Here is the link to Dale Naegle’s website, with the story and photos during construction: http://www.dalenaeglearchitect.com/Site/Pavilion_Story.html
In 1960 Sam Bell heir to General Mills (Bell Potato Chips) purchased a summer home with a spectacular view of the Pacific Ocean. His property extended down a 300 foot cliff to the mean high tide line of the surf below. His beach is isolated 4 miles from public access to the North, and is accessible only at low tide through rugged, slippery rocks from the south, and remains unused and out of sight. Only surfers 100 yards away can see the mushroom shape of the guest retreat.
