This planned $400 million apartment and retail complex at 5411 Wilshire Blvd. in the historical Miracle Mile district of Los Angeles, led by Walter N. Marks Inc. (developer) and Keating Architecture. But to stand out today, this tower will sport comforts that more than hearken back to the boulevard’s glory days. The 5411 Wilshire high-rise will also have several amenities, including an outdoor deck on the fifth floor big enough for a park with trees, flowers and a perimeter walking trail overlooking the city. There will be a dog exercise area, barbecues and two swimming pools, with attractions clearly targeted to millennial tastes. In addition to a gym, the building will have a two-lane bowling alley, a virtual reality gaming room, a golf simulator, dog-grooming space, demonstration kitchen, wine-tasting counter, billiard room and yoga studio. On the 42nd story will be a private rooftop garden and lounge. Tenants will step out of their cars and leave them to a robotic system that will park them underground and charge them if they are electric vehicles. Marks and Keating envision the tower, set to open in 2023, as an updated version of graceful prewar luxury housing on Wilshire Boulevard.
