Some of my most read posts here are about building domes. My YouTube video called “Survival Shelter—Inexpensive Geodesic Domes” continues to prompt comments and questions.
That video grew out of a post entitled “Domes from Karl.” It contains the text used to make the video. It may help you to see the info laid out in writing. You can also view the video itself there. Plus, there are a couple of links below the post you may want to check out.
To answer a question I’m asked most often, I don’t have a set of plans for building a dome. That’s because much depends on what you’re planning to use a dome for, and that will determine the size and configuration you need. You’d likely be unhappy if I offered you a “one size fits all” plan.
However, some general concepts should get you started. For example, here’s a tip about construction. If you cut a 10 foot length of PVC in thirds, you can multiply that length by 0.884 for the length of the shorter pieces you’ll need.
Click here for a geodesic dome calculator. There you’ll find the means to calculate for 1V through 6V domes. Type in overall dimensions and it gives the struts you’ll need. You can even start with the strut lengths and it calculates the other way.
If you’re looking for a thorough reference book, get Geodesic Math and How to Use It, by Hugh Kenner.
Also, you can manage construction more easily if you color code your short and long struts near the ends with colored tape or paint.

For something a little different, Illustrated Dome Building: Step-by-step Complete Plans, by Gene Hopster, describes building a hexadome.
