## Pergola Blueprint Format, Paper Size 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, with the main cut lengths also given in millimeters. Drawings are not to scale, so you always build from the written dimensions.

## Who This Freestanding Pergola Plan Is For

These freestanding pergola plans suit DIY builders with some framing experience who want a 16x12 V roof pergola with a slatted roof. The frame stands on six 6x6 posts set 36" deep in concrete, so it does not need to be attached to a house. You will need a helper, and a third person makes setting the beams easier.

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 many builders order plans in fall or winter and buy materials ahead of time.

## Frequently Asked Questions

### How do I download the PDF after purchase?

After checkout you get a download link on the order confirmation page and by email. Click the link to download the butterfly roof pergola plans PDF.

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

Building from pergola plans lets you buy the 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.

### What are the disadvantages of a butterfly roof on a pergola?

A solid butterfly roof needs a gutter in the valley, but this pergola has an open slat roof, so rain falls through and water does not collect in the valley.

### How tall is this 12x16 butterfly roof pergola?

The highest point of this 12x16 pergola is 12' 8" above grade, and the clear height under the valley beam is 8' 0".

### Can I build this pergola on an existing patio?

Not as drawn. This pergola gets its stiffness from posts set 36" deep in concrete, and a paver or concrete patio can be laid around the posts after the build.
