Plan 47749R is a 4-bedroom coastal house plan with four stories, 3291 ft² of living space and a roofline that pairs gable and hip & valley forms, the ridge running parallel to the street. Wrapped in siding, this beach-style American single family home has an elevated, narrow shape and measures 45'0" wide and 63'4" deep. Four full bathrooms and one half bath serve the family, and an elevator makes moving between floors easy on any day, with groceries or luggage in hand.
The main living level follows an open floor plan built around a center kitchen. A large island with a breakfast bar faces the shared space, so whoever is cooking stays part of the conversation, and a walk-in pantry keeps supplies out of sight. The family room is anchored by a fireplace, a clear draw for anyone looking for a house plan with fireplace, and a sitting area adds a quieter spot for reading or morning coffee. For work and entertainment, the home includes a dedicated home office and a media room, which keep screens and calls away from the main gathering space.
The main floor master gives the owners a private retreat with a walk-in closet, while the split bedrooms place the remaining rooms apart from the primary suite for better privacy. Two of the secondary bedrooms share a Jack & Jill bath, and with four full baths in total, mornings run without a line at the door. Laundry on the main floor saves trips up and down, a mudroom catches sandy shoes and wet towels at the entry, and generous storage handles beach gear and seasonal items.
Outside, stacked porches give the facade its coastal character and offer outdoor rooms on more than one level. There is a covered front porch, a covered rear porch, a screened porch for evenings without insects, a deck, a lanai and a balcony, so every part of the day has its own place in the open air. The drive under garage holds four cars in a tandem arrangement with front entry, tucked beneath the living floors of this elevated house. 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. Exterior wall framing is as shown, with 2×6 exterior walls available on request.
