2-Story House Plan 1706 ft²: 4 Beds, Home Office, 4 Baths, Open Floor Plan, 1-Car Garage

Plan 78159R is a 4-bedroom 3-story house plan with coastal and Craftsman character, offering 1706 ft² beneath a hip & valley roof and finished in siding. Contemporary lines and a light modern farmhouse touch give this single-family home a relaxed, beach-inspired look that feels at ease by the water or in a quiet suburb. The house measures 33'4" wide and 62'8" deep, and within that footprint it fits four bedrooms, four full bathrooms, a home office and an ADU, a rare combination for a coastal house plan.

The everyday living spaces follow an open floor plan, so the family room, the dining area and the kitchen read as one connected space. Vaulted ceilings lift the family room, where a fireplace becomes the natural gathering point on cool evenings. The rear kitchen is placed at the back of the house, keeping the cooking zone out of the line of the front entry while staying open to the living area. A breakfast nook beside it handles quick morning coffee, homework and casual meals, leaving more formal dinners to the main table. For anyone who works from home, the home office offers a door to close and a quiet corner away from the bustle.

The main floor master makes single-level living possible for the owners, with a walk-in closet and its own full bathroom. Split bedrooms keep the master suite apart from the other three bedrooms, which gives parents and children or guests real privacy. With four full bathrooms and no half baths, every bedroom can have convenient access to a complete bath. The ADU adds flexible accommodation for visiting relatives, an adult child, a caregiver or long-stay guests, while a mudroom catches sandy shoes, wet coats and beach bags before they reach the living areas.

Outside, a portico shelters the front entry and sets a welcoming tone, and a screened porch extends the living space outdoors, ideal for summer dinners without the insects. This house plan with a detached garage includes a one-car garage set apart from the main house, keeping noise and fumes away from the bedrooms. The foundation is as shown on the plans, and the design is also available with a crawl space, slab, monolithic slab, stem wall or basement foundation. 2×6 exterior walls can be requested as well. As a 4-bedroom 3-story house plan with a fireplace, an ADU and a screened porch, plan 78159R balances family life, guests and work under one roof.
