If you want your character to use them for anything, just drop a note saying what they're using it for, and add a bit of a description of what they are putting in there.
(for the buildings I mean)
new calendar will go up tomorrow sometime, I am too sleepy for it now
.. i still don't know where Moon is sleeping
So that's a total of 19 new buildings we just got.
/looks at map
Suddenly it's a little crowded here
RadiantWingedOne well there's plenty of houses now
there are! Just.. nothing like what he's lived in. :|a
OH RIGHT I STILL HAVEN'T POSTED FOR PATCHOULI LIVING IN THE LIBRARY
/AN EMBARRASSMENT TO RPERS
some of the cottages are still undefined
So many choices
you can say one of them looks similar to a building he's seen
XD A tree grown with rooms?
or he lives in the camp grounds >.>;
the A-frame is near the Pokémon Daycare and the river, if you're wondering
well, 18. Since housing 9 and building 7 are different floors of the same building
don't forget there are 3 campground buildings
oh right those
fff
so yeah people can live outside now and still have access to showers
if they don't want to onsen
that clear tent tho... why would you want a clear tent?
Exhibitionism? 
I found some really weird tents while googling for pictures of tents
I wanted to include the tree tents but there are not enough big trees for them
okay but imagine. imagine: giant donut trees
with tents in them
..donut-shaped tents
aoi would move immediately.
they actually exist
Aoi do we need to have an intervention?
SHE DOESN'T HAVE A PROBLEM
SHE CAN QUIT ANYTIME SHE WANTS
I think an intervention is needed
... moon likes that tree tent
And for the curious: 
where all that new stuff is
still need to find out the location of the Salon, but other than that it's pretty much done
it looks so cool |D
... acutally i know which he likes /rolls off
