Altar question.

Hello hello closer witches!! I've been craving to make an altar for me, i feel like it would make spell works and witchcraft in general more pleasant for me to do, and it would make my house feel more like home by having it in. But we have a little problem, i come from a very strict Christian family who visits my house very often (every other weekend).
I wanted to know if there is any problem for me to remove my altar during those weekends and if so, how to remove them respectfully.
Thank you for listening!!
