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 multi-generational or dual-family living (duplex with 6 bedrooms, 6 bathrooms, two first-floor primary suites)
  • Want rental income potential (two independent units with separate primary suites)
  • Require substantial parking (4-car garage for two households)
  • Need flexible space with a full basement (872 sq ft of additional climate-controlled area)
  • Love covered outdoor entry (364 sq ft covered front porch)
! May not be the best fit if you…
  • Seeking a single-family home — this is a duplex design for two separate units
  • Have a narrow lot under 60 feet — this design requires 68 feet of width
  • Want a compact footprint (4,090 sq ft across two stories plus basement)
  • Prefer a single-story layout — this is a two-story duplex design
  • Need only 2-3 bedrooms — this plan has 6 bedrooms total across both units

About this plan

42536 Millstone Modern is a two-story duplex residence spanning 4,090 sq ft of total heated living area, optimized for multi-family use or extended family arrangements. The structure measures 68 ft in width and 65 ft in depth, requiring a lot size sufficient for its 4-car front-load garage footprint. A 364 sq ft covered front porch establishes a symmetrical facade that serves both living units equally.

The main level provides 3,084 sq ft of interior space, organized around an open-concept core that includes a kitchen island and a walk-in pantry. Each unit features a first-floor primary suite equipped with a private bathroom and a sitting area, facilitating independent living. The ground floor maintains a 9 ft ceiling height, creating a consistent vertical scale throughout the shared social areas and the private bedroom suites.

The second level encompasses 1,006 sq ft, offering additional bedrooms and bathrooms that increase the total count to six bedrooms and six full bathrooms. With 8 ft ceilings on the upper level, these rooms provide flexible utility for guest accommodations or long-term rental configurations. The inclusion of a full basement with 9 ft ceiling height allows for substantial storage or future square footage expansion.

Structural integrity is defined by a 6:12 roof pitch and a maximum building height of 25 ft 8 in. The 860 sq ft garage capacity supports four vehicles, providing dedicated parking for both units. The building configuration relies on a standardized floor plate that ensures equal distribution of space and amenities across the two separate living quarters.

Key Features: 6 bedrooms, 6 bathrooms, duplex design, first-floor primary suites, 4-car front-load garage, 364 sq ft covered front porch, 9 ft main floor ceilings, full basement, kitchen island, walk-in pantry.
