A rectangular gazebo is a nice addition to your backyard, as is has both a functional and aesthetic purpose. A large wooden gazebo is great for entertaining family and friends all weekend long. If you want to obtain a professional result and to save money by doing the job by yourself, here’s how to build a rectangular gazebo step by step.

You’ll need:

7′ long 4×4 wooden posts
6” long nails / screws
Tube form
2×6 wooden boards
2×2 balusters
Cement, sand, gravel

How to build a rectangular gazebo. Step-by-step guide

First of all, you have to build footings for the rectangular gazebo, as to make sure the posts will be secured properly. Therefore, you have to dig 10-15” in diameter holes (6” below the frost line – at least 3′), fill 3” with gravel and insert tube forms (or build square forms using 2x4s ). Use a straight edge and a level, to make sure all four footings are horizontal.

Mix concrete, fill the forms and install the adjustable post anchors. After the concrete has dried out completely (about 48 hours), you have to install the four posts into place.

Our rectangle gazebo plans are about a 7×10′ construction, but you can adjust these dimensions to your needs.

After you have installed the four posts into place, you have to build the deck frame of your rectangular gazebo.

Install the decking plumbing the boards to the frame.

Next, install the top plate, using 2x4s or 4x4s. The installation process is straight forward, but you have to remember several tips, to get the job done as a professional. We recommend you to cut out the ends of the post in a L-shape and then, join them together. Insert several 6” screws, after you ensure the top plates are perfectly level.

Carry on with the roof structure as shown.

There are many roofing options but we recommend you to use asphalt singles, as they are both durable and have a neat look. Before installing the shingles, you have to cover the frame either with 2×6 wooden slats or with plywood.
