Welcome to ''Bluff House,'' a mid-century modern, Prairie House masterpiece built in 1955 by architect Larry Pleasant & master builder John Skotch. Perched in Grandview like a luxury treehouse, this meticulously maintained, 4-owner home offers 2,055 sq ft of total living space blending natural materials with premium modern updates (1998/2012 additions). The main level features original white oak floors, a wood-burning fireplace, and premium Weathershield wood casement windows. A chef's kitchen boasts flat-panel cherry cabinets, quartz counters, hand-cut tile backsplash, seagrass limestone floors, and high-end Dacor appliances. Relax in the 2012 Garden Room addition beneath a trayed ceiling and a unique 7'2'' x 3'3'' double-pane commercial light well. French doors lead to a serene blue stone patio featuring a fountain, landscape lighting, and a custom cedar fence. Retreat to the spacious primary suite (14'3'' x 14') with 2 generous closets and an en-suite bath featuring double sinks with kickplate foot heating, a walk-in shower, a water closet, and a heated Jacuzzi tub. A lovely guest room with beautiful hardwood floors sits across from a full hall bath flanked by 2 deep linen closets. The finished walk-out lower level includes a family room with a gas fireplace, private office, heated/cooled workshop/gym, and an epoxy-floor laundry. Set on a beautifully landscaped .22-acre oasis, the grounds boast mature trees quarterly inspected by Ahlum & Arbor, an irrigation system, and abundant storage throughout. Truly incredible design!
