1927 fountain plan by Hale Walker
The garden as a whole should express the feeling of an outdoor living room, and as in a living room one usually has two especial points of interest—the hearth with places to sit grouped about it, and, if one is fortunate enough, a view from windows…The hearth in the living room becomes the wall fountain in the garden - Hale Walker

Hale Walker worked in the landscape architecture and planning firm of John Nolen and assisted Nolen in developing the comprehensive city plan for San Diego in 1926 that George Marston had championed and helped finance.

During this period when the firm was developing the city plan alongside one for the city's park system, as well, he was commissioned to design the Marston house formal gardens, based upon the preliminary drawings of landscape architect Thomas Church.

This 1927 plan by Hale Walker shows the construction details of the wall fountain in the formal garden.
