18w11a Villagers don'r breed. Golems do not spawn

Built a small base for snapshot tests/exploration/survival.

Found out that villagers don't feel like breeding no matter how many doors i have in the area.
Perhaps i am doing something wrong but i am pretty sure i am doing it right (see screenshots below)

Built the villager hotel so they would breed - no result
Tried spawning a lot of villagers via creative mode to get the golems to spawn - no result
