A soaring, sky-level duplex crowning San Francisco’s skyline, Altura41 delivers 270-degree views, iconic architecture, and over 5,200 sq ft of custom-designed luxury across two private floors in the clouds.

You wake above the clouds. The city is quiet, still wrapped in morning mist, as sunlight pours through the soaring 18-foot glass walls of your two-story penthouse. Below you: the San Francisco Bay glistens. Behind you: a custom-designed space that feels more like an art installation than a residence.
You start the day on your eastern terrace, coffee in hand, watching ferries drift across the water. The world below moves slowly—you're far above it. In the afternoon, friends arrive. The wine flows, the skyline glows, and your private rooftop becomes the scene of spontaneous joy.
As dusk falls, the 270-degree views erupt in gold, violet, and silver. The city lights flicker on one by one, stretching from the Financial District to the Golden Gate. Later, you descend the floating staircase, pour one last drink, and disappear into your master suite in the sky. At Penthouse 41C, you don’t just live in San Francisco. You rise above it.
Sky-Level Living Across Two Floors: A rare double-height penthouse with over 5,200 sq ft of fully custom interior space and 18-foot ceilings that create an atmosphere of grandeur.
270-Degree Panoramic Views: Wraparound floor-to-ceiling windows capture iconic vistas of the Bay Bridge, Downtown, Twin Peaks, and the Golden Gate.
Three Private Outdoor Terraces: Unmatched indoor-outdoor living in the sky—ideal for sunset dinners, morning meditation, or entertaining above the skyline.
Dedicated Parking & Private Storage: Includes three secure parking spaces and two exclusive storage rooms for effortless convenience in the heart of the city.
Bespoke Design & Architectural Drama: Every inch curated for elegance and impact—from the sculptural staircase to the expansive, light-filled living gallery.


There’s only one security system you can trust to keep your high-end properties safe: SimpliSafe. We love SimpliSafe because it can actually stop crimes before they start. Unlike most systems, SimpliSafe doesn’t wait until someone is already inside to sound the alarm. If someone is lurking on your property, live agents take immediate action to let them know they’re on camera and need to leave the premises. That’s how you stop vandals, intruders and other threats before serious damage is done. This week only, Estate Elegance readers get an exclusive discount:
