For this DIY project, I built 8 ft. x 6 ft. shed, instead of buying one. This is also my first shed build.

Step 1: Tools

Let’s start with tools used:

Hammer

Showel

Miter Saw

7-1/4 in. Circular Saw

Jig Saw

Impact Driver/Drill

Speed triangle

4 ft. Beam Level

Caulk Gun

Various clamps

Kreg K4MS Jig Master System

Step 2: Materials

Nails: 1 box of roofing 1 1/4 in, and two boxes of 2 in. 6D Exterior Galvanized nails.
Screws: 3 1/2 in. exterior grade (5 lb box) and 2 1/2 in. exterior grade (1 lb box) screws.

Floor:

I built floor/ foundation from 2 in.x 6 in. pressure treated lumber.

7 x (2 in.x 6 in. x 8 ft.) Pressure treated

2 x (3/4 in. x 4 ft. x 8 ft.) Ground Contact Pressure Treated Plywood

6 x (4 in. x 4 in.) posts I had these left over from fence I built.

2 x 50 lb. Fast-Setting Concrete Mix

2 x 10 oz. Liquid Nails Heavy-Duty Adhesive

Walls and Rafters:

All the walls, rafters and the doors are built using 2×4. You will need quite a few of these. My shed I used 24 in. on center spacing for walls studs instead 16 in. on center spacing since shed is very small so it would not need extra wall studs.

40 x (2 in. x 4 in. x 92-5/8 in.) Prime White wood Studs

Roof:

1 x Roll of #15 Felt Roof Deck Protection

3 x Bundle 3-Tab Shingles

4 x (7/16 in. x 4 ft. x 8 ft.) OSB TechShield Radiant Barrier

2 x 4 ft. Long Roof Ridge Exhaust Vent

4 x 10 ft. Galvanized Roof Edge Flashing

Siding & Trim:

7 x (48 in. x 96 in.) Composite Panel Siding

15 x (3/4 in. x 2 in. x 8 ft.) Pre-Primed Composite Reversible Trim

4 x (3/4 in. x 6 in. x 8 ft.) Pre-Primed Composite Reversible Trim

1 x 10 oz. tube of Exterior Caulk

Step 3: Foundation

I cut two 2×6 at 6 ft. for shorter sides and for long sides got two uncut 8 ft. 2×6. Then I made rectangle box using 3 1/3 screws and placed to desired location. I then dug six 1 ft. deep post holes and used various left-over 4×4 for the posts.

One I was happy with location of all posts. I used Fast-Setting Concrete Mix to secure posts. For fast setting concrete, you just pour in the post hole and add water. It only takes 30-40 minutes to make concrete hard as rock.

To ensure shed floor is level I used 4 ft. level and raised each corner until was perfectly level on all sides. Then used 3 1/2 in. Screws to secure it to posts and cut the tops to be flush with top of the 2×6’s.

Next I installed 3 cross support 6 ft. long beams spaced at 24 in. on center and used left-over pieces to add strength to the floor by adding smaller cross support pieces.

For the floor, I cut each plywood sheet to 4×6 ft. long and used liquid nails and 2 1/2 in. Exterior screws every 12 inches to secure to the foundation.

Step 4: Build Roof Trusses

To build roof support, I opted to use lower pitch roof since shed is small, and we do not have any snow here in Texas. There are a lot of great videos on YouTube on how to build roof trusses. I choose to build 4/12 roof pitch (or slope). This means that the roof rises 4 inches for every 12 inches inward towards the peak (or ridge). I built trusses on the shed floor prior to putting up walls. Basically, you build first one then use 2 1/2 in. screws or nails to secure the peak with left-over plywood.

Once initial one is made you secure it with left-over blocks and build others just like first one. My shed will have them spaced at 24 in. on center so I would need 5 trusses.

Step 5: Walls

To build walls you will need 4 2×4 at 8 feet long for two sides, and you will cut others down to desired size. For walls height, I wanted studs to be 6 ft. tall, so I started by cutting 2×4 @ 6 ft. I needed 18 studs cut at 6 ft. for all four walls. Afterwards I assembled first long wall with two 8 ft. studs for top and bottom next spaced each 6 ft. stud at 24 in. on center. So for longer 8 ft. wall you will need five 6 ft. studs and 4 for each smaller wall.

Build two longer walls then do same for smaller back wall, which will also have studs at 24 in. on center.

Raise the walls:
Since I was doing all work by myself, I used old 2×4 to hold the walls up while I secure them to each other. As you see below I built front door opening at 3 ft. wide and built header by using two 2×4 sandwiched with the piece of osb in between to make it as thick as 2×4 stud.

Basically stand up all four walls and use 2×4 just to hold them up.

Next we use 4 ft. level to ensure walls are level vertically and secure each wall to one another and floor with 3 1/2 in. screws. Additionally, add 2×4 on the top for top plate.

Top plate secures wall to each other and creates a level surface for roof trusses.

Step 6: Roof Support

Started to add roof trusses, and I used spare piece of 2×4 just to hold first end truss in place temporary.

Placed all 5 trusses at approximate 24 in. on center just like wall studs

Then secured each one with two 3 1/2 inch screws at each side at 24 in. on center to the top of the walls (top plate).

After used another 8 ft. 2×4 for the end of truss and secured with 3 1/2 inch screws.

Added another 8 ft. 2×4 on other side of roof truss.

Step 7: Roof Panels

Because each side of a roof is not 4 ft. wide, I had to cut each roof panel long ways to make it fit. In addition, my roof will have a ridge went so 1 in. Opening will be left on a top on each side. Roof panels were cut at 44 1/2 in. Wide and left them 8 ft long. Then I used screws to secure it to the roof trusses. This also helps you square the roof trusses.

Then same will be done on the opposite side on the roof.

Then we will put the felt paper on the roof. To better insulate and protect from rain, I also used same felt paper and wrapped the shed

Step 8: Siding

I jumped the gun and did not take pictures of adding composite panel siding and roof trim. Basically, you take your 4×8 ft. siding panels and place next to building and cut extra from top with same pitch as your roof. For door, I left opening 1 inch bigger on siding for the double doors. I nailed the panel where studs are with 2 1/2 nails every 6 inches.

Side panels are the same and easier you just cut them how long you want them ( mine was 81 inches long) and then nail with 2 1/2 inch nails at 24 in. on center. I spaced nails every 6 inches

Step 9: Doors

I did not cover how you shingle the roof since there are tons of great videos on You Tube on this. For the entrance, I wanted to have double doors instead one large door. Then I used sandwich method where you use 2×4 in the middle for the frame then you add OSB for the back and siding for the front. It’s all secured with screws.

Then we use 2 in. Trim around the door frame and on the doors to make them look better. Additionally, attached 6 in. Door hinges.

Then added basic door latches on the doors
