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 4-car garage for vehicles, equipment, or workshop space — 1,433 square feet with 10-foot ceilings
  • Want an ADU or guest suite — 971 square feet of self-contained upper-level living
  • Have multi-generational living needs — separate residential unit above the garage
  • Seek rental income potential — complete apartment with master suite and flexible room
  • Love a compact footprint — 43-by-50 feet with dual functionality
! May not be the best fit if you…
  • Need multiple bedrooms — this plan has only 1 bedroom
  • Want main-floor living — all residential space is on the second floor
  • Prefer a traditional home design — this is a garage-focused structure
  • Need a large living area — 971 square feet upstairs is modest for a primary residence

This plan tends to appeal to:

About this plan

ADU-Style Garage with Upper-Level Living

This Garage plan combines a massive 4-car garage with 1,038 square feet of upper-level living, creating a hybrid structure ideal for property owners needing both vehicle storage and a self-contained apartment. The 43-by-50-foot footprint and 26-foot-7-inch height deliver 1,433 square feet of garage space on the ground floor, with 971 square feet of residential quarters above.

The main level is dedicated to utility: a 4-car garage with 10-foot ceilings for tall vehicles or equipment, a half bathroom, and a 329-square-foot side porch for circulation. This setup accommodates serious vehicle collections, workshop needs, or commercial equipment storage without compromising the residential zone.

The second floor is a complete living unit: a master suite with full bathroom and walk-in closet, plus a flexible room for a home office, hobby studio, or media area. Nine-foot ceilings create an open feel, while the slab foundation and efficient layout keep construction straightforward. This design works as an ADU, guest suite, rental unit, or multi-generational living space.

  • 4-car garage with 1,433 square feet and 10-foot ceilings for large vehicles
  • Second-floor master suite with walk-in closet and full bathroom
  • Flexible room upstairs for home office, studio, or media use
  • Self-contained upper-level living — ideal for ADU or rental 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.
