Tort Towers (almost complete) & a question or two :)

[tinymaze]

hi,
great looking table you've made , i was looking at the extra deep bookcases in Argos are they any good? how's your's holded up? I've got a book shelf from them before to use as a bookshelf lol, but the back was very flimsy was it ok on the deep ones or did you have to put something else on? im rubbish at DIY so looking at a cheap but affective way to upgrade my two's enclosure,

I bought an extra deep bookcase from Argos once to use as a tort table (because I think someone on here said they'd used them) but the back wasn't strong enough to hold the weight of the substrate, which was a shame as it was a good size. I suppose you could always strengthen it with more wood or something...

where did you get the top part from?
i'm also thinking about making a second teir for my tort to roam
