Welcome to "The Koa Lanai House," a custom-designed architectural masterpiece by the late Patrick Killen, AIA--founder of Studio 9one2 and a pioneer of modernist beach design in Los Angeles. Set on a rare 3,524 sq ft corner lot just moments from the sand, this striking residence offers panoramic views from Malibu to Palos Verdes, including both Manhattan and Hermosa Beach piers--alongside exceptional indoor-outdoor living rarely found this close to the beach. Inside, the open-concept living space features approx 14-ft soaring ceilings, walls of glass, and newly refinished Brazilian cherry wood floors--each plank a unique work of art. A large terrace expands the living space, while the chef's kitchen centers around a 9.5-ft custom Acacia Koa wood island with built-in pop-up TV, Sub-Zero fridge, Viking 6-burner range, wine fridge, walk-in pantry, and breakfast bar seating for six. A second terrace off the dining area offers views of Catalina and Palos Verdes. The main level also includes a powder room, recessed lighting, and integrated in-ceiling speakers. Upstairs, all three bedrooms feature ensuite baths, ocean views, and smart audio integration. The primary suite includes a custom-built-in platform bed, daybed nook, private ocean-view terrace, dual vanity bath with rainfall shower, ceiling-fill Acacia Koa soaking tub, and walk-in closet. The lower level houses an expansive flex space currently configured as a combined screening room and fitness area, with polished concrete floors, a 135" projection screen, wet bar, and decorative fireplace--plus a guest suite with full bath access and sliding doors to the patio. Additional highlights include a wine cellar, laundry room, and a rare Sand Section yard with wraparound seating, grass lawn, water feature, and sunset-view pebble patio. The home includes a recently replaced roof, A/C, dual tankless water heaters, Nuvo filtration system, Tesla charger, and a 3-car garage with deep-bay storage and built-in shelving. Tech upgrades include Savant smart controls and rooftop deck potential (buyer to verify feasibility). Ideally located near both piers, the Strand, top-rated Mira Costa High, and local favorites like Martha's and The Bottle Inn--2114 Manhattan Avenue "The Koa Lanai House" is a modern coastal sanctuary with iconic views and timeless appeal.
