The SF Examiner has a rendering of the 40,000-square-foot addition to the War Memorial building, along with a story about the proposal.
Looks like what we have above is the latter of two designs being considered for the annex, "neither of which have been vetted by the historic preservation community" at this point.
The architect isn't mentioned, but presumably it's Mark Cavagnero — in his SFBT profile this past Friday, he mentions a Beaux Arts option for the addition that would blend right in with the existing building, and another option that would be "very deferential in massing, shape, form and size, but ... a more contemporary building utilizing green technologies."
The $60 million addition would allow San Francisco Opera to consolidate a number of operations currently spread throughout the City, and has already been thumbs-up'd by the War Memorial's board of trustees, though "the hurdles it would take to get this done are mammoth."
