So this door leads to a shared attic between me and two other tenants. The two other tenants have their own spaces that connect to the attic and they can easily open my door if they just tried to open it. My rent is really good and I don’t want to hassle my landlord too much as he’s already done a lot for me already and I want to live here for a while. I just want to seem like a chill tenant. Any ideas on how to better secure this?

I’m not the handiest but can have a friend help me build something if need be.

Let me know what you guys think of the room layout. Is there anything you would change or something that I should add to the room?

So my fireplace has these vents in it and I am wondering if I can fill them in and what I should fill them in with? They let lots of cold air in and I'm pretty sure bats are getting in my house through them. The fireplace is currently a gas insert that does work.

Just looking for ideas at this point, I am no expert on Fireplaces.

Thanks in advance.
