Trellis or Pergola?
How to Choose the Right Shade Structure for Your Bay Area Backyard?
If you’re planning to upgrade your Bay Area backyard, adding a shade structure is one of the most impactful changes you can make. Not only do these features enhance your outdoor living space aesthetically, but they also provide practical relief from the sun — and even a bit of privacy.
But when it comes to choosing between a trellis and a pergola, many homeowners feel torn. They’re both beautiful and versatile, but they serve slightly different functions and have distinct design profiles. So which one is right for your Bay Area backyard?
What is a Trellis?
A Trellis is typically a vertical structure made of a lattice framework, often used to support climbing plants like roses, jasmine, or grapevines. It can be freestanding or attached to a wall or fence. Trellises are generally lighter and more decorative, used more for vertical interest than full shade.
What is a Pergola?
A pergola is a more substantial, open-air structure made of vertical posts and crossbeams, often covering patios or walkways. It provides partial shade — more if you add a canopy or let plants grow over the top — and creates a defined outdoor “room.”
Consider the Bay Area Climate
The Bay Area's microclimates — from foggy coastal zones to sunny inland valleys — should play a big role in your decision.
Coastal areas (e.g., San Francisco, Daly City): These zones don’t often need heavy shade due to frequent cloud cover. A trellis may be enough to add a touch of elegance without making the space feel dark or closed in.
Inland areas (e.g., Walnut Creek, San Jose): These get much hotter in summer. A pergola, possibly with a retractable canopy or trained vines like wisteria, can provide much-needed relief during peak heat.
Style & Design Goals
Go Trellis If You Want:
A vertical focal point or garden accent
A plant-support structure that frames entryways or fences
A lighter, minimalist look
A lower-cost option with less construction
Trellises are perfect if you love the idea of a “living wall” or want to divide areas in a subtle, stylish way.
Installation & Maintenance
Can’t decide? You don’t have to choose just one.
Many Bay Area designers are now incorporating both structures: a pergola for the main patio area, and trellises to create privacy screens or vine-covered pathways. This layered approach enhances flow and makes your outdoor space feel intentional and curated.
