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…
  • Want rental income or investment property — this is a 2-unit duplex configuration
  • Need multi-generational housing with separate units (4 bedrooms, 4 bathrooms across 2 units)
  • Working with a compact lot — the design is 40–49 ft wide and 39 ft deep
  • Want each unit to have independent laundry (first-floor laundry in each unit)
  • Prefer a single-story layout with no stairs (one-story duplex)
! May not be the best fit if you…
  • Need a single-family home — this is a 2-unit duplex
  • Want a large footprint for one household — this plan is 1,300 sq ft split between two units
  • Need 3+ bedrooms per unit — each unit has only 2 bedrooms
  • Need a garage for vehicle storage — this plan has no garage
  • Want a spacious master suite — each unit's master is compact within the efficient layout

This plan tends to appeal to:

About this plan

Modern 2-Unit Duplex with 4 Beds and 4 Baths is a single-story multi-family configuration providing 1,320 square feet of total heated living area. Designed with a 40-foot width and 33-foot depth, this structure divides into two identical 660-square-foot units, making it an efficient choice for rental income or multi-generational housing needs on compact lots.

Each unit incorporates a 2-bedroom, 2-bathroom layout centered around a keeping room that serves as the primary social core. The design prioritizes individual privacy by placing the master suite with an en-suite bathroom at the rear of each unit, while the first-floor laundry area is positioned for utility and ease of access from the living quarters.

The structural profile reaches a maximum building height of 18 ft 6 in, supported by 8-foot ceiling heights that maintain a consistent scale throughout the interior. The exterior is defined by a 6:12 roof pitch, which provides a stable and straightforward roofline for long-term maintenance. The building is constructed on a slab foundation using 2x4 wall framing, ensuring a standardized approach to site preparation and assembly.

By mirroring the floor plan across both sides, the layout maximizes the utility of the 1,320-square-foot footprint without sacrificing individual resident comfort. The side-by-side arrangement ensures that each unit benefits from independent exterior access and a logical internal flow between the kitchen, common areas, and private sleeping zones.

Key Features: 4 bedrooms, 4 bathrooms, 2-unit duplex configuration, 1,320 sq ft total area, slab foundation, 2x4 wall framing, 6:12 roof pitch, keeping room, master suite, first-floor laundry, multi-family housing.

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.
