Coding school and co-working space operator Galvanize Inc. has confirmed plans to open offices next year in a new tower being built in downtown Austin.

The Denver-based company, which operates as a combination coding school and co-working space, is scheduled to start finishing out its space in October in an office building across the street from the skyscraper that Google Inc. (Nasdaq: GOOG) is moving into at the site of the old Green Water Treatment Plant on the north shore of Lady Bird Lake at West Cesar Chavez and San Antonio Streets.

Galvanize plans to occupy three floors — 25,000 square feet — of the building and employ 25-30 workers, Mandes said.
