Defined Spaces That Feel Open, Airy, and Inviting

Custom Shade Structures That Match Your Home and Landscape

Pergolas, gazebos, and arbors bring structure and elegance to your outdoor space.

From modern lines to classic scrollwork, we create lasting features that add value and comfort.

Open-Air Comfort With Architectural Detail

Shade Structures Built to Elevate Your Outdoor Living

Whether freestanding or attached, these structures provide visual interest and functional benefits—like light shade, hanging garden options, or cozy seating areas. We build with cedar, pressure-treated lumber, or powder-coated steel for long-term strength. Perfect for patios, garden paths, or deck upgrades, these features define space without closing it off.

Decorative or Functional—You Choose the Use

Some clients want climbing vines. Others want shade over a hot tub. Still others want to define a space for seating or fire pits. We help you plan a structure that not only fits the space, but also serves a clear purpose. Whether purely decorative or fully usable, each build is anchored, secured, and finished with care. From modern minimalist to rustic charm, we deliver the look you want.

Materials That Work With Weather and Style

We use cedar, pressure-treated pine, composite wraps, and metal framing—depending on the structure type and your preferences. Every component is selected for stability, weather resistance, and minimal upkeep. Need a retractable shade canopy, lighting, or a privacy screen? We can add that too. Each feature we build is both a focal point and a functional asset to your yard.

Upgrade Any Deck, Yard, or Garden Entry

Shade Features That Anchor Outdoor Design

These aren’t afterthoughts—they’re core elements of how your yard flows and feels. We build pergolas over existing decks, gazebos on concrete or gravel pads, and arbors that create inviting entry points. All structures are designed with scale, balance, and long-term durability in mind. They enhance usability and create a finished look that adds real curb appeal.

What to Expect When Adding a Shade Structure

We start by identifying where and how you’ll use the structure—shade over a deck, visual interest near a path, or a destination space in your yard. You’ll choose material, size, roof style, and any extras. Then we install cleanly, safely, and to code. From prep to finish, it’s a fast and dramatic upgrade.

Built-In Beauty With None of the Seasonal Hassle

Unlike flimsy kits or pop-up canopies, our pergolas, gazebos, and arbors are built with real framing, anchored footings, and long-lasting finishes. They don’t need to be taken down or stored for the winter. Just clean once a year, and they’re good to go. It’s a one-time investment that improves both form and function across every season.
