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…
  • Frequently host extended family or guests (dedicated first-floor guest suite with full bathroom)
  • Want a main-floor primary suite with sitting area (master on first floor with his-and-hers closets)
  • Work from home and need a dedicated office (home office on main level)
  • Require substantial vehicle storage (3-car side-load garage)
  • Want a dramatic focal point in the home (two-story grand room with open sightlines)
  • Need multi-generational living space (guest suite separate from primary bedrooms)
! May not be the best fit if you…
  • Working with a narrow lot — this design needs 89 feet of width
  • Want a single-story layout with no stairs (two-story plan with upper-level bedrooms and loft)
  • Prefer a compact footprint to keep build costs down (4,628 sq ft across two floors)
  • Need a modest home for a small household (designed for 4 bedrooms and multi-generational use)

About this plan

Contemporary LG185 is a sprawling 4,628 sq ft two-story residence engineered for estate-sized lots with an 89 ft width and 80 ft 6 in depth. The side-load 3-car garage, totaling 834 sq ft, preserves the architectural symmetry of the front elevation while providing substantial vehicle storage. An 8:12 roof pitch defines the exterior profile, reaching a maximum building height of 34 ft 5 in to create an imposing presence on the landscape.

The interior centers on a grand room featuring a two-story volume that serves as the primary visual axis, enhanced by 10 ft ceilings on the first floor. This open-concept core integrates a large center island kitchen and a walk-in pantry, providing direct sightlines across the main living level. A dedicated home office and a private guest suite are positioned on the main floor, ensuring clear separation between formal work zones and residential quarters.

Occupying 3,357 sq ft of the total living area, the first floor includes a primary suite equipped with a sitting area and his-and-hers walk-in closets. The 1,271 sq ft second floor houses additional bedrooms, a loft, and a game room, with 9 ft ceiling heights that maintain a sense of vertical volume. This level overlooks the central grand room, maintaining a consistent connection to the primary social zone below.

Practical utility is managed through 533 sq ft of covered porch space, which extends the livable footprint into the outdoor environment. The structural layout utilizes a 4-bedroom, 4-full-bath, and 1-half-bath configuration, catering to multi-generational requirements and large-scale occupancy. The floor plan prioritizes spatial efficiency by segregating high-traffic common areas from private sleeping retreats.

Key Features: 4 bedrooms, 4.5 bathrooms, side-load 3-car garage, two-story grand room, first-floor primary suite, sitting area, home office, walk-in pantry, loft, game room, covered porch, 8:12 roof pitch.
