About this home

Multigenerational space, versatility, and room for all your toys in the desirable Thunderbird area! Situated on a fully fenced .44-acre lot, this updated spacious split-level home offers room to spread out, entertain, & enjoy flexible living arrangements. Vaulted ceilings w/exposed wood beams and a cozy gas fireplace welcome you into the main living area. The generous dining room features custom cabinetry & flows seamlessly into a beautifully remodeled baker's kitchen, thoughtfully designed for those who love to cook! Highlights include Corian countertops, a full tile backsplash, pull-out drawers, custom spice racks, and clever storage solutions. Just off the dining area, a partially covered composite deck provides the perfect setting for year-round entertaining. Three main-level bedrooms include a spacious primary suite with its own private deck overlooking the fully fenced backyard & a five-piece bath featuring a sunken tub. The light-filled lower level offers exceptional multigenerational living potential, complete with a family room, second gas fireplace, kitchen area, bedroom, three-quarter bath, & separate exterior entrance. With the potential to create additional separation, this flexible space offers plenty of possibilities! An additional bedroom, utility room, and access to the two-car garage complete the lower level. Outside, enjoy a storage shed, EV charger, & parking for approximately six additional vehicles, w/plenty of room for RVs, boats, & recreational toys.
