I own an original Visalian. The difference between the Seaside is the side wall and attic with windows.
I purchased this vintage house last year. Every shingle is spaced by a credit card. The floors are custom made. I treasure the workman ship and really like that the layout offers another dimension beyond each door.

The side view of one side.
The dining room view looks through the entry to the living room. The wood arch was an optional add on. The builder bought all the options. I have the catalog.
The upstairs porch with custom stained glass windows that have back lights.
