How To Build A Attached Double Carport
This step by step diy woodworking project is about 12×24 attached carport plans. I had many requests for a large 12×24 carport with a lean roof. This carport features a sturdy 6×6 framing and a roof with a 3:12 slope. The roof structure is built on a sturdy 2×10 rafter structure, every 24″. This is a wooden carport that is easy to build an budget friendly.
Attach Beams and Rafters Cut the side beams and clamp them to the posts, aligned horizontally on the outside of the carport, so the tops of the beams are flush with the tops of the posts. Bolt the beams to the posts. Align beams to the front and back of the frame and attach with bolts. Attach the Roof. Once you have measured and cut your roofing, attach it to the top of both the bearers and the rafters. Make sure that the roof screws are fitted with rubber washers before tightening them. You will also want to make sure that your carport roof extends several inches beyond the frame for rain and snow runoff.
In most of the cases, a building permit is required so make sure you go to the town hall and ask information about the legal requirements you have to comply with. In this manner, you will also find out useful details about your carport construction. When building the carport, you should make sure the plans are detailed and come with step by step instructions, as well as with a complete list of the materials.

Building an attached carport
Laying out the posts
First of all, you need to build the posts for the attached carport using 6×6 lumber. Layout them using the info in the diagrams.
Attached Carport Building Plans
Dig 3′ deep holes and fit tube forms, after compacting a 2″ gravel layer on the bottom of the holes. Make sure the 4×4 anchors are perfectly aligned before filling the tube forms with concrete. Level the surface and let the concrete dry out for a few days. Use temporary braces to lock the posts into place, until you build the structure for the attached carport.

Cutting the top of the posts
In most cases, you won’t be able to have the top of the posts level from the very beginning. That is necessary to use a laser level and cut the top of the posts so they are perfectly horizontal one with another. Leave the braces in place until you add the rafters.
Fitting the top beams
Build the support beams out of 6×6 lumber. Fit them to the top of the posts. Use a spirit level to make sure the beams are horizontal. Notice the 12″ overhangs on the sides of the carport. Use post to beam connectors to lock the posts to the beam. Insert 2 1/2″ structural screws to lock the components together tightly.
Fitting the braces
Use 6×6 lumber for the diagonals. Make 45 degree cuts to both ends of the braces. Check if the corners are square and add the braces to the frame. Drill pilot holes and insert 5 1/2″ screws to lock the braces into place tightly.
Next, you need to attach the 2×8 support beams to the building. Take accurate measurements, as the support beams and the ledger boards need to be level. Level the beam with a spirit level, drill pilot holes and insert lag screws into the building to create a rigid bond. Remember that you need to read the local codes, so you use the right anchoring method. This also differs according to the type of the support wall (wood frame, concrete, bricks, etc.).
Rafters
Use 2×8 lumber for the rafters. Mark the cut lines to the rafters and use a circular saw to make the cuts, as shown in the diagram.
Next, fit the rafters to the top of the carport. Place the rafters every 24″ on center. Use rafter ties to lock the rafters to the support beams. Drill pilot holes and insert 3 1/2″ screws to secure the rafters to the beams. In addition, I recommend you to use L strong ties and 1 1/2″ structural screws to lock the rafters to the ledger.

Roof sheets
Attach the 1/2″ plywood to the roof structure, starting from bottom left. Align the edges flush and insert 1 5/8″ screws, every 8″ along the framing. Leave no gaps between the sheets,
Attach the 1×6 trims to the front of the shed. Use 2″ nails to lock the trims to the side rafters.
Install the 1×6 trims to front of the carport. Use 2″ nails to secure the trims to the ends of the rafters. Align the edges flush.
Fitting the roofing
Attach the tar paper to the top of the lean to carport. Align everything and staple them into place tightly. Install the drip edges to the sides and bottom of the carport.
