143 Marguerita Ave presents an exceptional opportunity on one of Santa Monica's most desirable streets, just four properties from Ocean Avenue, on an expansive, tennis-court-sized 14,626 sq ft lot along a wide, palm-tree-lined street. This beautifully appointed 6-bedroom, 8-bath ocean-view residence spans nearly 5,900 sq ft of elegant living space, designed for both grand entertaining and everyday comfort. Highlights include a dramatic entry with a sweeping staircase, over-scale light-filled formal living and dining rooms with soaring ceilings, and a thoughtfully designed floor plan with multiple en-suite bedrooms. The main level features a wood-paneled library or office and separate staff or guest quarters. The chef's kitchen, remodeled within the last six years, showcases marble countertops, custom cabinetry, and premium Sub-Zero and La Cornue appliances, opening to a bright breakfast area and spacious family room overlooking the grounds. Upstairs, the expansive primary suite offers a private retreat with ocean views and an oversized walk-in closet and dressing room area, complemented by three additional bedrooms. Some bathrooms offer the opportunity for a buyer to update and personalize them to their taste. The private resort-style backyard is a true sanctuary with mature landscaping, numerous fruit trees, and lush high hedging providing total privacy. It features a lap pool, hot tub, and a separate pool house with a sauna and shower, along with multiple areas for outdoor dining and lounging, including a pergola-covered patio. A detached guest house at the rear of the lot with its own entrance and garage adds flexibility and value, while the main house offers a 3-car subterranean garage with substantial storage. Additional features include hardwood flooring throughout most of the home, three fireplaces, central HVAC, central vacuum, and a well-maintained concrete shingle roof, all just moments from the beach, renowned restaurants, Palisades Park, premier shopping in the heart of Santa Monica, and the iconic Santa Monica Pier.
