We have a bird aviary (although it could be used for any critters I believe).
It is now surplus to requirements. (The previous residents now having moved on, and we have no plans to replace them).
Flat top roof
Dimensions are 150cm wide x 127cm deep x 178cm high.
The wire spacing is 1cm square.
Green Zincalume.
Lockable door.
It disassembles into small sections, about 30cmx178cm.
Pick up only at Tuggerawong on NSW Central Coast.
It is still assembled so some time to take it down will be necessary. (This should give you a good idea of how to put it back together.)
Additionally, original assembly instructions are included.
