Maximize Outdoor Space with Style and Function

Multi-Level Deck Construction in Wisconsin

Smart Design for Complex Properties

Tiered Decks That Match Your Home’s Layout

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.

Built for Strength, Safety, and Year-Round Use

Engineered for Wisconsin Elevation and Weather

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.

  • Tiered stairs with landings and lighting

  • Code-compliant rails and guard heights

Custom Features for Every Level and Lifestyle

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.

Materials That Look Great and Perform

Wood and Composite Options for Multi-Level Builds

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.
