Size of the Building
The golden rule to build a highly-functional RV garage is to build it as large as you can. Consider the size of your RV and upgrades you might want to do in future, and build a garage that is spacious enough to accommodate your RV and your future RV needs.
Also, if you plan to use your RV garage as a storage space for your tools, lawn mowers, or any other materials, don’t forget to add extra space for them.
Type of Motorhome | Height of Motorhome | Length of Motorhome | Size of Garage |
---|---|---|---|
A Class A Motorhome | 10 feet | 21 to 40 feet | 50’ X 14’ |
A Class B Campervan | 8 feet | 16 to 21 feet | 30’ X 12’ |
A Class C Motorhome | 10 feet | 21 to 35 feet | 45’ X 14’ |
Type of Garage
You may build your RV garage as a detached structure or as an extension to your home. An attached RV storage garage shares one of your house walls and usually incurs less cost as compared to a detached garage. Building a detached RV garage offers you greater design flexibility but costs about $2,000 more than a same size attached garage.
Your Choice of Add-ons
Adding luxury features and amenities may increase the cost of construction. Some amenities that you may consider adding to your RV storage garage include electrical connectivity, insulation, automatic opening, drainage system, etc.
