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…
  • Have a large family or frequently host extended family (5 bedrooms, 5 full baths)
  • Love outdoor entertaining with a dedicated outdoor kitchen (outdoor kitchen on covered back porch)
  • Building on a coastal lot — the design is built on pilings for storm resilience
  • Need a second-floor master suite for privacy (master suite on second floor)
  • Want a home office plus formal dining for work and entertaining (home office/study, formal dining room)
! May not be the best fit if you…
  • Have a narrow lot under 50 feet wide — this design needs 50 to 59 feet of width
  • Want a single-story layout — this is a two-story plan with stairs
  • Need a 3-car garage — this design has a 2-car garage
  • Prefer a compact footprint to minimize build costs (4,435 sq ft across two stories)

This plan tends to appeal to:

About this plan

At 4,435 sq ft, the Marsh Harbour is a magnificent luxury residence that redefines traditional elegance with its grand five-bedroom layout and refined interior comforts. This design is built for large-scale family living and grand entertaining, featuring an expansive open-concept core that connects the primary living zones in a bright and airy environment.

The interior experience begins in a grand foyer that opens into a vaulted family room, connecting naturally to a gourmet kitchen and a formal dining room for special occasions. The second-floor owner's suite serves as a private sanctuary with a generous walk-in closet and a luxurious master bath, while a dedicated home office provides a peaceful retreat away from the home's social areas.

Functional details like ample storage, a three-car garage, and multiple bathroom suites ensure that every member of the household enjoys maximum comfort and privacy. Built with robust stick framing on a sturdy foundation, the Marsh Harbour is a substantial and well-crafted home. View floor plans, photos, and pricing to get started today.
