He was unable to finish this last project due to declining health, but his son Donnan managed to complete it. In 1937, Jeffers began work on an east wing that he intended to serve as a home for his boys, who were both in their 20s by then. After ceasing his stonework for a year or two, he then began work on a dining hall that would be completed in 1930. He completed these in 1920, and then began to work on a tower that would take him four years to complete. Soon after the cottage was complete, Jeffers himself would begin building a detached garage and a low, enclosing wall for a courtyard.

Originally, the house had one bedroom, a kitchen, a living room, a bathroom, and an attic. Murphy's stonemason began work on the house immediately, and with Jeffers signing on later as an apprentice, was able to complete the project by mid-August. Robinson Jeffers and his wife Una bought land at Carmel Point in Spring 1919, and in mid-May, contracted Mike Murphy, an established Carmel developer, to build them a stone cottage at Carmel Point.
