’t just bigger—it’s smarter. It lets you break up outdoor zones for different uses: a grilling station on one tier, a hot tub on another, and dining or relaxing areas with their own space and views. We evaluate your home’s elevation, entry points, grade, and landscaping to create a layout that feels natural. Our designers plan each level with flow, function, and safety in mind—so it looks great and works even better.
Multi-level decks demand precision framing and strong support systems. We build ours to handle Wisconsin’s freeze-thaw cycles, snow loads, and shifting ground. Our team uses heavy-duty posts, double beams, and proper flashing to keep every level secure. We also include stair landings, railings, and lighting options that make every tier safe and accessible—day or night, rain or shine.

Multi-level decks give you the space to create distinct outdoor zones—and we help bring those ideas to life. Whether you want a shaded lounge under a pergola, a sunny grilling station with built-in counters, or a top-level retreat with privacy screens and views, our team designs every tier to serve a purpose. We offer custom stairs, deck skirting, under-deck storage, lighting, seating, and more—all tailored to your space.

We build tiered decks using pressure-treated wood, cedar, or composite decking—based on your preferences and performance goals. Composite is great for upper levels with exposure to sun and water, while cedar or treated lumber works well for shaded lower levels. Our team helps you mix and match materials for looks, function, and budget. No matter what you choose, we use weather-rated hardware, moisture barriers, and professional sealing to protect every tier.
From your first consultation to the final walkthrough, we manage everything. Multi-level decks require careful planning, code approvals, and coordination with your existing structure or landscaping. Our team handles all of it—including design, materials, engineering, permits, and construction. Whether it’s a full backyard transformation or an addition to an existing structure, we’ll make sure it’s done right, on time, and on budget
