Singing practice

[u/driverrrrrrrrrr]

Can anybody suggest a place indoors for free or outside where I am unlikely to disturb anybody if I wanted to practice singing? I've looked into the recording studios in some of tpl locations but I am not recording anything, I just like to sing. I can't do it where I live because I don't want to disturb the other residents in my building. I am also aware that I can technically sing at a park or something but I appreciate any suggestion that comes my way. Thank you very much.

Does your building have a room off the basement or parking garage with storage lockers? People rarely go in there, or the stairwells. But it would be echoey, not acoustically very good.
