Permission denied using PSCP, Raspberry pi. Special permissions?

Question

I keep get what follows when I try and use pscp to transfer a folder using -r.

pscp -r -P 22 -pw password C:\test pi@111.111.111.11:/home/pi/stuff

And I keep getting -

unable to create directory /home/pi/stuff/test: permission denied

A couple other links say to add permissions to the specified user, pi in this case, [read here][1] but I was unsure whether www-data was a situation specific group that I simply was unaware of or something else because that did not fix my issue. Others suggested that sudo permissions needed to be granted but that didn't seem reasonable either.
