Whats behind door number 1?

One of the potential buildings I have designed for my client the house in effects I one large atrium. There for making it rather difficult to hide or conceal a door that leads into his research lab. So I have designed a secret door within his kitchen wine closet. When the wine closet is opened it will look like any other wine closet, but lift the Chteau Haut Brion Pessac-Lognan 1982 up and down twice and the wall is lowered into a special slot in the floor leaving my client direct access to his home within a home.
