Plan description

With the demands of a busy family, the Plan 1242’s expansive study offers a quiet retreat after a long day, providing a dedicated space for focused work or simply unwinding. This home, starting at $224,995, can be configured with three bedrooms and two bathrooms, ensuring plenty of room for everyone to spread out and find their own space. The open concept floorplan seamlessly connects the kitchen – complete with a convenient breakfast bar and stainless steel appliances – to the living room, creating a natural hub for family gatherings. An oversized 2-car garage, equipped with an electric car charger, provides ample storage and convenience, while the covered patio offers an inviting spot for outdoor entertaining. Just moments from Jarrell ISD and the new Igo Elementary School, and with easy access to Round Rock Premium Outlets® and Wolf Ranch Town Center, life is effortlessly connected. The home’s sprinkler system and energy-efficient windows contribute to a comfortable and sustainable lifestyle, and the optional multi-gen suite allows for the flexibility to accommodate family members as needed. Enjoy the convenience of a utility/laundry room and a bathtub in the primary bedroom, all within a beautifully sodded yard.
