Surprised the tree one isn't available to purchase with crowns in the housing editor already. The potted one is a nice reskin of a craftable one from Markath dlc.
Sadly housing got a really small selection of craftables this dlc. There will be structure related ones coming soon, and I think pc just got a set of gold blueprints added. But it still pales in comparison to the share volume of stuff that dlcs like Morrowind, Summerset, Elsweyr and Skyrim added.
