The 1 Hotel & Homes South Beach boasts an impressive 29 posh penthouses.

But its crown jewel — the $20 million, 3,955-square-foot duplex topper (the development’s largest and priciest) — remains the most drool-worthy, informed by the 1 Hotel brand’s embrace of luxe eco-conscious living and health-focused comforts.

Along with ocean panoramas, floor-to-ceiling windows, a gourmet kitchen and double balconies, the airy spread offers “eco-glam” perks, like organic dry cleaning, housekeeping and grocery-shopping services, and living-art installations (not to mention a Tesla house car reserved for residents making quick trips).

Miami-based interiors firm Rose Ink Workshop dressed the pad (which co-starred with Venus Williams on a recent Alexa cover) in sophisticated beachy furniture that subtly frames the stunning views.

The penthouse’s new owners will also get breezy access to other on-site wellness amenities: sunrise rooftop yoga, a SoulCycle, the first Bamford Haybarn Spa location in the country, a massive Spartan Gym and four restaurants, including the just-opened Habitat by chef José Mendín and a vegan eatery. The greatest luxury of a home? Never having to leave it.
