50 First Street Tower One

While the designs for a cluster of Renzo Piano-designed ultra-thin towers at the corner of First and Mission may have fallen by the wayside, plans for building upon the seven parcels a.k.a. 50 First have not as Marcus Heights, LLC, proposes to demolish four existing structures and develop three SOM designed towers ranging in height from 184 to 915 feet with solar/wind energy collection features atop.

The project site, comprising seven parcels, and portions of Elim Alley and Jessie Street, is approximately 56,860 square feet in size. All lots are within Block 3708 and include 50 First Street, 62 First Street, 76‐78 First Street, 88 First Street, 512 Mission Street, 516 Mission Street, and 526 Mission Street; the three parcels with addresses on Mission Street are currently vacant.

The three proposed towers would accommodate a mix of office (approximately 1.25 million square feet), residential (about 182 dwelling units), retail (approximately 43,000 square feet), and hotel (about 266 rooms) use, along with a 15,000‐square‐foot entertainment venue (performance theater), five levels of below grade parking (about 310 spaces), off‐street loading spaces, and publicly accessible open space.

50 First Site Plan

Tower One would front on First Street and would span the portion of Jessie Street that runs through the project site. The 64‐story building would be 850 feet tall to the roof (915 feet tall to the top of the parapet and solar/wind energy collection features), and would include an 83‐foot tall base that would also have frontage on Stevenson Street, where the proposed performance theater would be located. The building would contain approximately 43,000 square feet of retail and the 15,000 sf performance theater on levels one through three. Mechanical space would occupy the topmost story. The remaining 60 stories would provide approximately 1.25 million square feet of office space. The tower would span the easternmost portion of Jessie Street, which would be closed to vehicular traffic and converted into a 20‐foot‐tall public pedestrian passageway (Jessie Street Galleria) flanked by retail space and lobbies serving the office use. The First Street frontage, moving from north to south, would include the theater entrance, office lobby, entrance to the Jessie Street Galleria, second office lobby and a retail store. The Stevenson Street frontage would include retail space and a garage/loading dock driveway separated by an open pedestrian entry to the interior passageway linking Stevenson Street, Mission Street and First Street via the proposed Jessie Street Galleria. An approximately 5,100‐square‐foot publicly accessible roof terrace would be developed atop the 83‐foot tall theater, fronting on Stevenson Street.

Tower Two would front Mission Street and Ecker Place. The 56-story building (605 feet to the roof, 640 feet to the top of the parapet) would include residential and hotel uses above the ground-floor entrances and two levels of hotel service space. Approximately 266 hotel rooms would be located on floors four through 22 and approximately 160 residential units would occupy levels 23 through 55. A mechanical level would occupy floor 56. The ground floor would include a hotel entrance, a residential lobby on Ecker Place, and a retail space at the corner of Mission and Ecker. The hotel lobby would be on the second floor, and hotel function space would occupy level 3. Publicly accessible open space would occupy the set back area between Tower Two and the Mission Street and Ecker Place property lines.

50 First Tower Two

Tower Three would be located at the northwest corner of Mission and First Streets. This 15-story, 174-foot tall building (184 feet tall to the top of the parapet), would include retail space and a residential lobby on the ground floor and 22 residential units on the upper levels. Tower Three would be separated from the rest of the proposed project by a “T” shaped parcel (84 First Street) that is not under the control of the project sponsor and not included in the project site.

The project as proposed would either require approval of the proposed Transit Center District Plan and accompanying rezoning with respect to increased height limits or a site-specific amendment of the Planning Code and General Plan height maps by way of the Board of Supervisors upon recommendation from the Planning Commission.

Next step, the preparation of an Environmental Impact Report (EIR).

  1. Beautiful. I’m excited to see some more detailed renderings and am glad SOM still has a shot in the neighborhood after losing the Transbay Tower competition. Come on economy!

  2. 180 residential units…only? Hardly enough votes to swing a dead dog election in District 6. Daly is much smarter than I thought.

  3. I’m with R. I thought the only permitted new construction in the FiDi was sheer glass curtain walls to the lot line, with rectilinear lines.
    Looks good so far.

  4. Interesting.. Fantasy.
    I can’t get by that the site contains three separate parcels (510 Mission, 40 & 84 First) “not under the control of the project sponsor and not included in the project”..
    600+ & 900+ ft tall towers ?
    There’s gotta be a screwball back story.
    And don’t even get me started on the windmills, panels, propellers and what not….

  5. Organic rectangle. I’m liking. Similar shape as Pelli’s Transbay tower, v similar to the recently approved Pelli near Empire State Building. No? Appears a trend and a good one given the boxiness of Main/Fremont St (San Fran) and 6th Ave NYC. Not comparing other than rigidity of the existing visual experience in both places.

  6. I think we all need to start using the word “undulate” more when talking about possible future SF skylines.
