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…
  • • You want a spacious single-story home with four bedrooms and five full bathrooms.
  • • You prefer a split-bedroom layout with a private first-floor master suite.
  • • You need a bonus room for additional recreational or flexible space.
  • • You want dedicated areas for work, exercise, and formal dining.
! May not be the best fit if you…
  • • You prefer a compact home with a smaller overall footprint.
  • • You have a narrow lot that cannot accommodate the 105′4″ width.
  • • You need all living spaces on one level without a bonus room above.
  • • You prefer a garage with front-facing vehicle access.

About this plan

A 700-square-foot covered rear porch gives this 3,978-square-foot single-story house plan a substantial outdoor extension beyond its main living area. The broad 105′4″-wide footprint accommodates four bedrooms, five full bathrooms, and a three-car side-load garage, while a separate 632-square-foot bonus room adds space above the primary level without changing the main floor's single-story arrangement.

The split-bedroom layout separates the first-floor master suite from the secondary bedrooms, establishing distinct sleeping zones within the expansive footprint. An open floor plan connects the kitchen island with the central living areas, while a formal dining room provides a separate setting for meals. The master suite includes a private bathroom and walk-in closet. A study or library creates a dedicated workspace, and the gym or flex room offers another defined area for activities beyond the main gathering spaces.

A covered front porch marks the entrance, while the larger rear porch supports outdoor dining and relaxation. The attached three-car side-load garage keeps vehicle access along the side of the house. Foundation options include a monolithic slab, crawl space, basement, or walkout basement, with 2x4 wall framing. 👉 View floor plans, photos, and pricing to get started today.
