Welcome to South Campus Estates — a coveted enclave of newer-construction homes in Federal Way. Built in 2023 by JK Monarch, this 5-bed, 3.25-bath Modern Farmhouse Craftsman offers 3,350 sq ft on a sprawling 15,118 sq ft lot, no HOA. The great room boasts soaring 18-foot ceilings, while the chef-inspired kitchen anchors the home with a 15-foot island, custom cabinetry to the ceiling, Quartz counters, and an oversized walk-in pantry. Engineered hardwood floors and generous hallways flow throughout. Upstairs, the spacious primary suite offers two closets and an en suite bath. A second en suite bedroom with its own ¾ bath joins two more bedrooms sharing a full bath, plus a bonus loft. A main-floor bedroom with a ¾ bath nearby offers flexible guest or office space. The seller commissioned substantial post-purchase upgrades, completed by the builder — including a 4th garage bay (housing a second kitchen with ADU potential), a backyard storage shed on a concrete slab, and the upstairs ¾ bath/second en suite conversion — a true investment beyond the recorded sale price. Enjoy 4 driveway spaces plus 4 in the garage. A large covered patio with TIG cover overlooks an expansive, level backyard — a blank canvas for landscaping, a pool, or a future DADU. Catch a partial Cascade Mountain view from the front of the home. Minutes to I-5, Costco, and West Hylebos Wetlands Park, with easy access to Seattle, Tacoma, SeaTac, and Puget Sound waterfront.
