ASCII Art Octagons

Given an input integer n > 1, output an ASCII-art octagon with side lengths composed of n characters. See examples below:

n=2
 ##
# #
# #
 ##

n=3
 ###
 # #
# #
# #
# #
 # #
 ###

n=4
 ####
 # #
 # #
# #
# #
# #
# #
 # #
 # #
 ####

n=5
 #####
 # #
 # #
 # #
# #
# #
# #
# #
# #
 # #
 # #
 # #
 #####

and so on.

You can print it to STDOUT or return it as a function result.

Any amount of extraneous whitespace is acceptable, so long as the characters line up appropriately.

Rules and I/O

• Input and output can be given by any convenient method.


• You can use any printable ASCII character instead of the # (except space), but the "background" character must be space (ASCII 32).


• Either a full program or a function are acceptable.


• 
  Standard loopholes are forbidden.


• This is code-golf so all usual golfing rules apply, and the shortest code (in bytes) wins.
