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 on a small lot under 40 ft wide and deep (36 ft 6 in by 25 ft footprint)
  • Looking to add rental income or guest quarters without expanding your foundation (792 sq ft secondary dwelling)
  • Need vehicle and storage space alongside residential living (3-car garage plus 788 sq ft workshop area)
  • Want a private, self-contained unit with its own kitchen and bathroom
! May not be the best fit if you…
  • Need a ground-floor bedroom or living area (master suite is on the second floor only)
  • Require more than 1 bedroom (this plan has 1 bedroom only)
  • Prefer a single-story layout without stairs (two-story design with stair access required)
  • Want open yard space — most of the footprint is occupied by the garage structure

This plan tends to appeal to:

About this plan

This modern garage apartment provides 792 sq ft of heated living area on a compact 36 ft 6 in by 25 ft footprint, making efficient use of smaller lots. The two-story design stacks a 3-car garage on the first level with private residential quarters on the second floor, creating ideal separation for a secondary dwelling unit or rental income property.

The second-floor living area spans 767 sq ft and features an open-concept kitchen, dining area, and keeping room, complemented by 9 ft ceiling heights that enhance the sense of space. A private master suite with full bathroom completes the upper level, ensuring a fully self-contained living experience with all essential amenities.

The structure maintains a clean, modern aesthetic with a 22 ft 7 in maximum building height and 8:12 roof pitch, designed to minimize site impact while maximizing functionality. An 108 sq ft porch provides an outdoor transition, and the ground-floor stair access keeps the residential zone distinctly separate from the garage and workshop utility below.

JoAnne and the entire staff was extremely helpful and patient with us while we decided between 2 homes. Outstanding curb appeal and a great layout perfect for us.

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.
