I recently built my own wooden indoor tortoise enclosure from as close to natural solid wood as possible without actually chopping down a tree, previously I had used the worse possible for tortoise a small aquarium fish tank advised never to by experienced keepers. My tortoise didn't feel comfortable in a glass container or probably plastic which I haven't used, but she seems to noticed the smell & feel of wooden materials compared to other more artificial ones. I added wood chips, small stones, live grass & a cactus plant to make her feel at home & apparently more pleasing to her. I read redfooted tortoises loves to burrow & dig, is adding natural planting unfertilized dirt advised for baby tortoises?
