The oceanfront home where Dr. Seuss wrote 'The Cat in the Hat' is on the market for $9.95 million. Take a look inside.

• The Geisel Estate, the former home of children's author Theodor Seuss Geisel, is up for sale.
• The oceanfront four-bedroom four-bathroom home in La Jolla, California, spans 5,004 square feet.
• Geisel wrote 42 books there, including "The Cat in the Hat" and "Green Eggs and Ham."

Even the Grinch would have to agree that this $9.95 million home overlooking the Pacific Ocean is pretty nice.

Beloved children's author and illustrator Theodor Seuss Geisel, who created iconic characters such as The Cat in the Hat, the Grinch, and the Lorax under the name Dr. Seuss, lived and worked at his La Jolla, California, estate for over four decades.

The Geisel Estate, as it has come to be known, is now on the market. The historic property, listed by Jason Barry Team, still features the office and study where Geisel wrote and illustrated 42 of his more than 60 books.

"This property and view was much of what inspired some of Dr. Seuss's most-read children's books," real estate agent Jason Barry told Business Insider. "It is an honor and a privilege to represent this one-of-a-kind estate."

The Geisel Estate is located on a hillside in La Jolla, a neighborhood in San Diego, California.

In 1948, Theodor Seuss Geisel and his wife, Helen Palmer, commissioned Thomas L. Shepherd to design the home around the property's existing Spanish Revival observation tower.

After it was completed in 1950, Geisel lived there until his death in 1991. It was then donated to the University of California, San Diego.

The 5,004-square-foot home is situated on 1.51 acres of oceanfront property.

The four-bedroom, four-bathroom home has been renovated since Geisel lived there.

The floor-to-ceiling windows provide sun-soaked views of the Pacific coast.

It also comes with a pool and a pool house.

The crown jewel of the home is Geisel's office, designated a protected landmark by the City of San Diego's Historical Resources Board.

Here, Geisel wrote 42 books as Dr. Seuss, including "The Cat in the Hat," "The Lorax," and "Green Eggs and Ham."

The Geisel Estate is listed by Jason Barry Team, a San Diego-based real estate agency, for $9.95 million.

"This is more than a house — it's a legacy of creativity," Jason Barry said.
