Viewed from the street, you might not give this somber, square-edged, 1950s-style two-story a second glance, thanks to its battleship-gray paint, black-framed windows and flat-topped roof littered with ugly A/C units. Even the driveway seems designed to avert attention, with its prison-like black metal security gates leading to a sea of concrete with not a flower bed in sight. As far as curb-appeal goes, the place is decidedly lacking. Yet if this modernist home in Los Angeles’ tony Hancock Park neighborhood sells for anywhere close to its $24.99 million asking, it would hit the record books as the area’s priciest pad. Why so expensive? Open that solid wood front door in the bunker-like entryway, step inside and your jaw will descend at the instant transformation from somber to stunning. “This is nothing less than a triumph of architecture and design. It really is unlike anything Hancock Park has ever seen before; the beauty and caliber of the work is second to none,” says listing agent Aaron Kirman, of the Aaron Kirman Group at Compass, who shares the listing with Compass colleague Verna Helbling and Adam Rosenfeld with The Agency. He’s not wrong. The first thing you see entering the foyer of this sprawling, 13,000-square-foot, seven-bedroom compound is a seemingly gravity-defying glass-and-white-marble floating staircase. Alongside it hangs a complex Italian Malerba pendant chandelier made up of a multitude of polished nickel tubes. On the floor, quirky, chevron-style marble inlays point your eye past the sexy, Miami South Beach-esque bar and the Italian kitchen with its acres of posh granite, all the way to the home’s backyard paradise. It’s all the work of Meir Siboni and Jonathan Menlo, of celebrity property developers Elite IMG. They bought the near-dilapidated 1950s-built home on Hancock Park’s South Hudson Avenue back in 2016 for $5.3 million. While strict Hancock Park preservation regulations prevented the home from being leveled, Siboni and Menlo kept the basic footprint along with the outer walls, then took the structure down to the studs and rebuilt everything. “It took two years to learn what we could and couldn’t do, then another two-and-a-half-years to re-imagine the home with a single-minded focus on quality and design,” Siboni tells Robb Report. At an early stage, he and Menlo brought in Irene Acosta-Hershman of LA-based IA-Design Studio, together with Michael Palumbo of Palumbo Design, to move walls, add spaces, pick finishes and create a new flow to the six-bedroom main house. And, in night-and-day contrast to the somber look of the front of the house, the rear is all inviting, soft-gray brick surfaces, with massive glass pocket doors that open the interior to the outside. It’s the same on the second floor, with a full-width terrace, huge windows and a glass balustrade. Exquisite interior features include the oversize kitchen made-up of super-high-quality Italian Scavolini cabinets, glossy lacquered-wood walls and twin islands. And for those times the catering staff are called in, there’s a full, professional-grade kitchen tucked away.
