Built for Beauty and Durability
Our pergolas and gazebos are more than shade structures—they’re long-term outdoor investments. Each design is engineered to resist wind, snow, and temperature swings common across the northern plains. We use premium cedar, pressure-treated wood, or maintenance-free vinyl, depending on your design goals and budget. Every project is built to code, ensuring safe, durable structures that elevate your outdoor living space.
Whether you’re adding a small garden arbor or a full-size gazebo for entertaining, we tailor every project to your needs. Our designers work closely with you to determine ideal placement, materials, and roof styles. Each structure enhances your home’s exterior while offering functional shade and relaxation space.

Every pergola, gazebo, and arbor we build starts with solid footings and reinforced framing. We design for snow loads, drainage, and wind resistance, using galvanized hardware and corrosion-proof fasteners. Our finishing touches include UV-resistant stains and protective coatings to preserve natural wood tones. The result: structures that look elegant year after year, no matter what North Dakota’s weather brings.

From harsh winters to humid summers, our outdoor structures are made to last. We engineer each pergola, gazebo, and arbor with materials that resist warping, cracking, and corrosion. Roofed gazebos provide full coverage from snow and sun, while open-beam pergolas add shade without blocking airflow. With proper drainage, anchoring, and waterproofing, your structure will stay stable and beautiful year after year.
Every pergola or gazebo is designed to complement your home’s architecture. Whether you prefer rustic cedar beams, painted white vinyl, or sleek modern composite finishes, we’ll create a design that fits your vision. Add lighting, built-in benches, or climbing vines for a personalized touch. Our structures aren’t just functional—they’re statement pieces that enhance your property’s beauty and value.
