Is a trellis what you want to build? These are fan shaped or other shaped structures for vines and climbing flowers to grow on.
I think that you might want to search using an internet search engine like google for plans of a kind and design that you want to build. Another way to search is to look through the plans at http://wickswww.freeyellow.com/ There is a block to click on the left side of the page with links to many plans sources.
When you have decided what you want to build, let us know if you have any questions about the specifics of how to do it. Also, be sure to choose a wood that will last in the weather. Common pine or white wood will not last but a year or two--at least mine didn't years ago.
