If you followed our progress throughout the One Room Challenge, then you know that the boys didn’t even know this space under the stairs existed. We previously used it to store our Christmas tree and a few other random items, so there was never a reason for the boys to be in the space, and they had never shown any curiosity or interest in what was behind the door. In order to keep the secret, we worked exclusively during nap time, after the kids were in bed, and when the grandparents could babysit.
