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…
  • Have a large family or frequently host extended family (4 bedrooms, 4.5 baths)
  • Need a second-floor master suite with a sitting area and walk-in closet for privacy and luxury
  • Want a chef kitchen with walk-in pantry and island (kitchen island, walk-in pantry, eating bar)
  • Need space for 3+ vehicles (3-car garage)
  • Working with a larger lot — the design requires 55 ft 6 in width and 79 ft depth
! May not be the best fit if you…
  • Prefer a single-level layout — this is a two-story plan with stairs to the bedrooms
  • Want a main-floor master suite — the master is on the second floor
  • Have a narrow lot under 50 ft — this design needs 55 ft 6 in of width
  • Want to minimize build costs — at 4,370 sq ft across two floors, this is a substantial investment
  • Need a compact footprint — the 79-ft depth is substantial

About this plan

New American House 4 Beds 4 5 Baths Plan provides 4,370 square feet of heated living space, optimized for a 55-foot 6-inch width and 79-foot depth lot. This two-story residence utilizes a high-pitch 12:12 roofline to create a distinct architectural profile while incorporating a 3-car garage (1,124 sq ft) that maintains a clean street-side elevation.

The main level encompasses 1,929 square feet, anchored by an open-concept core that connects the kitchen, breakfast area, and great room. The kitchen features a central island with an integrated eating bar and a dedicated walk-in pantry, ensuring efficient circulation. A first-floor laundry room provides immediate access from the garage, while a 110-square-foot front porch and a 523-square-foot rear patio extend the usable footprint to the exterior.

The second floor contains 2,441 square feet, prioritizing privacy with a sprawling master suite that includes a sitting area and walk-in closet. The upper level is rounded out by additional bedrooms with private bathroom access and a central loft, which provides flexible square footage for media or study use. With 10-foot ceilings on the main level and 9-foot ceilings on the second level, the interior volume emphasizes vertical space.

Structural integrity is supported by a 34-foot 6-inch maximum building height and an 8:12 roof pitch, contributing to a substantial vertical presence. The total footprint, including the 633 square feet of combined porch areas and a 115-square-foot deck, provides a comprehensive layout for large-scale family living and multi-generational needs.

Key Features: 4,370 sq ft total living area, 4 bedrooms, 4 full bathrooms, 1 half bathroom, 3-car garage, second-floor master suite with sitting area, central loft, open-concept kitchen with island, walk-in pantry, first-floor laundry, 12:12 roof pitch, covered front porch.
