Genton Property Group(GPG) on October 28 broke ground on the ultra-luxuriousFour Seasons Residences Los Angeles. Designed by the Los Angeles office ofCallisonRTKL, the condo project will boast a $50-million penthouse - the most expensive suite in Los Angeles, say project officials.

"This will be an iconic building that resonates back to Los Angeles and the LA School of Architecture, translated to a vertical platform," said GPG chief executive officer Jonathan Genton at the ground breaking ceremony.

Featuring 58 custom-designed luxury condominiums and townhouses and the 12,000-sq-ft penthouse, the 12-story property is located in the upscale North Robertson district, home to some of L.A.’s most stylish boutiques, galleries and restaurants. It sits in a residential neighborhood, across the street from the Four Seasons Hotel Los Angeles at Beverly Hills.

The project will offer interior designs by Martyn Lawrence Bullard and each private residence will include an open-concept indoor-outdoor living space to maximize natural lighting and yield dramatic views of Beverly Hills and the Hollywood Hills. Averaging more than 2,400 sq-ft, the homes will feature a clean and modern “Mid-Century” design aesthetic that is a signature of Los Angeles’s architectural heritage.

Callisonrtkl副总裁副总裁凯利·法雷尔（Kelly Farrell）告诉我，设计挑战的一部分是使建筑物在该地区融合。法雷尔说：“建筑物和许多不同的建筑语言有很多不同的高度，我们想创建一栋不仅可以独立存在，而且与邻里有关的建筑物。”

She said the new Four Seasons Residences is not the tallest or the smallest building in town, so "from an urban design point of view, we had a key role to play in connecting the pieces."

And then there is the signature penthouse, which was recently featured in Wall Street Journal and Vanity Fair. Occupying the entire top floor, the rooftop oasis will feature a private, 9,000-sq-ft rooftop garden oasis and pool enveloped by a 360-degree panoramic view of the city. Also included will be direct elevator access and a private six-car garage. The penthouse will sit above 58 luxury condominiums and townhouses across three wings – The Tower, Wetherly Wing and Almont Wing.

Genton says the project is already near 50 percent sold and is scheduled to complete in late 2017.
