I just finished "re-modeling" my garage...before I touched it it had just taped drywall and concrete block walls, unfinished cement floor, wires for the garage door openers hanging all over the place, holes in all the walls/ceiling. It was a typical, dirty, dark garage.I painted the concrete walls with Behr waterproof masonry paint and the rest of the walls and ceiling with the same color behr paint (twilight gray-to lighten it up).I did the floor with Behr 1 Part Epoxy, which, takes forever to prep for, but the result is worth it. You first need to sweep very good, then clean/de-grease and etch the concrete using a floor cleaner rented from HD...then let it dry. I let it dry for about 2 weeks. Once I was sure the concrete was dry, I applied 2 coats of concrete bonding primer. I let that dry for about 24 hours, and I was finally ready for the paint. The paint goes on easy, one coat was plenty. I sprinlled in some color flakes and let it dry 24hrs. I then began my first of three coates of low gloss sealer. The finished result was very pleasing...I then re-installed my Gladiator Garage Works 8 foot work bench, wall cabinet and tool chest as well as a second wall cabinet and large gearbox that I purchased for my new garage... I also built a wooden cabinet around the circuit breakers and painted it gray along with the framing for the garage doors, a beam in the middle and the door into the house. I finished with gray vinyl trim molding around the walls.I also mounted the bikes, a shop Vac and misc. brooms, saw horse, etc... on the wall(s). All of the wires from the garage door openers were hanging down and sloppy (prev. owner) so I disconected everything and ran it through PVC for a cleaner look. I then added a few finishing touches, Bud Light neon clock, pictures (NE Patriots Cheerleaders), and mounted my novelty license plate collection as well as a few other items...Moving all of my furniture/tools out of the garage was a big project in itself, and I lost my basement(i.e. Gym) for about a month and a half, but the end result is a very clean, organized garage that is "my" place...
Heating & AC ($1000-$5000): Adding central heat and air into your garage can either be simple or difficult. If you have a robust heating and air conditioning system in place it is as simple as expanding your existing ducting. If the additional square footage is more than your system can handle you will need to add in a new unit. Luckily, a small garage usually is able to be fit into your existing system.
If you don’t want to spend $10,000 on a garage remodel, you could partially finish your garage. You can frame a concrete garage the same way you you’d finish a basement. Wooden crossbeams are secured to the floor, and the remainder of the framing is built up from there. Walls of either paneling or sheetrock can then be fastened, making your garage look and feel like another room of the house. Sheetrock is very often used for garage ceilings, allowing you to choose a paint color, and the same can be said for the walls. This is a job any general contractor can accomplish for a few thousand dollars. You could use metal studs, as opposed to wood, when framing to cut down material costs significantly.
SketchUp has a massive library of over 2 million free user-created models to get you started in what they call the 3D Warehouse. You don’t have to re-invent the wheel… you can just download it! Need to add a garage door to your plans? It’s in there. How about a workbench? That’s in there, too, available to drag-n-drop right into your design. In fact, many of the items you’ll find you want to add to your own plan can be turned into plans themselves—like a homemade workbench.
So if you are in need of a garage but don’t have a lot of money then consider this option. It could still be used as a great protector of your vehicles and other items. And would certainly make a great workspace as well. The only thing I wouldn’t be certain about would be the storage of personal items. But that could be worked around if this project could be done on a budget that works for you.
And you really need your investments protected, but you just don’t have the funds to build some of these other options. Well, don’t give up hope. This video shows you how to build a pretty decent structure that will do what you need it to do for basically no money. And honestly, if you have the materials on hand it could actually be built for free.
