The Decatur Annex building was on NE 77th Street at the corner of 43rd Ave NE, at the southern end of what is now Decatur School. The little white wood-frame Annex was the last building from the complex of Navy housing, called Shearwater, which was on the site from 1945 to 1966.

The Decatur Annex building was located on NE 77th Street at the corner of 43rd Ave NE. It was demolished in July 2019.
In 2018 neighborhood activists learned that the school district planned to tear down the Decatur Annex, and the activists brought the matter to the City of Seattle Landmarks Board to advocate for historic preservation. The Annex building represented the era of World War Two housing for personnel of the Naval Air Station in Seattle and a time when housing for Navy personnel was racially integrated.
At the City of Seattle Landmarks Board meeting on January 2, 2019, the Decatur Annex failed to get enough votes in favor of historic preservation. The large cedar tree on the corner of the lot was preserved when the Decatur Annex was torn down during the week of July 8, 2019.
