It's beautiful, but maybe you could remove the roof of the castle? Tortoises want an enclosure with a lot of space to roam and a few small hides. The big dark castle looks cute, but it's not useful for Squirt and the enclosure looks quite small, so it would be better to make use of that space.
The top comes off so I can clean it and get se light it's mainly a bed area he's a hermans tortoise so he's only small and it's a big table bigger than the one he's in now
That substrate needs moisture. It's too dry. Easy quick fix there.
The raised area the castle is on, the balcony, is that area all accessible to your tortoise? Make sure he can't get stuck.
It's a very cute design, but not space efficient. About 1/3 of the bottom floor space is wasted as a closed box. Can you make an opening into it so he has that area as a hide, too? The raised area isn't additional space at present. Something else to think about.
I have had 3 people ask me the same thing
To start with I would never build a small cage for my tortoise and have allowed growing room.
The box the castle is on is a draw for all squirts food and stuff so it's in one place.
Overall the new table is nearly double the size of his current one so I don't know why I need to leave more room when he's getting it anyway!!
Also the photo of squirt was a month ago and just before I changed the table substrate
