We call this a fan arbor, and isn't it a unique structure? This arbor was designed by the architect James A. Johnson who works out of the Del Mar area. It is 24 feet wide and 25 feet deep, and 11'10" at the highest point.

This is a clear redwood structure. The 3 beams are all laminated,the longest one being 24',
and the shortest 8' 7".

The posts are also laminated redwood, and turned to a slight taper. The Post/Beam connection is a pegged hardwood dowel.

The posts are set into 36" deep concrete footings whose tops are slightly sloped above grade. A 4" wide copper band goes around the post at this vulnerable spot, protecting it from rot.
