Plan description

Juggling family life and maintaining a sense of order can be challenging, the Onyx’s spacious front porch and utility room with a mud area provide a practical solution for managing daily routines. The open-concept layout seamlessly connects the family room and dining area, creating a central hub for gatherings and everyday living. The kitchen, equipped with ample granite counterspace, a ceramic tile backsplash, and industry-leading appliances, simplifies meal preparation and cleanup. A large walk-in closet in the master suite offers generous storage, while energy-efficient features contribute to lower utility bills. With three bedrooms and two bathrooms spread across 1607 square feet, this single-story home provides comfortable living space for a growing family. The two-car garage adds convenience, and optional upgrades like a covered patio and dual vanities in the master bath allow for personalization.
