Garage extension

The garage in back is already a 1-1/2 car detached garage with a carport. I decided to enclose the whole thing and will knock out the wall so we’ll have a small workshop and park both vehicles inside. As I aim to finish the sprinkler system tomorrow (Monday), I decided to frame in the east wall so we could mount the sprinker system control box inside.

It is always best to install the control box in a place where you can view the yard. This way you can test zones and be sure they turn on or off. Here are some photos of my progress. I still have to cut a remaining sheet and then add some screws in some areas to really secure all the sheets to the studs.

Loaded my truck up with lumber from the store
I took measurements and planned out my “shopping list” before visiting the local Home Depot. As they were open on Sunday and I got the urge for this project just around lunch time, we didn’t shop around and just bought everything there.

The sheets were only $12-13 each and the studs (8-footers) were only $1.99 each. The treated 2×4s were just under $5 each and boxes of nails were $3 and $5 respectively. We bought 24 studs, 5 treated 8-foot 2×4s and 6 sheets of 5/8″ sheeting for just over $150.

Pre-cutting all the studs
I pre-cut all the lumber before clearing an area to assemble the walls before putting them in place.

Assembling the walls on the ground
Rather than trying to build the walls in place, it’s best to assemble them on the ground and then put them in place. As you can see, I used pressure treated lumber for the section that touches the concrete and ground and standard lumber for the rest.

Raising the walls up and nailing into place
My professional photographer, Jamie, caught this “action-packed” photo while I was raising the first wall section. I should have placed some thin foam strips on the ground first under the treated lumber for moisture and bug barrier but instead I will simply use caulking and glue to seal the floor.

Fitting the wall section
Fitting the wall into place before making it plumb with a level, then tacking it into place with nails. After I finish the job I will rent a hammer drill and use a special bolt called “Red Heads” to anchor the bottom plate to the concrete.

All the studs in place

First sheet
Installing the first sheet is very important. You must make sure it is square so all the other sheets you install and butt up against it will all fit.

From the inside
View from the inside. Now I did not take into account the 4×4 posts that existed so you can see that the sheet does not end on a stud. I will correct this by screwing in 2×4s between the studs that I can nail the sheets against to ensure they have a good hold before siding the garage.

Almost done
I simply need to cut the remaining sheet and finish fastening the walls. As I have not purchased the garage doors, I am unsure on the rough opening specs so I cannot build the front and back walls yet. Depending on how busy I am this week with all my work projects and meetings, I will try to get those measurements and purchase the materials to finish the garage.

More to come… :)

    How did this turn out?

    Still a work in progress, unfortunately. Need to frame out the front/back and run a beam before knocking out the center wall and only so much time in-between growing the business. We took a break this winter and starting the home projects again soon. :-) I’ll post more pics when we get this project knocked out. Thanks!
