The Clement House, also known as the Red Cross Building, is a 17,000 square feet (1,600 m2) mansion in Buffalo, New York, that was built in 1913.

The entire left side of the house was the Clement's 1,040 square feet (97 m2) music room which had two Steinway grand pianos, a harp and a pipe organ.

Carolyn's father had originally sold a portion of his property to William H. Gratwick who had Henry Hobson Richardson design the house in 1886 as his last commission.

[10] In 1979, an office building and an adjoining structure connected by an atrium were built on the back portion of the 4 acres (1.6 ha) plot near the carriage house and another parking lot.

In 2018, BestSelf Behavioral Health, a non-profit agency, paid $3.15 million to buy the 53,500 square feet (4,970 m2) complex on 2.85 acres (1.15 ha) behind the Clement Mansion.
