The Danvers house is the residence of the Danvers family. It is located in Midvale.
Superman introduced Kara Zor-El to Jeremiah, Eliza and Alex Danvers at the Danvers house when she arrived on Earth.
Kara and Alex eventually moved out of the house to attend college in National City.
In early 2016, Alex and J'onn J'onzz, who were on the run, stopped by the house briefly for supplies. Eliza revealed to them the Myriad situation in National City.
In late 2017, Kara and Alex returned to Midvale and stayed at the Danvers House for a few days to take some needed time off after Alex broke up with her fiancée, Maggie Sawyer.
