OAKLAND — A big office tower is being planned in downtown Oakland, a spire that would rise in the city’s bustling Uptown district, developers said Thursday.

The 875,000-square-foot office building — large enough to accommodate potentially 3,500 to 4,400 workers — would be built near the corner of Telegraph Avenue and West Grand Avenue, according to project developer TMG Partners.

“Telegraph Tower leads the next generation of office buildings for Oakland with its emphasis on expansive, open floor plates, some of the highest ceilings of any Bay Area office building, and a large proportion of outdoor space,” said Michael Covarrubias, TMG Partners chief executive officer.

These are the sort of amenities that developers believe would cater to tech workers, whose employers hunger for attractive offices that they can use to recruit and retain skilled employees.

“We took every lesson we have learned about what companies want today and designed Telegraph Tower as a workplace environment that is entirely focused on delivering the ‘right’ employee experience,” Covarrubias said.

Among the major tech companies already committed to the Uptown area: Square, a financial services tech giant, previously revealed it had leased all of the office space in Uptown Station, a mixed-use office and retail complex built on the site of an old Sears department store.

The 28-story tower will include a community theater, street-level retail, a cafe, an art space, a big wellness center, outdoor terraces, fire pits, and rooftop amenities.

Construction of Telegraph Tower is expected to launch sometime in 2020. Commercial real estate firms JLL and Cushman & Wakefield are seeking tenants to lease the office high rise.

“Telegraph Tower is a stunning workplace that offers the Bay Area’s best commute to the companies lucky enough to call Oakland home,” Oakland Mayor Libby Schaaf said.
