Winery Danuolla (Dishonored)

Hello! Decided to once more go through the game, trying to pass all the missions 100%. In General, on the second mission I came across one interesting room at the winery Danuolla (on the instructions of an Old Rag). The poison I have put in pseudomys, and found the lower floor room one. Inside are two pustkowie things, but I just can't pass the game on, not once inside) does Anyone know how to get in?

Doors and hatches into the room no, levers and other devices I have not found. Special vision also can not see anything, other than 2 items inside. In General, help!

If nobody knows the answer to another question: is there any cheat for passing through walls? At least so goes inside, suddenly developed so to make a joke and decided to get inside is unreal =) In General, waiting for your tips!
