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 a guest house or rental unit on your property — 905 sq ft one-bedroom apartment with full kitchen and bath
  • Want a workshop or room for 3+ vehicles — the 1,064 sq ft three-bay garage provides ample space
  • Working with a narrow lot — the design is just 39 ft wide and 39 ft deep
  • Need a compact footprint to keep build costs down — 905 sq ft total living space
! May not be the best fit if you…
  • Need multiple bedrooms for a growing family — this plan has only 1 bedroom
  • Want a single-story layout with no stairs — this is a two-story design with living quarters upstairs
  • Need 2+ bathrooms — this plan has only 1 full bath

About this plan

The Alexis is a charming 905 sq ft garage apartment that offers a cozy and efficient one-bedroom living haven perched above a spacious three-bay garage. This colonial-style carriage house is an ideal solution for an accessory dwelling unit, providing a private and well-appointed residence that doesn't compromise on utility or garage space.

The second-floor living quarters are designed with an open and bright layout, where the kitchen and living areas flow naturally together. The owner's suite is located on this upper level, featuring a walk-in closet and easy access to the full bath, creating a complete and comfortable sanctuary away from the ground-floor activity. Below, the 1,064 sq ft garage provides three front-loading bays that are perfect for vehicle storage, a workshop, or additional property equipment.

Constructed on a reliable slab foundation with 2x4 wall framing, the Alexis is built for long-lasting functionality and comfort. The classic traditional exterior ensures this small home has timeless curb appeal that fits perfectly onto any modern suburban or rural lot.

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.
