Please I really need your opinion!!. Hope you enjoy it!!

Personally I think the space utilization can be improved on the first floor. Look at the narrow passage way where the toilet door is. Personally I would rather not have the passage way. I would expand the toilet space up to the kitchen wall. The toilet door can be placed on the other side facing the staircase instead.

Also, what is the purpose of glass on top of every door in a modern era house?
