Plan 73643R is a 4-bedroom 2-story house plan with modern farmhouse character, offering 4579 ft² of living space beneath a hip & valley roof punctuated by dormers and finished in siding. Drawing on Country, New American and American traditions, this single family home measures 65'5" wide and 85'5" deep and pairs three full bathrooms and a half bath with a 3-car garage, a balanced layout for a growing family that wants room to spread out.
The heart of the house is an open floor plan built around a large family room with a fireplace, where vaulted ceilings lift the space and give it an airy, generous feel. The large kitchen sits at the rear of the home and is made for both everyday meals and entertaining: a central island anchors the work zone, a breakfast bar invites quick conversations over coffee, and a separate breakfast nook offers a relaxed spot for family breakfasts as the morning sun comes in. A walk-in pantry keeps groceries and small appliances organized and out of sight, so the open sightlines stay clean.
Privacy is handled with a split bedrooms arrangement. The main floor master is set apart from the other bedrooms and includes a walk-in closet, giving the owners a quiet retreat on the same level as the living spaces. Two of the secondary bedrooms share a Jack & Jill bath, a practical choice for siblings, and with three full bathrooms in total, morning routines run smoothly. Laundry on the main floor saves trips up and down the stairs, dedicated storage helps with seasonal items, and a bonus room above the garage works as a flex space for a playroom, home office, guest quarters or hobby room.
Outside, a covered front porch welcomes guests and sets a friendly tone for the street view, while a screened porch and a deck extend everyday life outdoors on warm evenings. The 3-car garage extends forward and is reached through a courtyard entry, which keeps the garage doors from dominating the facade and creates a pleasant courtyard at the front of the 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 on request. 2×6 exterior walls are available as an option for buyers who prefer thicker wall framing.
