The address of this property is 1977 Carmen Avenue, between Vista Del Mar Avenue and Gower Street, north of Franklin.
The land was purchased in early 1910 by Joseph L. Giroux, whose career was in mining, especially copper:

"Everything in the place was copper, right down to the doorknobs and bathtub," recalled a later resident:

In the home's first few years, Giroux made some minor additions and changes, such as the addition in 1913 of a one-room
"summer house" with a dirt floor on the west side of the property, described on the building permit as "bamboo house covered
with shingle + grass over same / 4 bamboo post + bracing for support"
Giroux had some trouble with a maid in 1914:

Tragically, Giroux had more serious trouble with his eldest son, George. It is even more sad considering Giroux had to take
his ex-wife to
court to get physical custody of his son when he was a child:

Giroux was exonerated in the shooting of his son. George had come at his father with a loaded revolver. As the two
struggled over a second revolver, George was shot.
His son's widow sued Giroux for $1,000,000, but she lost:

Giroux experienced another heartbreak in 1929 when Joseph, one of his three sons from his second marriage,
died at age 34. Giroux died at age 78 on June 25, 1933. The following year, his Hollywood estate was sold:

The Giroux Mansion was torn down in 1973; the demo permit is dated August 2. The convent almost closed in
2009,
but the nuns are famous for their pumpkin bread, the sale of which helps keep the place
open. It's really good bread!
This is what the property looks like now. The pink star marks the site of the former Giroux Mansion. Some of the original
stairs and retaining walls appear to still be in place:
