I have a new video for you today. Shortly after the Logan Temple was dedicated it was decided to expand the annex to add more area for the administrative side of things. Additionally, a new entrance was added on the east side of the annex. This addition was to help shelter the original entrance from the bitter winds in the area, especially in the winter. This two door setup is similar to the double sets of doors seen on many temples and other buildings today.
Also, as a side note, I am in the process of migrating all of this from 3dtemples.photogent.com, to just photogent.com. So watch for all kinds of changes over the next few months.
