Eustatia (Greek for "good place to stay") is a brick house overlooking the Hudson River in Beacon, New York, United States.

Located on Monell Place in the northwestern corner of the city, it is a rare survival in Beacon of a cottage in the High Victorian Gothic style.

[2] This cream-colored brick he also called for in the construction of his Arcade Building (1871) for Riverside, Illinois, a suburb under development by his once partner Calvert Vaux and Frederick Law Olmsted.

[2] It retains the form and reserve of many of Downing's designs, but adds the "polychromatic enrichment" of the Ruskinian Gothic style Withers had explored in Beacon beginning in 1859 with its Reformed Church.

[1] A garden next to the house planned by Henry Winthrop Sargent has been destroyed, but the interior retains many period details such as a tiled marble entry floor and dark walnut moldings after a fire.
