Possibly the most historically significant period for the Chinsegut Hill manor house occurred during the stewardship of Elizabeth, Raymond and Margaret Robins. Elizabeth purchased the home for herself and her youngest brother Raymond. But following the purchase and before they had moved in, Raymond met and married Margaret Dreier. Upon their acquisition of the property in 1904, Raymond and Elizabeth renamed the property Chinsegut Hill and set out to improve the grounds. Over the years, Raymond and Margaret added a kitchen to the east wing of the house, a widow's walk and ventilator, the west chimney, an expanded study, and a music room. The Robins later added four bathrooms (1911), acquired additional land (1917]), added the porte-cochere (1925), and added a fifth bathroom, electricity, and a well (1933).
