I think my favourite design decision that I found in Norway was the choice to label the washrooms as Gender-neutral. Up until this point, I had only seen single occupant washrooms labelled for anyone. I first saw these washrooms at school HiOA (Oslo and Akershus University College of Applied Sciences) and kept seeing them around Norway.
I’m can only imagine the difficulty when sex and gender identity do not align because I have been able to avoid having to pick between two unsuitable options when trying to go to the washroom. I can only try to empathise with those people that don’t fit into the common binary options. It's important to me that we can question norms and strive for design that works for everyone.
Here is another example. This is the washroom for Mesh's cafe. Mesh is a co-working space in downtown Oslo. This one also has an extended urinal.
These washrooms are very similar to ones that are designated for just male or just female with only one difference (three if you include hygiene receptacles in only female washrooms and urinals in male only washrooms): each stall has more physical barrier compared to gendered ones. New washrooms can easily be designed for all and with a little effort, current ones can be retrofitted.
