This step by step diy project is about simple 12×16 shed with dormer plans. I have many requests for a shed with dormer and a loft. I designed this 12×16 garden shed on a sturdy 2×4 framing and I have you covered with step by step instructions and a full cut / shopping list. In addition, all my plans are PDF download and Print friendly. Make sure you read the local codes so you can comply with the legal requirements. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
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.

It’s that simple to build a shed with a hip roof – Video!
12×16 Shed with Hip Roof Plans
The first step of the project is to build the floor frame. Cut the joists from 2×6 lumber, as shown in the diagram. Drill pilot holes and insert 3 1/2″ screws. Place the joists every 16″ on center and make sure the corners are square. Align the edges flush.
Fit 6×6 skids to the floor frame. Use rafter ties to secure the skids to the floor frame. The skids lifts the floor frame from the ground to protect it from moisture. Alternatively, you can use footings and posts for the shed. Make sure the skids are pressure treated because they will be exposed to moisture.
In addition, it would be a good idea to level the ground under the location for the shed. If you don’t use concrete blocks, you can at least compact a 2″ layer of gravel under the shed. The gravel will drain the water quickly.
Use 3/4″ plywood sheets for the floor. Cut all the sheets at the right dimensions and then lay them on the floor frame. Align the edges flush and leave no gaps between the sheets. Drill pilot holes and insert 1 5/8″ screws every 8″ along the framing.
Use 2×6 lumber for the plates and studs. Cut the components at the right dimensions, as shown in the plans. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center. Use triple studs at both ends of the wall frame. Frame the door opening and adjust the size to suit your needs. Use 2×6 lumber for the triple header. I have also frames two 24″x36″ windows for the front wall of the shed.
Next, frame the back wall for the 12×16 shed using 2×6 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center.
Frame the plain side wall using the info in the diagram.
Frame the opposite side wall and include a window. You can adjust the size of the window to suit your needs. Use 2×6 lumber for the triple plates. You can frame windows to both sides of the shed or to no side of the shed. You can also change the size of the window to suit your needs,
Fit the wall frames to the floor of the shed. Align the edges flush and plumb the walls vertically. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor frame. In addition, lock the adjacent walls together tightly with 3 1/2″ screws. Make sure the corners are square.
Fit the T1-11 siding sheets to the side of the shed. Use a saw to cut out the openings for the side door and window.
Use 5/8″ T1-11 siding sheets for the exterior of the shed. Alternatively, you can go with OSB, house wrap and then siding boards. Use 6d nails to secure the sheets to the wall framing and leave no gaps between the sheets. Use a saw to make the cuts around the double door opening.
Fit the T1-11 siding sheets to the plain side wall of the shed.
Fit the T1-11 siding sheets to the back of the shed. Use 6d nails to lock the sheets into place, every 8″ along the framing.
