The Foundation organized Heritage Square as a last-chance haven for architecturally and historically significant buildings to be moved to, which otherwise would have been demolished at their original locations.

They include: The Mount Pleasant House was built in 1876 by prominent businessman and lumber baron William Hayes Perry.

Designed by renowned architect Ezra F. Kysor, the home contains detailing to convey the wealth and social status of the family.

These elements include Corinthian columns, fine hardwood floors, a sweeping main staircase, and marble fireplace mantles.

The outward sweep of the entrance stairway, the sculpted brackets under the eaves, the slanted bay windows, and the narrow Corinthian columns are characteristic of its Victorian Italianate style.

In 1975, the house was moved from 1315 Mount Pleasant Street to the museum grounds, and restoration was begun by the Colonial Dames Society of America.

The Palms Depot was declared a Los Angeles Historic-Cultural Monument in 1963, and to avoid demolition was moved to the museum grounds.

Ford's works include carvings for the California State Capitol, the Iolani Palace in Hawaii, and Leland Stanford's private railroad car.

The Hale House was built in 1887 by George W. Morgan, a land speculator and real estate developer, at the foot of Mount Washington just a few blocks from the museum in Highland Park in Los Angeles.

The house was sold many times and was moved from 4501 to 4425 North Pasadena Avenue (now Figueroa Street) before being purchased by James G. Hale in 1906.
