In 1979, the building was donated by John Rauch Jr. to the Junior League of Indianapolis to be used for their headquarters and operated as an event venue and house museum.

After Matilda's death in 1923, their daughter Gertrude and her husband John G. Rauch, a lawyer who became president of the Art Association of Indianapolis, joined Gustav in the home.

The house was originally decorated with oriental rugs from Persia, moire silk wallpaper, several ornate mantles, stained glass windows, heavy velvet curtains, hand-carved woodwork, inlaid hardwood floors, and marble bathrooms—much of which survives to the present.

The house is architecturally distinctive for its castle keep-inspired tower, thick brick walls, red tile roof, and large stone porch entrance.
