That's a great aviary, Tielfan, very similar to something I have been planning for a long time, waiting for the place with garden I am looking for.
I was thinking of placing it against the house wall so that one of the house windows would open into it, making it easy for the birds to get indoors if they like.
I don't know if that is a good idea, time will tell

This one below is my first cage, the one I bought for Bubu

When Yoghi arrived, they were very good friends and shared it with no problem, even though it's definitely too small for two. I was able to get away with it because they only slept in it.
It's a very sturdy cage and easy-ish to clean but the two feeders are located too low and the birds don't like it at all. The top opens up and stays open with a long perch, they like that a lot!
When I bought Frank I built a very big one, and eventually it housed George, Trilly and Fifi too.

It was all wonky but the birds adored it! The top was a hard plastic sheet that I removed during the day, the two doors on the front were removed during the day too so they could use it as gathering point and playgym.
It eventually had to be pulled apart because it was getting TOO wonky
This below is a smaller version I put together with some of the original panels, to accommodate Trilly and Frank's family
