Plan 90915R is a 4-bedroom coastal house plan that rises four stories on an elevated design, offering 6164 ft² beneath a hip and valley roof. The Beach, Coastal and American styling shows in exterior walls of stucco paired with shakes/shingles, while the hip roof sets its ridge parallel to the street. The single-family home measures 80'1" wide and 65'0" deep, and an elevator connects every level, so the upper floors stay easy to reach for guests and grandparents alike.
Through the entry, the open floor plan unfolds around a large family room with a fireplace and a sitting area beside it. The space is open to below, and floor-to-ceiling windows with wide panoramic glass draw the view straight into the room. The large kitchen sits at the rear of the house and works as its true center: an island, a breakfast bar for quick meals and a breakfast nook for slower weekend mornings, plus a walk-in pantry that keeps the counters clear. A media room gives the family a place for movie nights, and a bonus/flex room adapts to a home office, a playroom or a guest space as the years change.
The four bedrooms follow a split layout for privacy. This is a house plan with two master suites: one on the main floor and a second on the upper floor, each finished with a walk-in closet, which suits multigenerational living or long visits from family. Five full bathrooms and a half bath mean no one waits in the morning. Laundry on the main floor keeps everyday chores close to the kitchen and the living areas.
Outside, stacked porches give the home its relaxed coastal character, with a covered front porch, a covered rear porch, a balcony and a lanai for warm evenings outdoors. Beneath the living levels, a drive-under, front-entry garage holds four cars in a tandem arrangement, with living space above it. The foundation is built as shown in the drawings; the plan is also available with a crawl space, slab, monolithic slab, stem wall or basement foundation, and 2×6 exterior walls can be specified on request.
