Whether you're expanding a restaurant patio, building a rooftop deck, or creating a foot-traffic-friendly outdoor space, we’ve got you covered. Our team builds commercial-grade decks that meet Washington code, hold up to daily use, and elevate the look and function of your property.
We understand the demands of business use — and we build to meet them. That means strong framing, durable surfacing, ADA-compliant access, and safe exits. We coordinate with architects and property managers to build decks that look great and perform under pressure.
Elevated, rooftop, and ground-level builds
Drainage, fire-rating, and load planning included
Framing for bar rails, seating zones, and lighting

For restaurants, breweries, wineries, and event venues, a well-built deck adds real value. We design for customer flow, furniture zones, and safety — with materials that last through every season. Whether you're seating guests or hosting events, your deck will support your business goals.

Commercial decks require serious structure — often with higher loads, waterproofing needs, or fire resistance. We use pressure-treated framing, hardware that handles crowds, and surfacing that stands up to sun, rain, and spills. Rooftop? Side lot? Second story? We’ve built them all.
Commercial projects come with extra red tape — and we’re ready for it. We submit engineered plans, pull the right permits, and meet with inspectors so you don’t have to. Whether you're under city regulations or dealing with a tight downtown footprint, we keep your build compliant and on schedule.

Engineered for Heavy Use: We build framing systems designed for weight, movement, and wear.
Code-Compliant Every Time: ADA access, stair specs, railing height — all built to local code.
Built for Wet Weather: Water-shedding systems and slip-rated decking keep your guests safe.
Commercial-Grade Railings: Cable, metal, glass, or composite options that meet public use standards.
Scalable for Growth: Expand your deck later — we design for future phases if needed.
Don't worry, we can help!
From raised platforms for musicians to tucked-away storage under the deck, we build commercial spaces that support service and operations. Want built-in seating, host stands, or planter boxes? Done. We make sure your outdoor area works as hard as your team does.

You don’t need to juggle a designer, framer, permit tech, and inspector. We do it all — with one contract, one price, and one point of contact. From layout to inspection, we’re here to keep your commercial deck build simple, on time, and on budget.
Building a deck for public or commercial use brings smart questions — and we’re ready with straight answers.
Yes — we assess the load limits, waterproofing, and structural tie-ins before framing.
Composite is a top pick for its durability, stain resistance, and low maintenance.
Absolutely. We handle everything from ramp slope to railing height and exit planning.
Not always. We schedule work to limit disruption and maintain safe access when possible.
