Barndominium Plan with 3-Bay Garage and One-Bedroom ADU

Barndominium Plan with 3-Bay Garage and Private ADU

This barndominium plan with 3-bay garage combines a substantial garage and workshop with a private one-bedroom apartment on the upper level. Plan 22025 is designed for homeowners, hobbyists, RV and boat owners, collectors, small-business operators and anyone who needs flexible space for vehicles, equipment, projects or storage.

The first floor provides 2,680 square feet of open garage and workshop space. Three oversized garage bays accommodate vehicles and larger recreational equipment while leaving room for workbenches, tools and organized storage. A convenient powder room serves the garage level, reducing the need to enter the apartment while working or entertaining downstairs.

Private One-Bedroom Barndominium Apartment

The second floor contains an 893-square-foot living area with one bedroom and one full bathroom. Its open arrangement connects the kitchen, dining and living spaces, creating a comfortable apartment that feels efficient without feeling confined.

The kitchen includes an island with seating and opens directly to the living area. A dedicated laundry space, full bathroom and private bedroom provide the essential features needed for everyday living. This upper-level space could serve as a primary residence, guest apartment, caretaker’s quarters or private living space associated with a home-based business.

Covered Upper Deck and Exterior Access

A 236-square-foot covered upper deck extends the living area outdoors. Accessible from the apartment, the deck provides space for seating, dining or enjoying surrounding views while remaining protected from direct sun and weather.

Exterior stairs provide independent access to the apartment and deck. This separation helps the living area function independently from the garage and makes the design suitable for guests, extended family members or other flexible living arrangements.

Flexible Garage, Workshop and Storage Space

The open garage level can support many different uses, including:

• Vehicle and equipment storage
• RV, boat or recreational-vehicle parking
• Woodworking or automotive projects
• Home-based business operations
• Studio, fabrication or hobby space
• Agricultural and rural-property storage
• Collector-car storage
• General workshop use

Plan 22025 works well on acreage, rural properties, mountain homesites and properties where a large shop is needed before or alongside a future primary residence. The straightforward rectangular footprint and simple roof forms also help support an efficient construction process.
