Before starting the actual construction project, we recommend you to plan everything, as to save money and to keep the costs under control. Adjust the size and the design of the wooden carport to suit your needs. In addition, we recommend you to invest in high-quality materials, such as pine, redwood or cedar, as they have a nice finish and are highly durable, especially in a humid environment.

How to build a carport for 3 cars

Fitting the posts

First of all, you need to decide how you will secure the 4×4 wooden posts into place. Fitting the posts in concrete will give you the best rigidity of the frame of the carport. However, you have other solutions, as well, such as pouring concrete footings and using post anchors.

Irrespective of your choice, I really recommend you to read the local building codes and to dig holes under the frost line (at least 2′). Use tube forms and temporarily braces to lock the posts into place tightly for a few days until the concrete dries out.



Lay out the posts for the carport using string and batten boards. Apply the well known 3-4-5 rule to the corners, so you check if they are perfectly right angled. In addition, you need to measure the diagonals and make adjustments until they are perfectly equal.



Fit the 2×6 or 2×8 support beams to the front and back posts. Use a spirit level to check if the support beams are perfectly horizontal. Clamp the beams to the posts, drill pilot holes and then insert two or three  7″ carriage bolts for each joint.



Build the rafters for the triple carport from 2×4 lumber. If you live in an area with strong winds or heavy snow, you should consider use 2×6 lumber.



Build the bottom rafters and the supports for the trusses. Take accurate measurements and then align all the components on a level surface.



Use 1/2″ plywood for the joints, as gussets. Place the gussets over the joints and then insert 1 5/8″ screws to lock everything tightly.



Last but not least, I recommend you to take care of the finishing touches. Fill the holes with wood filler and let it to dry out for several hours.

Smart Ttip: Apply several coats of stain or paint to the wooden components, if you want to protect them from decay and to enhance the look of the flat roof double carport.
