Baldwin & Howell, one of San Francisco's oldest real estate firms, developed Westwood Park in 1916.
[2] From 1918–1923, a series of newspaper advertisements promoted Westwood Park as “an ideal vacation without leaving the city”, and a place where you could “give your children the right kind of a start”.
[3] One advertisement declared "young married people find that the sunshine and fresh air take the place of medicines for their children..."[4] Homebuyers could choose a design for their home from a catalog by the contracting firm of Barrett & Hilp.
The Park was laid out in an elongated oval shape with multiple rings radiating out from a central intersection with curvilinear streets, reminiscent of the Olmsted tradition.
They were designed by architect Louis Christian Mullgardt for Westwood Park developers Archibald S. Baldwin and Josiah Howell.
