16×20 Shed Plans

by Ovidiu

 

This step by step diy project is about 16×20 gable shed plans. I have designed this 16×20 storage shed, so you can add extra space in your backyard for storing tools, furniture and other items. This shed is easy to build and it has a gable roof. The double shed doors will help you have a great access to the shed. 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.

How to build a 16×20 shed floor and wall frames

Building-the-floor-frame-16x20

Building-the-floor-frame-16×20

First of all, you need to build the frame for the floor. Cut the components at the right dimensions from 2×6 lumber. Align the edges flush and make sure the corners are square. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the joists. Place the joists every 16″ on center for a professional result.

Fitting the skids

Fitting the skids

Attach 4×4 skids to the floor frame. Place the skids equally spaced and use screws or hardware to lock them together tightly. The skids will lift the floor from the ground and this will protect the components from moisture.

Fitting the floor sheets

Fitting the floor sheets

Attach 3/4″ plywood sheets to the floor frame of the shed. Cut the sheets to the dimensions, show in the plans and in the cut list. Align the edges flush, making sure you leave no gaps between the components. Insert 1 5/8″ screws every 8″ through the sheets into the joists.

Side-wall-frame

Side-wall-frame

Assemble the plain side wall frames from 2×4 lumber. Make sure the corners are square and align the edges flush for a neat result. Place the studs every 24″ on center for a neat result. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.

Side-wall-with-window-frame

Side-wall-with-window-frame

Build the opposite side wall for the 16×20 shed. Cut the components from 2×4 lumber and the double headers from 2×6 lumber. Fit 1/2″ plywood between the double headers. Drill pilot holes and insert 2 1/2″ screws to lock the headers. You can adjust the size of the windows, so it suit your needs. The double windows placed on one side of the shed will let enough light inside the shed.

front-wall-frame

front-wall-frame

Frame the front wall for the shed using 2×4 lumber for the studs and plates, while the double header requires 2×6 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Toe-nail the double header to the front wall. Make sure the corners are square and align the edges flush. You can easily adjust the size of the 6′ door opening to suit your needs.

Back-wall-frame

Back-wall-frame

Frame the back wall for the 16×20 shed, using the same techniques described above. You should use 3 1/2″ screws or 16d nails to lock the joints together tightly. Place the studs every 24″ on center and make sure the corners are square.

Assembling the shed frame

Assembling the shed frame

Fit the side, front and the back walls frames to the shed floor, as shown in the plans. Make sure the corners are square and then align the edges flush. Drill pilot holes through the bottom plates and insert 3 1/2″ screws to lock the adjacent walls together tightly. Use a spirit level to plumb the walls. Lock the adjacent wall frames together, by drilling pilot holes and insert 3 1/2″ screws.

Front wall - siding

Fit the T1-11 siding sheets to the front of the storage shed. Mark the cut lines on the sheets and then get the job done with a circular saw. Attach the sheets to the front of the shed and align the edges flush. Insert 6-8d nails to secure the sheets to the framing, every 8″.

Side wall - Siding

Side wall – Siding

Fit the T1-11 siding sheets to the side walls. Align the edges with attention and leave no gaps between the sheets. Insert 6-8d nails every 8″ along the framing.

Thanks for posting these plans! I was dreaming of building a big shed in the back yard almost exactly like this (with the gable trusses spanning on 16ft, etc) and when I stumbled upon this post, I was very happy to find clear, detailed isometric pictures with enough explanation. I’m starting to build mine in 2 days, all materials are ordered, I can’t wait! Thank you so much again for your wonderful post, it’s super helpful! Out of curiosity, I wonder why there aren’t many plans of sheds made out of gable trusses. Everything I see is W trusses or queen’s posts trusses and for smaller sheds like 12ft or less, I see simple trusses (just a triangle). Do you know why there aren’t many gable truss sheds? Are gable trusses more dangerous for live loads like 2 feet of snow accumulation? Thanks!

Reply
Ovidiu -

Yes, if you live in an area with high snow loads, you need those W shaped supports to the truss to enhance the rigidity of the roof. Something like this: http://myoutdoorplans.com/shed/16×24-pole-barn-roof-plans/

Hi thanks for sharing the plans! I have a quick question..what do the measurements of the 2×6 floor joists indicate exm 13 3/4 and 14 1/2?

Reply
Ovidiu -

The distance between the joists.

Reply
antonio jones -

Are all the wall 24″ on center?

Reply
Ovidiu -

Yes, studs are placed every 24″ on center.

Reply
antonio jones -

Also is there a 2×6 on top of all the walls?

Reply
Ovidiu -

There are no 2x6s on top of the walls.

Reply
antonio jones -

i was referring to the top plate on the walls, i see on certain sides its cut 3 1/2 shorter or longer

Reply
Ovidiu -

The double plates are made of 2×4, as well.

Reply
Landow -

What Ovidiu is referring to is the “Front wall – Frame” text that says “double header requires 2×6 lumber”. If I’m reading that correctly you probably want to change that to 2×4.

Reply
Ovidiu -

There’s no need to change anything since the door header actually requires 2×6 lumber.

I see you sell a PDF version plans. Do you also have a CAD file available to purchase in particular a skecthup version. The drawings on the website are great.

Reply

I don’t share the CAD files, it says in the blog FAQs
