I keep all my Shinglebacks in an outdoor enclosure.
I will try and find some pics.
It is very large, heavily planted and 'natural', with lots of hollow logs etc.
I do have some cement pavers in there which absorb lots of heat and they all love basking on them.
They are pretty much able to live exactly as they would in the wild.
I only supplement their feeding as they seem to find plenty of food in their enclosure.... dandelions, snails, insects etc.
