Tiered Deck Designs for Any Lot or Layout
Multi-level decks are perfect for uneven ground, walkout basements, or homes with elevated main floors. We design each level to serve a purpose—dining area above, lounge space below, stairs to the yard, or landings that connect to a patio or pool. Our structures are engineered to handle weight, weather, and traffic. No matter the slope or height, we make sure every level is usable, beautiful, and safe.
Multi-level decks demand more than great design—they require precise engineering. We use deep-set footings, doubled beams, and correctly spaced posts to support weight across multiple platforms. Our construction meets or exceeds North Carolina’s residential deck code, including railing heights, stair width, and landing transitions. You’ll get a deck that not only looks incredible—it performs safely for years.

We tailor each project to your home’s layout and property line. Need a walkout deck from a second story in Cary? Want a shaded lower patio beneath an elevated dining deck in Durham? We handle it. Our team maps every level, step, and support detail so it all flows—no awkward transitions or wasted space. We also account for zoning, HOA rules, and drainage concerns that affect multi-level projects.

Elevated decks face more sun, rain, and wind exposure, so choosing the right material matters. We install composite for ultra-low maintenance, cedar for classic style, or pressure-treated lumber for value and strength. Each is installed with corrosion-resistant hardware and sealed connection points. Your deck will not only handle the height—it’ll resist the weather, too.
Your deck should support how you actually live. We design multi-level systems with zones for grilling, dining, lounging, or hot tubs—each with the right structural support. Need storage or dry space underneath? We build in waterproofing and underdeck drainage systems. Need lighting or privacy screens? We can integrate those too. Our decks aren't just stacked—they're smart, functional spaces.

We’ve completed multi-tiered decks in mountain neighborhoods, coastal homes, and busy suburban lots. Every job teaches us more about how to build decks that look great—and perform on difficult terrain. From Durham hillsides to Gastonia backyards, we bring local knowledge to every slope, material, and code nuance. No lot is too tricky.
Considering a multi-level deck? Here are the questions NC homeowners ask most about these custom outdoor builds.
Does a multi-level deck require a permit in North Carolina?
Yes, and we handle it. These builds must meet stair, railing, and load codes—permits are required.
Can you build a second-story deck over a patio or porch?
Absolutely. We often design elevated decks with dry space, lighting, or lounging areas below.
What materials work best for multi-level decks?
Composite, cedar, and pressure-treated lumber are all options—depending on exposure and budget.
Do multi-level decks cost more than single-level builds?
Yes, due to complexity and materials. But they also add more usable space and value.
