3-Story House Plan 4116 ft²: 4 Beds, Home Office, 3.5 Baths, Open Floor Plan, 4-Car Garage

Plan 24376R is a 4-bedroom elevated coastal house plan spread across four stories, with 4116 ft² of living space under a hip & valley roof and siding on the exterior walls. Coastal, contemporary and modern lines come together with an American sense of proportion in this single family home, which measures 68'4" wide and 64'4" deep. Three full bathrooms, one half bathroom and an elevator that links every level make the house easy to live in for a large household, for guests and for every generation of the family.

The heart of the home follows an open floor plan, where a large family room flows into a large kitchen at the rear of the house. The kitchen has an island, a breakfast bar for quick meals, a breakfast nook for slower mornings and a walk-in pantry that keeps supplies out of sight. Floor-to-ceiling windows, panoramic windows and large windows draw daylight deep into the rooms and frame the view from the elevated floors. The split level layout gives each zone its own character while keeping the living spaces connected, and a media room offers a separate place for movie nights.

The sleeping quarters are arranged as split bedrooms, with two master suites: one main floor master and one second floor master, so a couple and a parent or an older child can each have a private retreat. A Jack & Jill bath serves two of the secondary bedrooms, and an in-law suite gives visiting relatives their own comfortable space. A home office, an exercise room and plenty of storage cover work and daily routines. The mudroom catches coats and shoes at the door, and laundry on the main floor, set in a utility room, keeps the chores close at hand.

Outside, a wraparound porch and stacked porches add outdoor living on more than one level, while a covered rear porch, a lanai and a balcony offer shade and fresh air on warm evenings. The drive-under, front entry garage holds 4 cars and is a garage with upstairs space, tucked beneath the raised living floors. The foundation is built as shown in the drawings; the plan is also available with a crawl space, a slab, a monolithic slab, a stem wall or a basement, and with 2×6 exterior walls on request. For anyone looking for a 4-story house plan with an elevator and two master suites, this design offers room, light and flexibility in equal measure.
