Investigation scene - re-shoot Room change issue

Once we had filmed or first shoot in the conference room we were unable to use the room again, as the room was not free, this ment finding a new place to shoot or scene and reshoot a lot of the scene as we did not finish when we used the conference room.

However we asked if we could use the English staff room for two days in the week and the head of the department said yes so we will be re shooting to get better lighting and more shots.
