Offering 8,350 square feet of living space on an expansive 9,000 SF lot, 622 24th Street stands among the largest and most architecturally significant homes in Santa Monica's coveted Gillette Regent Square, north of Montana Avenue. Designed by world-renowned architect Irving Tobocman, his only residential project in California, this striking Bauhaus contemporary residence represents a rare fusion of scale, architectural pedigree, and timeless materials seldom found in the neighborhood. Defined by full-slab Italian travertine floors, custom oak millwork, and expansive walls of glass, the home reflects Tobocman's disciplined approach to proportion, natural light, and spatial clarity. A newly renovated 2026 kitchen anchors the residence, appointed with dual Sub-Zero refrigerators, Gaggenau ovens, oversized island, breakfast area, desk, and walk-in pantry, all framed by a distinctive semi-circular window overlooking the backyard oasis. The main level unfolds through dramatic entertaining spaces, including a formal living room and dining area that flow into an expansive family room featuring a travertine bar, built-in Sonos system, and floor-to-ceiling sliding glass walls opening to the private grounds and pool, creating seamless indoor-outdoor living. Outside, the property offers a rare level of privacy for homes north of Montana Avenue, enhanced by mature landscaping, a newly constructed front privacy wall and hedge, and a resort-like backyard with brand-new saltwater pool, spa, and baja. Upstairs, a dramatic double-height corridor with architectural glass block leads to four spacious en-suite bedrooms with oversized walk-in closets, arranged around a sunken lounge. The primary suite serves as a private retreat featuring dual bathrooms, a jacuzzi soaking tub, an expansive walk-in closet, and a 35-foot private terrace overlooking the pool and garden. The lower level introduces an impressive 30' x 47' recreation room, offering exceptional flexibility for entertaining, recreation, or wellness use. This level also includes a newly renovated 2026 laundry room, second office, 371 SF storage room, and a private guest suite with its own living room and full bath. Located moments from Brentwood Country Mart, Brentwood Country Club, Franklin Elementary, and the boutiques and cafs of Montana Avenue, 622 24th Street represents a rare opportunity to own a one-of-a-kind architectural residence of scale and sophistication in Santa Monica's most sought-after neighborhood.
