Thanks for all the positive comments guys!
@ Snapped - There is an air vent at the bottom on one side wall and the top of the other side wall - just realised you can't see them in the pics. Also, where the glass doors cross over at the front, there's a 10mm gap all the way down the front of the enclosure - that's why I had to put my BHP in there 'cause he's huge and no chance of escape!
@Crazy_Snake08 - I haven't really thought about doing anything differently, I'm just really pleased with the way it turned out - it certainly is a conversation piece when people come to visit! I had a vision when I created it and it turned out exactly the way I wanted - if anything, I would have liked it a little deeper, but I had to work with the space I have. A deeper enclosure would have allowed for a larger strangler fig to more completely fill the enclosure - but the bigger the strangler fig, the wider it is. As for having the doors open up into the hallway, I really don't think I could get hinges that would hold the doors they're so heavy and an adult does not really struggle to open them. I think I prefer them sitting in the tracks and at least that way, their weight is supported evenly along the bottom. My 11 & 13 year old kids open them with a little effort but they really do not bother me - other than having to wipe the fingerprints off every time we open & close the doors!
