Improved Tiny Hut

I made what I think is an improved version of Tiny Hut, by giving it improved abilities as it's cast at higher levels, with the goal of it eventually ramping up to Magnificent Mansion. It is currently flavored to seem like a witch's hut.

I've made a lot of homebrew spells, but this is the first one I've felt was worth sharing with the community. Please enjoy in your own campaign and feel free to let me know what you think:

Does it have a solid floor? IE is it a dome or half sphere?

Can it be moved at all?
