WALLS

2. Step 1: Mark the wall lines on the floor
The first step is to mark the wall locations on the shed floor.

3. Step 1 (Cont’d)
Start by sweeping the shed floor and then measuring in three and one
half inches from the edges of the shed floor and placing a mark. Do this
on each side of all four corners of the shed floor.
Verify that the distance between the two inner marks is 7 inches
narrower than the overall width of the shed and then use a chalk line to
mark the inner edge of the shed walls on all four sides of the shed floor.

4. Step 2: Cut the wall plates and align them with
the wall marks on the shed floor
The second step is to use the dimensions from the plans to mark and cut
the wall plates to length. Only cut two plates for each wall at this time. You
will cut the double top plate after framing and standing the walls.

5. Step 2 (Cont’d)
Set the wall plates in their final locations on the floor and line them up
with their respective wall marks on the floor and make sure that the ends
of the boards are flush with each other. Also make sure that the corners
meet the adjoining walls and are lined up with the wall marks.

6. Step 3: Mark the wall stud layout and door
opening on the wall plates
The third step is to install layout marks on the wall plates to mark the wall
stud and doorway locations. Start by rolling each set of wall plates on their
edges and make sure that the crown edge is facing up. Flush up the ends of
the boards and make sure that each set of boards are snug against each
other.

7. Step 3 (Cont’d)
Now you are ready to put the layout marks on the wall plates. Hook your
tape measure on the ends of the two plates and pull the tape measure
along the top edges. Put the first mark at 16 and three quarters inches.
Then put an X on the side of the mark closest to the tape measure hook
end to help you remember what side of the mark the wall stud will go on.
Continue making marks every 16 and three quarters inches along the
edges of the boards.
Once all the layout marks are made you will transfer marks to the other
board and make a line across both boards using a framing or speed
square. Make sure that both boards have an X to show the side of the
mark that the wall stud will go on.

8. Step 3 (Cont’d)
The door opening will be marked on the wall plates that the doorway is on.
Measure and mark the doorway trimmer and king stud locations on both
plates. The King stud goes from the bottom plate to the top plate on both
sides of the door header.
You should mark its location with a K instead of an X so that you
remember what it is when you are nailing on wall studs. The trimmer stud
goes on the inside of the door opening to hold up the door or window
header. Mark the Trimmer locations with a T. If there are any window
openings you will mark them in the same way.

9. Step 4: Prepare the wall studs and plates and nail
them together
The fourth step is to make sure the wall studs are the proper length and
then assemble the wall plates and the wall studs by nailing them together.

10. Step 4 (Cont’d)
Measure, mark and cut the wall studs to the length shown on the plans. If
you are building the shed with pre cut 92 5/8" inch studs then you will not
need to cut the wall studs.
You will build one wall at a time so keep the plates for the first wall you
will build on the shed floor and move all the other wall plates off the shed
floor. Make sure to keep the wall plates that go together with each other so
they do not get mixed up.
Separate the top and bottom plates far enough apart so that the wall studs
will fit in between them. Make sure to keep the crowned side with the
layout marks facing up. Also keep the ends that the layout starts on on the
same end.

11. Step 4 (Cont’d)
Set the wall studs on the shed floor between the wall plates with one stud
next to each layout mark. Crown each wall stud and set it close to its
respective layout mark on the wall plates.
You are now ready to Nail the plates to the studs. Align the end of the
wall stud with the layout marks you made on the wall plates and nail the
wall plate to the wall stud. use 2 nails at each connection for 2x4 walls.
Make sure to nail the wall studs on the X side of the layout marks.

12. Step 5: Build the door header
The fifth step is to build the header for the doorway opening. The header
for the doorway is made by sandwiching a piece of O.S.B. between two
header boards and nailing them together. Window headers are built and
installed exactly the same as door headers.

13. Step 5 (Cont’d)
Start by cutting two header boards to the length shown on the plans. Then
cut a piece of O.S.B. or plywood to sandwich between the two header
boards. It should be a bit smaller than the header boards so it does not
stick out around the edges.
Crown the two header boards and then set the piece of O.S.B. between
them, align the edges of the header boards flush with each other and then
nail them to each other using 12d nails.

14. Step 6: Assemble the door opening and frame the
walls with door openings
The sixth step is to assemble the wall with the doorway in it. Mark the
height of the door header from the shed floor on the king studs so your
door will fit properly and then nail the king studs to the header boards.
Now nail the king studs and header assembly to both the top and bottom
plates on their respective King Stud marks.

15. Step 6 (Cont’d)
Now you can finish building the rest of the wall as you did the other walls.
After the wall is framed you will install the trimmer boards. Measure the
distance from the bottom of the header to the top of the bottom plate and
cut a trimmer board for each side of the doorway.
Crown and install the trimmers by nailing the bottom plates to them and
nailing them to the king studs. Make sure to nail from the inside of the
doorway so if the nails protrude they will stick out on the inside of the wall
and not into the doorway.
If there is open space between the door header and the top plate you can
install the cripple studs above the header at this time.

16. Step 7: Stand the shed walls
The seventh step is to stand the shed walls. Start by clearing everything off
the shed floor and sweeping it clean.

17. Step 7 (Cont’d)
Stand one of the long walls first. Align the wall with the wall line marks
and the edge of the shed floor.

18. Step 7 (Cont’d)
Stand one of the long walls first. Align the wall with the wall line marks
and the edge of the shed floor.

19. Step 7 (Cont’d)
Attach the wall to the floor by nailing the bottom plate of the wall to the
floor with 2 12d nails every 16 inches. Try to install the nails so they go
through the bottom plate and flooring into the floor joists below. You can
see where the floor joists are by looking for the nails heads on the floor.

20. Step 7 (Cont’d)
Attach the wall to the floor by nailing the bottom plate of the wall to the
floor with 2 12d nails every 16 inches. Try to install the nails so they go
through the bottom plate and flooring into the floor joists below. You can
see where the floor joists are by looking for the nails heads on the floor.

21. Step 7 (Cont’d)
Stand and nail the remaining walls in the same way. As you stand each
wall and nail it to the floor, flush up the corner boards of the two walls and
nail the two walls together at the corner. Use one 12d nail at 12 inches on
center vertically.

22. Step 7 (Cont’d)
Make sure that the corner boards of the two walls are flush with each
other

23. Step 7 (Cont’d)
Stand the remaining walls and attach them to the floor and to each other.

24. Step 8: Install the wall top plates
The final step to building the walls is to install the double top plates.
Adding a second top plate further locks the walls together and strengthens
the top of the wall to better hold the roof.

25. Step 8 (Cont’d)
Install the double top plate on the shorter framed walls first. Install nails
on both sides of the wall to wall connection to tie the walls together.
Continue nailing along the top plates by using 2 12d nails at 16 inches on
center.
Finally install the double top plates on the longer walls between the first
two top plates you installed.
