Property Description

If you're looking for a home with space to spread out, a backyard you'll actually use, and a floor plan that stands out from the crowd, this one is worth a look. Designed with both functionality and comfort in mind, this stately home offers a refreshing departure from the typical cookie-cutter layout. Multiple living spaces, flexible-use rooms, and thoughtful design create a home that easily adapts to today's lifestyle. The kitchen serves as the heart of the home, featuring granite countertops, stainless steel appliances, a gas cooktop, a beverage fridge, abundant prep space, and an inviting eat-in dining area. Just beyond, you'll find one of the home's standout features—a massive covered patio overlooking a lush, fully fenced backyard. Whether you're hosting, enjoying your morning coffee, or unwinding at the end of the day, this outdoor space was made to be enjoyed. Upstairs, you'll find four generously sized bedrooms, each with its own walk-in closet. The size of the primary bedroom and walk-in closet are noteworthy; you have more than enough room to create your own retreat. The primary en suite features a stand-up shower, a lovely garden tub and double sinks. Another bathroom and a spacious loft that offers endless possibilities as a media room, reading nook, home office, hobby space, or additional lounge area complete the upstairs. Need even more room? The full unfinished basement is already being enjoyed as a home gym and music room, while still offering substantial storage space. Whether you envision a home theater, recreation room, workshop, guest suite, or additional living area, the opportunity to customize and finish the space to fit your needs is already here. Additional highlights include main-floor laundry, a versatile bonus room currently used as an office that could easily serve as a fifth bedroom, and a brand-new roof in 2025. Beyond the home itself, residents enjoy access to exceptional neighborhood amenities including a community pool, park, and walking trails—providing opportunities to relax, stay active, and enjoy the outdoors just moments from your front door. With its unique layout, impressive living spaces, expansive backyard, and endless potential, this is the kind of home that offers more than square footage—it offers options.
