Each structure we build is tailored to your space and goals—shade, privacy, seating, or garden entry. We design pergolas for decks and patios, gazebos for freestanding lounging areas, and arbors for walkways or fencing transitions. Whether you want a simple post-and-beam structure or something ornate and architectural, we’ll help you choose the right size, materials, and placement.
Every pergola, gazebo, and arbor we build is reinforced to hold up under Wisconsin’s seasonal stresses—from snow loads to wind gusts. We use weather-rated wood and hardware, and anchor each structure securely for long-term durability. You’ll get more than a decorative accent—you’ll get a functional feature that adds real value to your property

Custom finishes, trim, and roofing add visual impact

A pergola or gazebo does more than add beauty—it creates a sense of place. Use it to anchor a seating area, define a dining space, or provide relief from direct sunlight. Arbors offer charming transitions between areas of your yard or serve as entry points to fenced zones or gardens. These features work as architectural accents and functional upgrades, with plenty of options to fit any aesthetic.

We don’t just build pretty structures—we build strong ones. Every post is set deep and anchored properly. Rafters are spaced for strength and symmetry. For gazebos, we offer open or screened designs, optional benches, and shingled or metal roofs. Pergolas can include angled slats, retractable canopies, or lighting. With decades of experience, we ensure everything looks clean and lasts through Wisconsin’s climate.
You don’t need to juggle contractors or guess on materials. We design each structure in-house and build it with our own crews. From layout sketches to footing depth and finish carpentry, we handle every detail. Want to match your home’s trim or coordinate with your deck stain? We’ll help you pick the right options. Our goal is a structure that fits perfectly and performs beautifully.
