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…
  • Planning multi-generational living — includes a 1,280 sf in-law suite with separate entrance
  • Need a single-story layout with no stairs (one-story ranch spanning 5,505 sf)
  • Want dual master suites for flexibility (two full primary suites with dual bathrooms)
  • Working with a large lot over 110 feet — plan requires 117 ft width and 185 ft depth
! May not be the best fit if you…
  • Need more than 4 primary bedrooms — main house has 4 bedrooms (in-law suite is separate)
  • Working with a standard residential lot under 110 feet — this design needs 117 ft width
  • Want a compact footprint to minimize build costs (5,505 sf single-story requires expansive lot)

About this plan

Sprawling Single-Story Estate with In-Law Suite & Dual Master Suites

This sprawling single-story estate spans 5,505 square feet on a spacious lot measuring 117 feet wide and 185 feet deep. The design features 4 primary bedrooms, 5 full bathrooms, and 1 half bathroom, with the main floor encompassing 3,624 square feet organized around an open-concept core and central courtyard. The kitchen includes a large island and walk-in pantry, complemented by a wet bar, dedicated home office with storage (601 sf), and first-floor primary suite with private master bath.

A standout feature is the 1,280-square-foot bonus in-law apartment with a separate entrance, providing an independent living zone for multigenerational households. The home includes dual master suites, split-bedroom configuration for privacy, and 10-foot ceiling heights throughout. Outdoor living spans 383 square feet of combined porch area, including a 277-square-foot rear porch that extends the living environment.

The 3-car garage (1,016 sf) provides substantial vehicle and workshop space. At a maximum building height of just 24 feet with an 8:12 roof pitch, the sprawling layout maintains a clean profile despite its expansive footprint. This design prioritizes multi-generational flexibility, professional workspace, and high-capacity residential utility on an acreage or estate-scale property.
