Fifty at First is a proposed office tower at 50 First Street in San Francisco. The project's own site describes a hospitality-driven sensibility across the building and names three amenity parts: a private reception and arrival experience, a fifth-floor event space and terrace, and a fortieth-floor sky lounge. The site lists 915 feet, 56 floors, 1.5 million square feet of workplace and 15-foot-6 deck-to-deck heights.
The amenity suite the project publishes
The site names the three pieces in one sentence and calls the result a signature suite. It lists floor plates to 32,000 square feet and more than 20,000 square feet of outdoor space. The rest of the pitch covers engineering: an all-electric building with net-zero operational carbon, a seismic claim, and an art programme developed with guidance from SFMOMA. JLL holds the exclusive office leasing assignment, with Christopher T. Roeder and Charlie Hanafin named as contacts.
A private reception and arrival sequence
The arrival piece leads the list. The lobby is an open box with a four-story ceiling and full-height windows. The application adds a corner cafe at First and Stevenson Street, landscaped planters and public open space at street level. The record names no concierge operator, no front-desk staffing model and no service standard for the arrival floor.
Event space and a terrace on the fifth floor
San Francisco YIMBY's report on the October 2026 application describes employee amenities centralised on the fifth and 40th floors, each with an indoor space connected to an outdoor terrace. A sky lobby on those levels moves people between elevator shafts. No published material carries a floor area, a seat count, a divisible meeting-room schedule or a service kitchen for either level.
The sky lounge above the fortieth-floor transfer
The fortieth floor holds the second amenity level on the same pattern. The site markets bridge-to-bridge views from the upper plates. Gensler is the project architect, Field Operations handles landscape architecture, Magnusson Klemencic Associates the structural engineering and MEYERS+ the mechanical, electrical and plumbing work. The tower would stand second in the city by height, behind the 1,070-foot Salesforce Tower.
The dates behind the programme
The San Francisco Recovery Fund bought the site after creditors took it from Oceanwide Holdings, which halted construction on the two-tower scheme in 2019 and 2020. The Real Deal reported the fund's hiring of BXP as development adviser on 31 July 2026, with a remit covering building design, systems, leasing strategy and market positioning. Renderings by Gensler appeared in September 2026. The formal application reached the city in October 2026, reported by YIMBY on 13 October. The project site states occupancy in 2030.
A second tower carrying 169 guest rooms
A second tower at 528 Mission Street would rise 54 floors and 605 feet, with about 636,100 square feet. The October application lists 255,350 square feet of hotel use, 156 market-rate apartments and 169 guest rooms, plus 2,000 square feet for a restaurant. Full build-out would include parking for 504 bicycles and 385 cars. The applicant states that the tower keeps its 2016 entitlements and that the footprint becomes publicly accessible open space before construction starts there. No date for that tower appears in the application.
No operator, no capacity, no booking route
No hotel operator, hotel brand, event sales contact, capacity figure or booking channel appears for the amenity levels. No food and beverage operator is named for the fifth floor, and SFist reports the building's food and beverage offerings as undetermined.
What a hotel seller can take from an office programme
The building sells arrival, a lounge and a meeting floor to tenants. The published order runs reception first, event space second, sky lounge third. That order sets the moments a tenant will judge: the arrival, the gathering floor, the view.
Hotels chasing the same corporate account can read the tenant brief out of that sequence. They can price the arrival service, the private dining room and the rooftop against a building that opens in 2030.
