Introduction: Enclosed Overhead Garage Storage
When we bought this house, we knew that the garage wasn't ideal for my wife and I, as it was a little small and didn't have any storage space. We had to get creative and decided to build an overhead storage space in our garage. Because the garage is my workshop for projects, I decided to enclose the storage to keep out dust and debris. While building this, we also wanted to unify our storage system and used all the same clear totes.
This instructable was our result! I'll include the list of parts in case you want to copy my exact plans for OUR garage. Keep in mind your garage may not be the same size and will require different measurements. My goal is to thoroughly explain the process I did so you can adapt it to your own space.

Step 1: Initial Tips
I have enjoyed adding this step to share some initial tips and insights to be aware about something later and/or help get you started based on things I learned while working on this project.
SAFETY FIRST! SAFETY FIRST! SAFETY FIRST!
Please use proper eye & ear protection!
Please use all safety guards on your tools!
Since likely using a ladder make sure it is properly placed before climbing as many accident happen on ladders.
Please read and understand how to use and operate your tools as they might not match how mine are used.
I hope this instructable can serve both as a instruction manual, as I'll provide my dimensions, but also as a tool that you can use to change it up to your needs. THIS IS VERY IMPORTANT as the height clearance and spacing above your garage door is very likely different than ours. So whether that is making it bigger or smaller, changing doors and access, or more. The only limit is your imagination.
The biggest most important measurement with this project when placing above the opened garage door is measuring the clearance as you would hate to have the garage door hit your work of art. Make sure to measure both ends towards the front and back of the opened garage door as both ends might not be the same height. Also if placing above/close to where the door turn from vertical to horizontal, watch and measure the highest point that the garage panel corners stick up.
Then once you figure out your height minus an inch or more to provide some extra clearance. Also if planning for storage bins and picking the right size make sure to factor in the height of the bottom 2x4 and 3/4" plywood
There can be more than one way to go about a build process that I share here. You may have different tools than what I have. The important thing to remember is to use your tools in a safe manor For example, I used pocket holes, which some might argue don't hold the weight, but you could just screw in straight from the outside. Another example is that I don't have a table saw to cut the plywood so I used my Circular Saw with the Kreg Accu/Rip Cut jigs. Just make sure to put safety first and to read the owners manual for your tools!
Measure twice (or trice) and cut once. :)
Step 2: Find Joists and Mount First Pieces
First we want to find the location of our joists in the ceiling if they aren't exposed. Thankfully I had a joist inline with the front of our opened garage door while being able to hit a joist 48" deep. Ceiling joists are typically installed either 16" or 24" on center and mine were spaced at 24".
Three key decisions have to be made here: the depth of your shelf, the width of your shelf and how many openings you want. My answers are below.
After you have made your decisions, I cut 4 - 2x4s to my depth measurement and put 2 pocket holes on both ends. I then measured out my first side placement and attached it to the ceiling (pocket holes down) using 3 long screws on either end and 2 screws into the center joist. I measured out the desired spacing and attached the next board and repeated for all upper pieces.
Depth of Shelf
I decided on 48" due to 4x8 sheet of plywood. This made the job easier with cutting the plywood as well as it matching the joist spacing.
Width of Shelf
I decided on 6' 6". That was the spacing I had from the garage door track to the center chain, minus some clearance and then went with a clean measurement (ie the 6" vs 7" or 5.5")
Number of Openings
There were a couple of factors to determine the opening size. One factor was that we wanted to have gasket storage bins. Because we were limited in our height, that narrowed the options of bins to pick from. I also wanted to make sure I could get our bins in and out easily. I also thought about looks and functionality. I decided that three doors would offer nice spacing, allow me to easily get bins in and out, and added two extra support locations for the shelf. I originally wanted to make the doors as sliding panels. *Keep in mind to factor the width of each vertical 2x4 when planning out the opening space.
Step 3: Add Vertical Supports
Next we will add the vertical support pieces. These are to be measured out to the full available height of the planned storage shelf. For example, take your total space from ceiling to garage door and subtract the desired clearance. This will give you the length of the vertical supports.
Here I attached the vertical supports using the pocket holes drilled out in the previous step. You could also skip the pocket holes and drill straight into the horizontal beams. Attach each vertical support to each side of all ceiling attached boards.
*Tip: I found it helpful using the Kreg Pocket Hole Right Angle clamp to hold the vertical support in position to get the screw in.
Step 4: Add Lower Horizontal Supports
Cut 4 more pieces of 2x4s measuring the depth of your storage shelf. This should match the pieces cut in Step 2.
Again drill out 2 pocket holes on both ends (or skip this and just drill screws straight in from the sides).
Here we will attach to the bottom of our vertical supports. Make sure to have the pocket holes on the top side and that our bottom is flush with the bottom of the vertical supports.
*Tip: I found using the pocket hole right angle clamps to be helpful with holding up the opposite end while securing the other end.
Step 5: Cut and Add Bottom Shelf
Next we want to cut our 3/4" plywood to size for our bottom shelf piece. For mine I only had to reduce the length to 6'-6".
For the next step I HIGHLY RECOMMEND GETTING A FRIEND TO HELP. Between the potential height and weight of the 3/4" plywood, having an extra set of hands is crucial.
Due to my space and the center garage bar and chain, I had to insert the plywood board between the third and fourth support pieces, pushing it up at an angle and going past the outside edge. Once the board was fully above all the bottom supports, I then pushed it back over the fourth support, getting all edges flush.
I then screwed down the 3/4" plywood to the bottom support pieces. Make sure to check the spacing measurements of the bottom of the vertical supports so they match the top of the vertical supports so they are square.
Step 6: Add Side Supports
Here we will add extra support pieces on the side. In my opinion, these add style to the build, but also serve additional support functionality.
Cut 4 pieces of 2x4s that measure the height of the full storage shelf. Attach and screw them on the side of each corner, making them flush with the front edges. I would recommend that you make sure to get a screw in the vertical support piece as well as the ceiling mounted board and repeat at the bottom. In addition drive in screws along the length of the board.
Step 7: Add Side Horizontal Boards
These next pieces help with adding to the styling, but also will act as a mounting spot for our side panel plywood.
Measure between the two side vertical supports added in the last step and attach at the top and bottom of our shelf.
I decided to add a single pocket hole on each end to drive into the vertical support for the half of the board that sticks into the center open space to add additional stability.
Mount them on each side all the way to the top and the other one at the bottom with its bottom edge flush with the bottom of the shelf unit. Drive in screws along the length of the board and then drive in the pocket screws on the inside.
Step 8: Cut and Add Side Panels
Measure the inside height and depth for each side panel and cut that out in your thinner plywood. I had 1/4" available and that worked well in my opinion, but feel free to go thicker if desired.
Place and insert each board from the inside pushing it up to the pieces we added in the last two steps. You could attach these with short screws or nails. I used my 18g nail gun and attached it along the sides, top and bottom edges to secure the panel into place.
Step 9: Door Panels
Next is adding the door panels. Originally I wanted a solid panel along the back with doors in the front, but after having just the frame up I didn't like the idea of having to remove everything in the front to get to a tote or item in the back. With my wife being shorter, she wouldn't be able to reach something farther in the back. I decided to do 6 doors, 3 in the front and 3 in back, with a bottom hinge. I thought this might be easier to deal with while on the ladder while removing the door and hardware from being in the way.
To copy what I did, measure the width of your opening and the height from the bottom edge of the shelf panel to the ceiling. Hopefully all 6 measure the same and you can cut them out using a table saw, track saw or the Kreg system with a circular saw.
I used 1/4" plywood, but would recommend 1/2" due to the mounting hardware and screws. I added some wooden spacers with the hinges and you can see some blocks on the back side with the barrel bolts.
Mount 2 hinges along the bottom edge of the door and then attach to the front face of the 3/4" plywood shelf. Continue repeating for each door.
Step 10: Door Stop Blocks
I added some stop blocks at the top of each side for every opening to add as a stopping point when closing the door.
I cut a 1" piece out of spare 2x4s and then cut that piece in half. I took my nail gun and attached them to the ceiling mounted board keeping flush to its end. I did this to both sides of each opening.
Step 11: Add Barrel Bolts
Finally I added some barrel bolts to secure the doors in a closed position. I mounted these about 2-1/2" down from the top of the door panel and on the right hand side. As you can see in the photo, due to the mounting hardware I needed to add an extra support block to secure the screws into.
Instead of using the piece the bolt slides in to secure itself, I drilled a hole into the vertical support.
*Tip: The trick is figuring out where to drill the hole. I used my Milwaukee Inkzall Marker. Most markers should do and colored in the tip of the barrel bolt (as you can see in first photo). I closed the door panel making sure it touched the stop blocks. Then I slid the barrel bolt into the 2x4, pushing in and twisting to leave a mark. I then opened the door panel to drill where the mark was made.
Step 12: Additional Options
Along with this project, I decided to upgrade the lighting in our garage to have a better lit work space. I got a pack of 8 LED shop lights from Amazon and mounted them to the underside of the storage unit. They have a small profile that fits within the bottom 2x4's, thus not adding to the profile of the shelf.
I also hardwired them because that was an install option. Before I added one of the side vertical boards I routed a groove for the wiring to run facing the inside. Then when I installed the side panel the wire was enclosed and went straight into the attic to be wired.
As part of the plan with this project, my wife and I wanted to get eliminate the many different totes we had and get all the same size to have more unified organization. We also wanted to get totes that had a gasket seal to help prevent excess moisture and dirt getting into them. We went with the Sterilite gasket totes and picked the size that worked best for the spacing above the garage door.
