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 or limited space (just 36 ft 6 in wide and 25 ft deep)
  • Want to add rental income or guest quarters without a large footprint (fully independent 792 sq ft unit with kitchen and bathroom)
  • Need significant vehicle or storage capacity (3-car garage with 788 sq ft)
  • Seeking a starter home or downsized living space (1 bedroom, 1 bathroom, open-concept layout)
! May not be the best fit if you…
  • Need multiple bedrooms for a growing family (this plan has only 1 bedroom)
  • Want a traditional single-family home with a large footprint (792 sq ft total is compact and garage-focused)
  • Require multiple bathrooms (this plan includes only 1 full bathroom)
  • Prefer a main-floor master suite (the master suite is on the second floor only)

This plan tends to appeal to:

About this plan

56956 Fc Modern Garage Apartment provides 792 sq ft of heated living area, utilizing a compact 36 ft 6 in width and 25 ft depth footprint to maximize utility on smaller lots. This two-story design features a 3-car garage on the first level, offering 788 sq ft of vehicle or storage space, with the primary living quarters elevated to the second floor for increased privacy and separation.

The second-floor living area spans 767 sq ft, organized into an open-concept layout that integrates a kitchen, dining area, and a dedicated keeping room. The interior maintains a consistent 9 ft ceiling height, which enhances the scale of the living space and promotes natural light penetration throughout the unit. A private master suite, including a full bathroom, occupies the remainder of the upper level to ensure a self-contained living experience.

Designed with a 22 ft 7 in maximum building height and an 8:12 roof pitch, the structure maintains a clean, modern aesthetic suitable for secondary dwelling units or rental income properties. A 108 sq ft porch area provides an outdoor transition point, while the first-floor stair access ensures that the residential area remains distinct from the garage and workshop utility zones below.

The integration of a full kitchen and a complete bathroom within the 792 sq ft total ensures that this plan functions as a fully independent living unit. The building is designed to minimize site impact, making it an efficient choice for homeowners seeking to add an accessory dwelling unit or guest quarters without requiring a large foundation footprint.

Key Features: 1 bedroom, 1 bathroom, 3-car garage, 792 sq ft living area, open-concept layout, keeping room, 9 ft ceiling heights, 8:12 roof pitch, accessory dwelling unit, rental income potential.

We compared three plan sources and Archival's pricing + free design call won us over. Our builder said the construction docs were the cleanest he'd seen.
