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…
  • Want a single-story layout with no stairs (one-story design, 3,599 sq ft on main floor)
  • Need a chef kitchen with a walk-in pantry and butler's pantry
  • Work from home and need a dedicated home office
  • Frequently entertain—852 sq ft of covered porch space plus open-concept living
  • Have a large family or multi-generational household (4 bedrooms, 4.5 baths)
! May not be the best fit if you…
  • Have a narrow lot—this design needs 89 feet 6 inches of width
  • Want a compact footprint to keep build costs down (3,599 sq ft is a sprawling design)
  • Need a 3+ car garage—this plan has a 2-car garage
  • Prefer a two-story layout—this is a single-story plan

About this plan

Spanning 3,599 sq ft of heated living area, the A144 B2 Davis 2 occupies a footprint measuring 89 ft 6 in in width and 82 ft in depth. This one-story residence is framed with 2x4 exterior walls and finished with a stucco facade, presenting a 28 ft 3 in maximum building height and an 8:12 roof pitch that defines its structural profile.

The interior architecture centers on an open-concept core where the kitchen, equipped with a central island, walk-in pantry, and butler’s pantry, maintains direct sightlines to the breakfast area and main living zones. Nine-foot ceilings throughout this level enhance the distribution of natural light across the 3,599 sq ft floor plate. A dedicated home office provides a quiet zone for professional tasks, while the inclusion of a media room adds flexibility for entertainment and leisure.

The bedroom configuration utilizes a split-layout strategy to increase privacy, with the primary owner’s suite featuring dual his and hers closets. Secondary bedrooms are integrated with a Jack and Jill bathroom, ensuring efficient access and shared utility. A mudroom is located near the garage entry to manage transition zones and household storage requirements.

Practical utility is addressed through a 676 sq ft rear-load 2-car garage and 852 sq ft of covered porch space, which extends the usable area for exterior activities. The plan also incorporates 676 sq ft of dedicated storage, ensuring that the total area of 5,127 sq ft is utilized for both living and household maintenance needs.

Key Features: 4 bedrooms, 4 full bathrooms, 1 half bathroom, one-story configuration, open-concept kitchen, butler’s pantry, walk-in pantry, home office, media room, Jack and Jill bathroom, mudroom, rear-load 2-car garage, covered porch.
