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…
  • Managing a multi-family or rental property — duplex configuration with 6 bedrooms and 4 full baths (two identical 3-bedroom, 2-bath units)
  • Need flexible home office space — each unit includes a dedicated home office on the main floor
  • Want open-concept entertaining per unit — keeping room and kitchen flow together around a central island (1,376 sq ft per unit)
  • Require second-floor laundry — each unit has laundry upstairs near the bedrooms
  • Seeking a larger duplex footprint — 48 ft width and 42 ft depth provide substantial floor area (3,056 sq ft total)
! May not be the best fit if you…
  • Want a single-family home — this is a duplex with two attached units
  • Need a large first-floor master suite — each unit's primary suite is located on the second floor
  • Require a garage larger than 1 car per unit — each unit has only a 1-car garage

About this plan

Duplex Design for Multi-Unit Living or Investment

The 29454 Flacco Modern Twin is a two-story duplex providing 3,056 sq ft total (1,528 sq ft per unit) on a 48 ft × 42 ft footprint. Each unit features a 1-car front-load garage and covered front porch, establishing distinct residential profiles while maximizing shared-wall efficiency. The home reaches 28 ft 8 in in height and is built on a slab foundation.

Each unit's main floor (1,376 sq ft per unit) centers on an open keeping room connected to a kitchen with central island, complemented by a dedicated home office for remote work. A half bath serves the primary zones, and 9 ft ceilings enhance interior volume. Upstairs, 960 sq ft per unit houses three bedrooms including a primary suite with ensuite bath and walk-in closet, plus second-floor laundry, loft space, and additional storage. The duplex design includes a shared walk-in pantry and storage zones to maximize utility.

With four full bathrooms and two half baths total across the duplex, this plan is configured for multi-family occupancy, long-term rentals, or investment properties. The stacked layout and 8 ft upper-level ceilings support both residential comfort and efficient property management.

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.
