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…
  • Building an accessory dwelling unit or rental property on a tight lot (compact 38-by-28-foot footprint)
  • Need flexible garage and workshop space for vehicles or equipment (3-car garage)
  • Want laundry access directly from the bedroom for convenience (laundry access from master closet)
  • Planning for a single occupant or couple without children (1 bedroom, 1 bathroom)
! May not be the best fit if you…
  • Need multiple bedrooms for a growing family — this plan has only 1 bedroom
  • Require a main-floor master suite — the bedroom is on the second floor above the garage
  • Want a spacious home — 938 sq ft is designed for efficient, compact living
  • Prefer a traditional single-family layout — this is a stacked carriage house design

This plan tends to appeal to:

About this plan

Three Car Garage Apartment spans 938 square feet of heated living area, utilizing a stacked design that elevates the residence above a 3-car garage. With a footprint measuring 38 ft in width and 28 ft in depth, this carriage house plan provides a compact yet efficient solution for accessory dwelling units or rental income properties. The structure is defined by its 12:12 roof pitch, which creates a distinct architectural profile while maintaining a consistent 8-foot ceiling height across the second-floor living quarters.

The second-level floor plan organizes the living space around an open-concept core, integrating a kitchen island with seating that maintains sightlines into the family room. A fireplace serves as a central element within the living area, while the bedroom layout includes direct access to the laundry, streamlining household tasks. The 938-square-foot interior is designed for single-occupant or couple living, prioritizing clear circulation between the kitchen, dining, and sleeping zones.

Construction specifications include 2x6 exterior wall framing to accommodate modern insulation requirements and structural integrity. The 8-foot ceiling heights throughout the second floor ensure a standard, comfortable interior volume, while the ground floor is dedicated entirely to the 938-square-foot garage capacity. This configuration allows for three vehicle bays, providing substantial storage or workshop space beneath the residential unit.

The integration of the garage and living levels maximizes site utility, making this design suitable for lots where building footprint must remain minimal. The 12:12 roof slope contributes to the vertical presence of the building, ensuring the structure complements existing primary residences while offering a self-contained, functional living environment.

Key Features: 3-car garage, 938 sq ft living area, 1 bedroom, 1 bathroom, carriage house design, 12:12 roof pitch, 8-foot ceiling height, 2x6 wall framing, kitchen island, fireplace, laundry access from master closet.

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.
