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 an accessory dwelling unit for extended family or rental income (754 sq ft independent living unit with full kitchen and bath)
  • Want workshop or hobby space with vehicle storage (900 sq ft garage with dedicated workshop zone and 9-foot ceilings)
  • Working with a compact lot (34 feet wide, 30 feet deep)
  • Want to add density without building a second primary residence (carriage house configuration)
  • Need tall ceiling clearance for equipment or classic vehicles (9-foot first-floor ceilings)
! May not be the best fit if you…
  • Need multiple bedrooms for a family (this plan has only 1 bedroom)
  • Want a primary residence rather than guest or rental unit (designed as ADU or carriage house)
  • Need a large footprint (compact 34 by 30 feet design)
  • Prefer a traditional house plan over a garage-based structure (this is a garage apartment)

This plan tends to appeal to:

About this plan

Two Car Garage Studio occupies a 34-foot by 30-foot footprint, providing a highly efficient structure that combines vehicle storage with an independent living unit above. This plan is engineered for properties requiring a compact ADU or carriage house, delivering 754 square feet of heated living space situated over a substantial 900 square foot ground-level garage. The 12:12 roof pitch creates a steep, classic profile, while the 9-foot ceiling heights on the first floor ensure vertical clearance for workshop equipment or storage utility.

The ground level is dedicated to a 2-car garage capacity, organized to support both vehicle parking and a dedicated workshop zone. By centralizing the utility and storage footprint on the first floor, the design reserves the entire upper level for residential use. This configuration is optimized for homeowners seeking to add density to their lot without compromising the integrity of the primary residence, as the layout separates industrial-style storage from the climate-controlled living quarters.

The 754-square-foot upper level features a single-bedroom layout, complete with a full bathroom and an integrated kitchenette, dining, and living area. This arrangement serves as a self-contained unit, suitable for long-term guests, extended family, or rental income generation. The separation of the sleeping area from the open-concept living zone provides a clear distinction between active and resting spaces within the compact floor plate.

Construction technicalities include a 12:12 roof pitch, which contributes to the building's distinct aesthetic and allows for increased overhead volume within the upper-level living quarters. The 9-foot first-floor ceilings accommodate tall vehicles and workbench installations, making the structure a dual-purpose asset for hobbyists and homeowners alike. The footprint is designed for straightforward installation, prioritizing structural utility and site-specific adaptability.

Key Features: 1 bedroom, 1 full bathroom, 754 sq ft heated living area, 900 sq ft 2-car garage, workshop space, 12:12 roof pitch, 9-foot ceiling height, 34-foot width, 30-foot depth, ADU configuration.
