Hi There! Welcome to the forum! Pooham is lovely
Where bouts in the South East are you from?
I had the Peggy Metro cage as my Syrian's first cage (it's the same as yours but with tubes going up and round the top) and decided, like you, to get a bigger cage and more room for toys.
My Mo was a bar chewer, so I also considered that when buying my cage - I went for the Duna Multy

Mo loves it...it's got good floor space for running around, and fits a good amount of toys (even more if you get things that hang from the roof.
However, if Pooham is not a bar chewer, you might want to consider a larger wired cage and I'm sure people will have opionions on which is best! Also, the Duna might be a bit big in width if you have a small area...might be better to go for a taller cage!
Anyway, I'm rambling and all I wanted to say is welcome!!
