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 true in-law suite for multi-generational living (dedicated in-law suite on first floor)
  • Want a first-floor master suite for accessibility and privacy (first-floor master with sitting area)
  • Seeking a home office and loft for remote work and flexible living (dedicated home office/study, loft area)
  • Need 4+ bedrooms and 4+ bathrooms for a large household (4 beds, 4 full baths, 1 half bath)
  • Have a large lot and want a 3-car garage (83 ft wide, 106 ft 8 in deep, 3-car courtyard-entry garage)
! May not be the best fit if you…
  • Want a compact footprint to keep build costs down — this is 4,309 sq ft across a large lot
  • Need a narrow lot under 70 ft wide — this design needs 83 ft of width
  • Require a single-story layout — this is a two-story design with stairs to the loft and upper bedrooms
  • Prefer a 2-car garage — this plan includes a 3-car garage (1,099 sq ft)
  • Want a simple floor plan — this design includes multiple flex spaces and specialized rooms

About this plan

4309Jz is a two-story modern house plan spanning 4,309 sq ft of total heated living space, designed for a lot width of 83 ft and a depth of 106 ft 8 in. The exterior profile reaches a maximum building height of 28 ft 2 in, utilizing an 8:12 roof pitch, complemented by 3:12 and 2:12 pitch sections that define the home's architectural character. A 55 sq ft front porch provides a primary entry point, while the 3-car courtyard-entry garage occupies 1,099 sq ft, keeping the front facade clear.

The first floor encompasses 3,307 sq ft, organized around a central open-concept core that includes a kitchen, walk-in pantry, wet bar, and a two-story great room. This level prioritizes accessibility with a primary suite featuring a sitting area and a dedicated in-law suite for multi-generational living. A mudroom and first-floor laundry room are positioned to handle high-traffic transitions, while the rear outdoor living area incorporates a built-in grill for exterior culinary use.

Occupying 1,001 sq ft, the second floor serves as a secondary living zone, housing a loft area suitable for a media room or lounge. This level also includes a flex room and a dedicated home office, providing necessary separation for remote work or study. The split-bedroom layout ensures privacy between the primary suite on the main level and the secondary bedrooms located on the upper floor.

Structural consistency is maintained throughout the home with 10-foot ceiling heights on both the first and second floors, enhancing the sense of scale in the primary living areas. This configuration supports a versatile floor plan that includes 4 bedrooms, 4 full bathrooms, and 1 half bathroom, providing a high ratio of utility for households requiring extra guest or workspace.

Key Features: 4 bedrooms, 4 full bathrooms, 1 half bathroom, 4,309 sq ft, in-law suite, home office, mudroom, 3-car courtyard-entry garage, walk-in pantry, wet bar, loft area, 10-foot ceilings, outdoor kitchen, split-bedroom layout.
