Ways to Use Your Single-Car 12×20 Garage

There are more ways to use your 12×20 prefab garage than simply as storage for your vehicle or other miscellaneous tools. Let’s look at some creative ways you can utilize a 12×20 garage.

Home Theater

Turn an unused prefab 12×20 garage into a home theater and create a relaxing space to watch your favorite movies. Add some comfortable seats in the theater, and determine where you want your screen. Adding electricity to your garage is a necessity in this case, and can be something you do yourself, or get done by professionals. Decorate your theater how you like, and add a small fridge for snacks and drinks. There are many ways you can personalize your own home theater!


If you need some extra space to keep guests, then consider how you could turn a 12×20 portable garage into a guest house! Get the necessary electrical work done and think of insulating your garage too. A garage this size can include a bed, bathroom, and maybe a kitchenette. Decorate your guesthouse to make it practical and comfortable for your guests. This can be an affordable solution to keep guests out of your house space.

Man Cave

Would you like an area on the property where you can get away from it all? How about converting your garage into a man cave? The steps to converting your garage into your retreat would not be that difficult. Choose a theme and layout of your man cave, decorate it, and personalize it to your taste. You may want to consider insulation or ventilation in the cold and hot months and decide on some type of temperature control for your man cave. Add some shelves to store your personal items and a comfortable area where you can relax.

For those who want a basic garage with no extra frills or customizations and with cheaper materials, you can expect to pay anywhere from $3,000 to $6,000, though it will vary based on your shed builder and things like delivery fees.
