[1][3][4][5] Lanterman, who had treated victims of the 1906 San Francisco earthquake and fire, insisted that the foundation, floors and walls of his house be built from reinforced concrete, and Haley interpreted the aesthetics of Craftsman-style wood-built bungalows in the new material.

The house retains much of its original furniture and finishes, including a grand ballroom that occupies the entire second floor,[1][3][6] and Dr. Lanterman's consulting rooms in the basement.

It is home to the Lanterman House Archives, which contains family materials as well as documents and photographs from the defunct La Cañada Flintridge Historical Society.

[3][7] The Lanterman House is open for tours most Tuesday and Thursday afternoons from 1 p.m. - 4 p.m. and the first and third Sundays of each month from 1 p.m. - 4 p.m.

The Lanterman House History Center and Archive is available for public research by appointment.
