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.

Single-Family Residence Dwelling Planned Use District
The division of the city into zoning districts is based on the principle that similar conditions should prevail throughout a particular district. Some uses of land are appropriate neither as a permitted use, nor a special use, in certain districts and are, therefore, designated as planned uses or are otherwise subject to the planned use site plan approval process of this subchapter where such specified circumstances exist. It is the intent of this subchapter to authorize these planned uses only where the location and circumstances are appropriate to the use and a site plan is approved by the City Council. It is also the intent of this subchapter to increase the flexibility of development design through evaluation and approval of a site plan applying site-specific regulations. Approval of a planned use and corresponding site plan shall be considered a legislative act of rezoning. Any ordinance approving a site plan for a planned use shall be deemed to incorporate the provisions of this chapter. The term Planned Use shall mean the specified use, associated site plans and corresponding overlay district regulations authorized pursuant to this subchapter.
