From Tony House Blog: If a Moroccan tent and a trailer had a baby, and that baby went to charm school, it might look just like the Opera. The Opera is manufactured by the Netherlands-based Your Suite in Nature (YSIN) and was designed after the Sydney Opera House. Read more about the specs here.
The Opera is about 2,973 lbs. and is available in three color schemes. It’s being sold in Europe and Australia for approximately $36,152. If you are on a budget maybe these tents will do.
