3-Story House Plan 5200 ft²: 3 Beds, Home Office, 3 Baths, Open Floor Plan, 4-Car Garage

Plan 15834R is a 3-bedroom coastal house plan for an elevated, four-story single-family home of 5200 ft², finished in siding and crowned by a gable roof with its ridge set perpendicular to the street. Beach and classic American touches shape the facade, where stacked porches rise one above another, and the house measures 37'0" wide and 54'0" deep. The layout follows the reverse living idea: the main living rooms sit on an upper level, above the ground-floor garage, and an elevator connects every floor of this 4 story house plan, so groceries, luggage and guests move up without effort.

The heart of the home is an open floor plan that joins a large family room and a large kitchen into one generous space under vaulted ceilings. The kitchen is placed at the front of the house and gives the cook a central island and a breakfast bar for quick meals, homework or a coffee while the rest of the family gathers nearby. With no walls between cooking, dining and relaxing, the whole level feels like one room on long summer evenings, yet each zone keeps its own purpose. A dedicated home office offers a quiet corner for remote work away from the bustle.

The master suite shares the main living floor, while a split bedroom arrangement places it apart from the two other bedrooms for real privacy. Three full bathrooms mean no one waits in the morning, a comfort for families and visiting friends alike. Practical needs are handled on the lower level, where the laundry sits close to the garage, and additional storage keeps beach gear, seasonal items and everyday clutter out of sight.

Outside, the drive-under garage holds four cars and offers both front entry and rear entry, a flexible arrangement for many driveway layouts. A covered front porch welcomes visitors, a covered rear porch and a deck extend the living space outdoors, and a lanai adds a sheltered spot for shaded afternoons. The foundation is built as shown in the plans, and the design is also available with a crawl space, slab, monolithic slab, stem wall or basement foundation. The exterior walls are framed as shown, with 2×6 exterior walls available on request for those who want extra thickness in the shell.
