I have a bit of a question.

slowclayman was banned a while ago and it looks like he is going to stay that way which is why im typing this.

one day he was bored so he asked if he could help me with any thing so i said he could help build a pokemon center next to my pokemon arena. so my question is is can i take down what we built, all the materials were gathered by me or payed for at my expense there for i feel i have the right to remove it, do i?

Yup.
It's yours, go for it.
