The Roseberry Homestead, also known as the Walter Gess House, is a classic Georgian house, erected of rough-cut quarry stone between 1765 and 1783 located at 540 Warren Street in the town of Phillipsburg in Warren County, New Jersey, United States.

It was added to the National Register of Historic Places on April 3, 1973, for its significance in architecture and exploration/settlement.

There is a large cooking fireplace in the kitchen, with a removed brick oven.

A porch extended across the entire front, permitting access to the higher level first floor, but that has long since disappeared.

[3] The Roseberry Homestead has fallen into considerable disrepair, and has been boarded up for at least 15 years.
