Room 203 disappointment

After being told I could take over room 203 at the university for a day, health and safety problems have occurred.  Due to the room being quite tall I would have to use ladders to reach the top of the windows in the blacking out process, however due to the room being on the second floor it is against the univeristy health and safety rules to take a ladder up the stairs, so therefore I would be unable to black out the window and create a camera obscura. The only option was to therefore look for another room in the university, but this took away the connection of the building site and students relationship to it, basically the whole point of the project. But, I am still interested in students interaction with any camera obscura so I will have to look for another room.
