Welcome to 3504 Castelaine Cir, a custom-built luxury estate on 1.43 private acres in Wake County — zoned for top-rated Apex schools, with no city taxes and no water/sewer bill. Designed and built by one of the Triangle's recognized Parade of Homes boutique builders, every room was thoughtfully planned by the owners themselves, resulting in a level of craftsmanship and personal detail rarely found in production construction and lives much larger than bedroom count. Thoughtfully designed across 3 finished levels with flexible living spaces throughout. The basement level offers a full second living space complete with a kitchen, bedroom, laundry, a private screened porch, and two separate entrances and a dedicated separation door — functioning independently from the rest of the home. The bathroom features a zero-threshold roll-in shower and 3/0 doors for accessible design. The main level features a chef's kitchen with an 8' island, custom barn door pantry, gas range, and a family room with a gas fireplace and screened porch with infrared heat for year-round use. The primary suite includes a spa-style bath with heated jetted tub, oversized super shower, and expansive walk-in closet. Set on 1.43 fenced acres with mature trees beyond the property line, this estate also includes a 3-car garage with RaceDeck flooring and 2 Tesla EV chargers (car lift avail. for purchase separately). Freshly painted, power washed, and pre-listing inspected adds buyer confidence and move-in ready condition. Assumable mortgage rate is 3.75% thru Truist Bank. Owner is Listing Agent.
