Plan 89404R is a 4-bedroom coastal house plan that rises over four stories, offering 2295 ft² of living space beneath a hip and valley roof, with a beach-style elevation finished in siding. This elevated single-family home measures 44'0" wide and 50'4" deep and follows the American coastal tradition: the living floors sit above a drive-under garage, and an elevator links every level, so the height of the house never becomes a burden for groceries, guests or older family members.
The main living level is an open floor plan arranged around a large family room with a fireplace and a center kitchen set toward the rear of the house. The large kitchen is built for real family use, with an island, a breakfast bar for quick meals, a breakfast nook for slower ones, and a walk-in pantry that keeps the counters clear. Large windows, floor-to-ceiling glass and a corner window carry daylight deep into the rooms, and on cool evenings the fireplace becomes the natural place to gather. A sitting area, a media room for movie nights and a home office complete the spaces for everyday life and work.
The master suite is on the second floor and includes a walk-in closet, while the split bedrooms layout keeps it apart from the other three bedrooms for privacy. Two of the secondary bedrooms share a Jack & Jill bath, and with five full bathrooms and a half bath in total, mornings run without a line at the door. The laundry is also on the second floor, close to the bedrooms, and a separate utility room keeps the mechanical side of the house out of sight. A defined entry receives guests and gives the arrival a sense of order.
Outside, this 2-car garage house plan places the drive-under garage at ground level, with both front entry and rear entry listed among its features. Stacked porches give several levels their own outdoor rooms, joined by a covered rear porch, a deck, a balcony and a lanai for shaded afternoons in the fresh air. The house stands on the foundation as shown in the drawings; a crawl space, slab, monolithic slab, stem wall or basement foundation is also available on request, as are 2×6 exterior walls.
