The estate contains seven buildings, the most notable being Elstowe Manor and Chelten House, which are historic mansions designed by Horace Trumbauer.

The unique interior features, such as the ornately carved wood and gilded molding, marble columns and accents, frescoed ceilings, gargoyles and the like, were crafted in Europe and shipped to the United States, where they were assembled on site.

Along with the mansion, Trumbauer also designed the wrought-iron gates at the entrance to the estate, as well as a small gatehouse, a powerhouse, and an eight-car garage.

The dedication of the Sisters to preservation of the historic mansions on the estate was extraordinary and, as of 2013, the original features and architectural details remain intact.

It was described as the most significant example of Gilded Age architecture in the region by John Gallery of the Philadelphia Preservation Alliance.

Over time, the needs of people coming on retreat changed, and the economic challenges of operating the buildings became unsustainable for the Dominican Sisters.

In February 2009, the Dominican Sisters sold the 42-acre property to the Land Conservancy of Elkins Park, PA, who intended to use the facility for group spiritual, health and wellness education retreats, and also as a venue for elegant special events.

The property was reopened in September 2009 as Elkins Estate and has hosted a number of wedding receptions and events.
