Is this the right plan for you?

Most regret comes from buying a plan that doesn't fit your life. Skim this before you decide.

Great fit if you…
  • Need dedicated workshop or equipment storage space alongside a two-car garage
  • Working with a narrow lot or tight footprint (just 24 feet wide and 26 feet deep)
  • Want a secondary living space or rental income potential (582 sq ft with full kitchen and bathroom)
  • Seeking an accessory dwelling unit that fits common zoning requirements for outbuildings
! May not be the best fit if you…
  • Need multiple bedrooms or extensive living quarters (only 582 sq ft total living area)
  • Require a primary residence with multiple bathrooms (just 1 full bathroom)
  • Want a large family home — this plan is designed as a compact garage-apartment hybrid
  • Need significant ceiling height for RV or boat storage (8-foot ceilings throughout)

About this plan

21 036 Barndominium is a compact, two-story structure featuring a 24-foot width and 26-foot depth, optimized for properties requiring a versatile utility footprint. This design provides 582 square feet of heated living area on the first floor, alongside a 624 square foot garage that accommodates two vehicles in a front-loading configuration.

The main level houses a dedicated workspace and storage zone, supported by a full bathroom and a kitchen, allowing for multi-purpose utility. The 8-foot ceiling heights on both the first and second levels maintain a consistent interior volume, while the 14:12 and 4:12 roof pitch provides a distinct exterior profile and structural depth. The 28-foot 5-inch maximum building height ensures the structure fits within common zoning requirements for accessory buildings.

Construction relies on truss-framed roof engineering, which maximizes overhead clearance for project equipment, tool organization, or hobby storage. The internal layout is configured for efficiency, ensuring that the total footprint remains compact while providing the necessary amenities for a workshop or secondary living space.

This design serves as a specialized garage-apartment hybrid, utilizing a 2-car bay to support equipment storage or vehicle protection. The integration of a kitchen and bathroom within the 582 square foot living area establishes a self-contained environment suitable for a home office, hobby studio, or rental income potential.

Key Features: 2-car front-load garage, 582 sq ft living area, 624 sq ft garage area, 1 full bathroom, 1 kitchen, 14:12 roof pitch, 8-foot ceiling heights, truss-framed roof, accessory dwelling unit, workshop space.
