2 Car Carport Plans

This step by step diy woodworking project is about 2 car carport plans. The project features instructions for building a double carport made from wood, having a flat roof and sharp modern design. If you want to protect your cars from bad weather, but a garage is too expensive or just too complex for your needs, building this two car carport with a is a great option. Make sure you check out the rest of plans to see alternatives and more projects for your garden.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

How to build a two carport

Laying-out-the-posts

The first step of the project is to layout the posts in a professional manner. Therefore, I recommend you to use batter boards (made from 2x4s) and string. Measure the diagonals and make adjustments until they are perfectly equal. Apply the 3-4-5 rule to the corners to make sure they are right-angled.

Building the posts

Build the posts from 4×4 lumber.  If you want to add more support to the carport, you should consider using 6×6 lumber. As you can easily notice in the diagram, you need to set the posts 36″ in concrete. Make sure you make 4 degree cuts to the top of the posts, for a professional result. You can get by without making the cuts, but it will be harder to align the support beams to the top of the posts.

Anchoring the post into concrete

There are several ways to lock the posts into place. Therefore, you could dig holes in the ground and set the posts into concrete, or you could use post anchors. Nevertheless, taking into account the complexity of the construction, we recommend you to lock the posts into concrete.

Installing the post

Level the posts with a spirit level and secure them temporarily with 2×4 braces. Make sure the top of the posts are at the same level, otherwise the structure of the carport won’t be sturdy enough.

Fitting-the-support-beams

After the concrete sets out, you need to attach the 2×8 support beams to the top of the posts, as shown in the diagram. Align the beams with attention and clamp them to the posts tightly.

Securing the support beams to the posts

Drill pilot holes through both the beams and through the posts. Next, insert 6 1/2″ carriage bolts to lock the beams to the top of the posts.

Building the braces

Build the braces for the carport from 4×4 lumber. Cut both ends of the braces at 45 degrees. Smooth the cut edges with sandpaper.

Fitting the braces

Fit the braces to the sides of the carport. Align the edges with attention, drill pilot holes and use 3 1/2″ screws to lock them into place. The braces will add support to the structure, especially if you live in a windy area.

Building the rafters

Build the rafters from 2×6 lumber. As you can easily notice in the diagram, you need to make notches to the rafters. Use a circular saw to make parallel cuts to the marked areas and remove the excess material with a chisel.

Fitting-the-rafters

Fit the rafters to the support beams and place the equally-spaced. Use metal connectors to lock the rafters to the support beams.

Attaching the roofing sheets

Build the roof of the carport from 3/4″ plywood. Cut the sheets at the right dimensions and place them to the rafters. Use 1 5/8″ screws to secure the sheets into place, every 8″. Leave no gaps between the sheets for a professional result.

Fitting the side trims

Attach 1×6 trims to the sides of the rafters. Use brad nails to secure the trims into place.

Fitting the front and back trims

Next attach the trims to the front and back of the carport. The top trims are made from 1×6 lumber, while the bottom trims are made from 1×8 lumber.

Fitting the roofing

Cover the roof with tar paper. Use staples to secure the tar paper into place. Next, you should install asphalt shingles to the roof, starting from the bottom up to the top. Install a ridge cap to waterproof everything in a professional manner.

Building a double carport plans

After assembling the double carport, you need to take care of the finishing touches. Fill the holes with wood putty and smooth the surface with sandpaper. Remove the residues with a damp cloth. Apply a few coats of paint or stain to protect the components from decay.

This simple structure has enough space for two cars. Make sure you consult a specialized engineer before starting the actual construction. Your project needs to comply with the local codes.

Top Tip: If you live in an area with heavy winters, you should increase the slope of the roof. This carport design is more suitable for area with mild winters.
