The above and below photo are from the AIA Guidebook for Kansas City Architecture. They show a boathouse shelter at Lake Jacomo...with a stone foundation elevating a viewing platform, and a cool shade canopy...the support struts are reminiscient of Bruce Goff and Albert Yanda. I've been wanting to, but haven't been to photograph this and see if it is still there.
The current photos below show Rocha's design for a park sheltor that was asthetically pleasing, functional and could be built for a consistant/uniform cost. I think this is a great design for a sheltor...clean "view" line, thin roof line, stone structural support with cooking area integrated and large (at least 20X20). Designed and built at a time when "thin-shell" construction was in the vogue. (see Manuel Morris) It was apparantly successful as a sheltor design, you can see these structures in many KC and Jackson County parks...these photos were taken at the Water Tower Park located at 75th and Holmes in KCMO.
