## What's Included in These Wood Louvered Pergola Plans

This 12x18 pergola plan builds a boxed roof frame of rafters and rim boards and fills its nine bays with fixed wood louvers. Every louver is a 2x6 cut to one length, set at 45 degrees with a simple spacer jig and pocket-screwed to the rafters. Face the front toward the sun and the louvers block the high midday sun while you still see the sky.

## Louvered Roof Pergola Blueprint Format and Units

The pergola blueprint is a 23-page PDF on US Letter paper. All dimensions are in feet and inches to 1/16" precision, and the main cut lengths are also given in millimeters. Drawings are not to scale, so you always build from the written dimensions.

## Who This Modern Wood Pergola Plan Is For

These freestanding pergola plans suit DIY builders with some framing experience and a pocket-hole jig. You need a level area of about 25' x 20'. A lounge set and a dining table both fit under the 18' x 12' roof, and the louvers give far more shade than an open slat roof.

## How to Use the Louvered Pergola Plans

1. Buy the plan and download the PDF.

3. Check local zoning, permit and height rules for your area.
4. Buy the lumber and hardware from the shopping list.

## Digital Product Note

This is a digital PDF plan. No physical item is shipped, and no lumber or hardware is included. The file is ready to download right after purchase. Spring is the busiest building season, so fall and winter are a good time to plan a louvered pergola and cut and stain the louvers.

### Can you build a louvered pergola yourself?

Yes, you can build this wood louvered pergola yourself with standard lumber, a miter saw and a pocket-hole jig. The plan walks you through every cut and all 207 louvers in 7 steps.

### Can I turn the louvers on this pergola?

No, the louvers on this pergola are fixed at 45 degrees. Choosing which side faces the front lets you aim them at the sun.

### Does a louvered pergola keep the rain out?

This louvered pergola gives a lot of shade and breaks up light rain, but it is not a roof. Water runs between the fixed louvers.

### Is it cheaper to build or buy a pergola?

Building a pergola from plans lets you buy lumber locally at your own prices instead of paying for a pre-built kit. The shopping list in this PDF lets you price the full build before you start.
