Fantastic setup - really well done! Here in Sao Paulo, pizza ovens are very popular, although I am ashamed to admit I have a pre-mold concrete job, and wished I had done a proper brick job.
The hardest part was perfecting the dough - I still haven't found the recipe I really like, but it's a lot of fun experimenting. The best thing about the pizza oven is that everyone joins in - it's very interactive compared to BBQ - I have also done some great lasagna and breads in the thing.
I plan on re-doing the BBQ house - it's going to be a setup like yours, with a proper Pizza oven, the BBQ pit, an Argentinean 'Parilla' grill for cooking over wood at closer range and a Brazilian 'Fogo a lenha' which is a wood fired hot plate like this:
Anyway - fantastic job, and I can't wait to hear more about your pizza success stories and some photos of the food please!
