- For Honor Harrington's Grayson residence, see Harrington House.
It would normally have been called "Harrington House", but as that name was already used for Harrington's residence in Harrington Steading on the planet Grayson, it was named the "Bay House" instead, due to its location on Jason Bay's eastern shore, a ten minute aircar ride from the center of downtown Landing.

The house also served as the Harrington Steading Embassy on Manticore, and was the location where treecats demonstrated the ability to use sign language in public for the first time, in a private showing to Queen Elizabeth III and her treecat Ariel. (HH9)
