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…
  • Working with a narrow lot—this design fits a 48-foot width
  • Want a single-story layout with no stairs to climb (one-story ranch)
  • Need a master suite on the main floor for aging in place (first-floor master with walk-in closet)
  • Seeking a compact footprint to keep build costs manageable (1,248 sq ft)
  • Love covered outdoor living (covered front porch and rear deck)
! May not be the best fit if you…
  • Need 4+ bedrooms for a large family—this plan has 3 bedrooms
  • Want a two-story design to maximize lot usage—this is single-story only
  • Require a garage—this plan has no garage bays
  • Prefer an open kitchen without a defined dining area—the layout includes a separate dining zone

This plan tends to appeal to:

About this plan

Cosby House Plan occupies a compact 1,248 square foot footprint, utilizing a traditional ranch-style configuration that emphasizes efficiency and single-level accessibility. Measuring 48 feet in width and 42 feet in depth, this residence is engineered for smaller lots while maintaining a distinct architectural profile defined by an 8:12 roof pitch and a maximum building height of 19 feet 10 inches.

The interior architecture centers on an open-concept family room, where the 8-foot ceiling height provides a consistent volume that maximizes the perceived scale of the living area. A centralized fireplace serves as the primary focal point, flanked by a kitchen and dining area that offers direct circulation to the 126-square-foot covered front porch and the 100-square-foot rear deck, facilitating indoor-outdoor utility.

A split-bedroom layout defines the private zones of the home, separating the primary suite from two secondary bedrooms to ensure acoustic and spatial privacy. The primary suite includes a dedicated walk-in closet and a private bathroom, while the remaining bedrooms share access to a secondary full bathroom and a half bathroom, making this arrangement suitable for guests or a home office.

Structural integrity is provided through standard stick-framed construction, supported by a crawl space foundation. This design integrates a first-floor laundry area into the floor plan to minimize transit between living and utility zones, maintaining a streamlined circulation path throughout the 1,248 square feet of heated living area.

Key Features: 3 bedrooms, 2 full bathrooms, 1 half bathroom, split-bedroom layout, 8-foot ceiling height, 8:12 roof pitch, covered front porch, rear deck, crawl space foundation, fireplace, first-floor laundry.

We compared three plan sources and Archival's pricing + free design call won us over. Our builder said the construction docs were the cleanest he'd seen.
