In the wing to the right of the main block of the house was a sunroom and to the left was the service wing that included the kitchen and servants quarters. On the second floor was the Phillip's private quarters containing four family bedrooms, each with a bathroom, dressing room and sleeping porch, and two guest rooms. A staircase located between the receiving hall and dining room accessed the lower floor leading to the Southwestern rooms and to the porte-cochère. In 1938, the Phillips donated Villa Philbrook and its surrounding gardens to the city of Tulsa, in hopes that the estate would be used for art and cultural purposes. While the principal rooms on the first floor were left virtually untouched, the rest of the space has been remodeled for its use as a public institution.
