Barn Shed with Porch Roof Plans

by Ovidiu


This step by step diy project is about barn shed with porch roof plans. This is PART 2 of the barn shed with porch project. In this article I show you how to frame the deck and build the roof for the construction. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.

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.

Barn Shed with Porch Roof Plans



Continue the shed project by fitting the 2×4 supports to the gambrel ends. Drill pocket holes at both ends of the supports and then secure them into place with 2 1/2″ pocket screws. Make sure you align the edges flush for a neat result.



Cut the siding panels to the gambrel ends from T1-11 siding. Attach the panels into place and then secure them into place tightly using 8d nails.



Assemble the overhangs for the shed using 2×4 lumber and my plans. First build the two trusses using screws and then attach the blockings. Drill pilot holes through the trusses and insert 2 1/2″ screws into the blockings.



Attach the blockings to the front and back of the barn shed. Align the edges flush and then secure the blockings into place with 3 1/2″ screws.



The next step of the project is to frame the deck for the porch. In order to keep the costs down, you can use 2×4 lumber for the frame. Cut all the components at the dimensions shown in the diagram. Drill pilot holes through the rim joists and then insert 3 1/2″ screws into the perpendicular components. Make sure the edges are flush and check if the corners are square.



Attach 4×4 skids to the deck frame. Align everything with attention and use metal connectors to lock everything tightly.



Fit the deck to the front of the shed and insert 3 1/2″ screws, so you lock it into place tightly.



Use 6×6 lumber for the porch posts. Mark the cut lines on the top of the posts and remove the excess material with a circular saw. Smooth the edges with sandpaper.



Fit the posts to the deck of the shed. Use a spirit level to plumb the posts. Drill pilot holes through the deck frame and insert 3 1/2″ lag screws into the posts, so you lock them into place tightly.



Attach 1×6 decking to the porch. Make sure you place a nail between the boards, so they can expand and contract properly. In addition, the water will drain faster and a lot easier. Make a few cuts so you can fit the boards around the posts.



Attach the 2×6 support beams to the top of the posts. Align the beams with attention and then lock them into place with clamps. Drill pilot holes through the beams and through the posts. Insert 6″ carriage bolts so you can lock the components together tightly.



Build the bottom rafters for the porch from 2×4 lumber. Cut one end of the beams at 15 degrees.



Attach the rafters to the shed, as shown in the plans. Use rafter ties to lock the beams both to the shed wall and to the support beams. Place the rafters every 16″ on center, as shown in the diagram. Use a spirit level to make sure the bottom rafters are perfectly horizontal.



Build the rafters for the porch. Cut one end of the rafters as shown in the plans and smooth the edges with sandpaper.



Fit the rafters to the porch of the barn shed. Place the rafters every 16″ on center. Drill pilot holes through the rafters and lock them into place with screws.



Attach 2×4 supports to the front and back lean to ends. Make 15 degree cuts to the ends. Drill pocket holes at both ends of the supports and secure them into place with 2 1/2″ pocket screws.



Fit T1-11 siding panels to the lean to ends. Use 8d nails to secure the panels into place tightly.



Build the overhangs for the porch from 2×4 lumber. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blockings. Add glue to the joints and leave no gaps between the components, for a neat result.



Attach the overhangs to the front and back of the porch. Align the edges with attention and insert 3 1/2″ screws to lock the overhangs into place tightly.



Make sure you check out PART 3 of the project to see how to install the roofing sheets and to build the doors for this backyard shed.



This is a complex shed project, so you should take your time when building the structure. Don’t forget to take a look over PART 1 and PART 3 to learn how to build the frame and the doors for the shed.
