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…
  • Working with a narrow lot under 60 feet (54 feet wide)
  • Need significant workshop or storage space (1,450 square foot 3-car front-load garage)
  • Seeking an affordable compact home (1,081 square feet, 2 bedrooms)
  • Want to separate garage utility from living quarters (garage on ground level, residential entirely upstairs)
  • Interested in accessory dwelling or rental income potential (efficient 2-bedroom upper-level apartment)
! May not be the best fit if you…
  • Need more than 2 bedrooms (this plan has 2 bedrooms)
  • Want a single-story layout (this is a two-story plan with stairs to bedrooms)
  • Have a lot deeper than 39 feet (this plan requires only up to 39 feet of depth)
  • Need 2 full bathrooms (this plan has 1 full bathroom and 1 half bathroom)
  • Prefer a main-floor master suite (the bedrooms are on the second floor)

This plan tends to appeal to:

About this plan

ADU 1803-Copy 1 occupies a 54 ft width by 34 ft depth footprint, offering 1,081 sq ft of heated living area configured for efficient, vertical residential use. This two-story design prioritizes a massive 1,450 sq ft, 3-car front-load garage on the ground level, providing substantial utility for vehicle storage or a dedicated workshop space. The structural profile is defined by a steep 12:12 roof pitch and 27 ft 3 in maximum building height, utilizing 2x6 wall framing to ensure long-term structural integrity.

The first floor encompasses a 102 sq ft entry vestibule, serving as the transition point into the primary garage area. This ground-level orientation leaves the entire upper level for residential quarters, effectively separating the garage utility from the living environment. The layout is optimized to maximize square footage while maintaining a compact, footprint-conscious design suitable for smaller lots or accessory dwelling applications.

The second floor provides 979 sq ft of living space, featuring 2 bedrooms, 1 full bathroom, and 1 half bathroom. An open-concept core integrates the kitchen and a keeping family room, centered around a kitchen island that maintains clear sightlines across the primary living zone. The 9-foot ceiling height on the second level, combined with the structural volume provided by the roofline, prevents the space from feeling constrained despite the compact total floor area.

With 11-foot ceilings on the first floor and a robust 2x6 exterior wall assembly, the home demonstrates a focus on vertical volume and material durability. The combination of a 3-car garage and a fully functional 2-bedroom upper-level apartment establishes this plan as a viable solution for rental income or property expansion. The design intent focuses on high-utility spatial allocation, ensuring that both the garage and the secondary living quarters operate as distinct, efficient zones.

Key Features: 1,081 sq ft total living area, 3-car front-load garage, 2 bedrooms, 1 full bathroom, 1 half bathroom, kitchen island, open-concept floor plan, 12:12 roof pitch, 2x6 wall framing, 11-foot first-floor ceilings, 9-foot second-floor ceilings.
