Would converting a storage shed into a functional insulated bedroom for our oldest daughter be a viable solution to our current living space issue?

My husband and I have been kicking around an idea as a possible solution since we can’t afford to move right now. What do you think about getting a big storage shed and turning it into a fully insulated and functional bedroom for our oldest daughter? We would connect it to the house somehow. She really needs her own space, and we’re at a loss for other options right now.

We love our neighborhood and don’t want to leave, but our house is feeling cramped now that we’re a family of five. We have some great ideas to improve the rest of the house, but this bedroom situation is really frustrating us.

Do you think this shed idea is a bad move? Could it cause issues with CPS down the line? Thanks in advance for your honesty.
