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…
  • Multi-generational families or those planning to host extended family long-term (1,280 sq ft in-law suite with separate entrance and full kitchen)
  • Need substantial workspace for a home office, studio, or hobby (601 sq ft dedicated office and storage suite)
  • Frequently entertain large groups (5,505 sq ft, wet bar, open-concept kitchen and living areas, 277 sq ft rear porch)
  • Require significant vehicle or equipment storage (3-car garage with 1,016 sq ft)
  • Working with a spacious, wide lot—the design needs 117 ft of width and 185 ft of depth
  • Prefer single-level living with no stairs (one-story ranch layout)
! May not be the best fit if you…
  • Have a narrow or compact lot—this plan requires over 110 ft of width and depth
  • Want to minimize build costs—5,505 sq ft is a large footprint with substantial square footage
  • Need a modest, downsized home—this estate plan is designed for expansive living
  • Prefer a simple, straightforward layout—the dual master suites and in-law wing add complexity

About this plan

5505Jz is a sprawling estate encompassing 5,505 sq ft of total heated living space, designed to accommodate large-scale residential needs on a spacious 117 ft wide by 185 ft deep footprint. The architecture prioritizes a sprawling single-level configuration, anchored by a central courtyard that provides natural light penetration to the interior living zones. The structural profile reaches a maximum building height of 24 ft, featuring an 8:12 roof pitch that provides a substantial presence on the lot.

The 3,624 sq ft main floor organizes its spatial hierarchy around an open-concept core, where the kitchen features a large island and a dedicated walk-in pantry. A wet bar serves the primary living area, maintaining direct sightlines to the surrounding rooms. The layout includes five full bathrooms and one half-bathroom, with a split-bedroom arrangement that creates privacy for the dual primary suites. A dedicated 601 sq ft office/storage area is incorporated into the structure to support professional and organizational requirements.

A notable feature of this residence is the 1,280 sq ft bonus apartment, which functions as an independent in-law wing with a separate entrance. This secondary living space provides a distinct, flexible zone while maintaining architectural continuity with the main house. The 10 ft ceiling heights throughout the main level contribute to the sense of volume, while the 383 sq ft of combined porch area, including a 277 sq ft rear porch, extends the living environment outdoors.

The structural design includes a 3-car garage with 1,016 sq ft of space, ensuring significant utility for vehicle storage and workshop capacity. The integration of these spaces alongside the dedicated office and storage zones demonstrates a commitment to high-capacity residential utility. The home is engineered for complex property sites that require a wide, estate-style layout with multi-generational living capabilities.

Key Features: 5,505 sq ft total area, 4 bedrooms, 5 full bathrooms, dual master suites, in-law wing with private entrance, 3-car garage, 10 ft ceiling heights, office and storage suite, walk-in pantry, wet bar, 8:12 roof pitch, 117 ft building width.
