3-Story House Plan 3606 ft²: 5 Beds, 5.5 Baths, Open Floor Plan, 4-Car Garage

Plan 78451R is a 5-bedroom coastal house plan with four stories, 3606 ft² of living space and a modern, elevated profile under a hip & valley roof. It blends beach and coastal character with contemporary American design: siding covers the exterior walls, floor-to-ceiling windows open the facades, and the house measures 34'2" wide and 77'2" deep. With five full bathrooms, one half bathroom and an elevator linking the levels, this single family home is planned for comfortable year-round living, not just summer weekends.

The interior follows a reverse living layout, placing the main living areas up high where the light is brightest. An open floor plan joins a large family room with a large kitchen set at the rear of the house. A fireplace anchors the family room, so this house plan with fireplace stays just as inviting on a cool evening as on a sunny afternoon. The kitchen works around an island and a breakfast bar, giving room for cooking, quick breakfasts and conversation without anyone leaving the open space. A dedicated media room adds a separate place for movie nights and games.

The five bedrooms are arranged as split bedrooms, keeping the master suite apart from the other bedrooms for real privacy. The master suite sits on the second floor and comes with a walk-in closet. Five full baths and a half bath for guests keep busy mornings calm in a large household. Practical rooms are well covered: a mudroom catches sandy shoes and wet towels, the laundry is on the main floor, and the elevator makes this 4 story house plan easy to live in for every generation, with groceries and luggage going up without effort. A pool and a spa round out the program for relaxing at home.

Outside, the 5-bedroom coastal house plan offers generous space in the open air. Stacked porches pair a covered front porch with a covered rear porch, and a balcony, a deck and a lanai add more places to sit in the shade or follow the evening light. The drive-under garage holds four cars in a tandem arrangement, with front entry and living space upstairs. The foundation is as shown on the drawings, and the plan is also available with a crawl space, a slab, a monolithic slab, a stem wall or a basement. 2×6 exterior walls are available on request.
