Answer: We have a book here in the NGA library called "The Backyard Builder", John Warde, ed., Rodale Press, 1985. It has plans, materials lists, etc. for a large number of lawn and garden building projects, including a wooden window box. You might check your local library to see if they have this book (or ask a bookstore to order it for you). There are probably lots of others available as well. Check the gardening and do-it-yourself sections of libraries and bookstores.
