Making a reptile cage with a sliding door. Help? - wooden swing set plans blueprints

I am a big cage, which eventually became the home of a Chinese water dragon or two. The problem is that it would not look like a big cage (48h x 36W 's) that an open-top tank and do not want a big swing.

It is a large acrylic aquarium type cage and tried to build a road to a sliding door.

Can anyone help me or tell me the meaning of some help?

I want doors that slide over each other as patio doors.
Should I build a wood base that the glass can be released?
