Here's a non exhaustive list of resources and reading material that I used during my investigations and during the build

Forums & Wood Oven websites

Traditional Oven a website dedicated to wood fired oven construction with a lot of technical details
Fornobravo: This is a brick oven merchant website, but they generously offer dome shaped brick oven plans for free (which they call Pompeii ovens).
However, the most valuable thing on this website is the forum where people share their experience, ask questions and give advice, among them some experienced professionals with vast knowledge in construction and materials.
La Confraternita della Pizza An Italian forum dedicated to 'forni a legna' (wood fired oven) construction.
Uk wood fired oven forum: another forum with a lot of useful info and advice from other builders.
Truebrickovens website and blog: dedicated to traditional brick ovens (by David Neufeld, a professional brick oven builder). The blog contains interesting information about oven construction including a lot of photos
