This house plan can be modified to fit your family’s lifestyle and your lot’s specifics.
Plan 40884R is a 3-bedroom single-story house plan with French Country elegance, offering 5709 ft² under a hip and valley roof accented by gables and dormers, with exterior walls of natural stone and siding. English, European and traditional American influences shape this luxury mansion, a single-family home with a stately street presence. The ridge runs parallel to the street at an 8/12 pitch, and the house measures 110'0" wide and 32'0" deep, rising 41'6" high. The exterior walls are framed with 2x6 wood, and 2x4 framing is also available on request.
The heart of the house is an open floor plan built around a large family room with a fireplace and vaulted ceilings. Large windows and floor-to-ceiling windows bring daylight deep into the rooms and frame the views from every seat. The large kitchen is made for both daily routines and big gatherings: a central island, a breakfast bar for quick meals, a sunny breakfast nook and a walk-in pantry for serious storage. A second kitchen adds flexibility, whether for entertaining on a grand scale or giving extended family their own space. A media room and a home office round out the living areas, so movie nights and focused work each have a place of their own.
This house plan with two master suites places the primary master on the main floor, with walk-in closets that keep the bedrooms calm and uncluttered. An in-law suite gives visiting parents or older children comfortable privacy. Four full bathrooms and three half baths mean no one waits in the morning. Practical rooms are generous: laundry on the main floor, a mudroom off the entry, a utility room and ample storage. An exercise room, a bonus/flex room and a workshop let the home adapt to hobbies and changing needs, and an elevator connects the levels with ease.
The house stands on a walkout basement, and it is also available with a slab or a crawl space foundation. The 3-car drive-under garage has a side entry, keeping the front facade clean, and offers space upstairs. Guests arrive beneath a classic portico, while stacked porches, a screened porch, a balcony and a patio extend the living space outdoors, ready for long summer evenings and quiet morning coffee.
