If anyone's interested, I made a simple mod to allow you to just play the mansion repair game without the rest of the story (it's just for a bit of fun, it's not going to integrate into your main saves).
Just thought that since episode 9 is coming out with the new, hopefully excellent, party planning minigame, and I know how many people enjoyed the mansion minigame, others may like this too.
Two ways to do this, make a copy of your entire game, download the zip file and extract it into the "game" folder of the new copy (don't put it in your original game folder otherwise it'll fuck your shit up). It may need to overwrite a just a few files. You may also need to delete the "cache" folder in the "game" folder if it doesn't seem to work.
After that, just run the new BeingADIK.exe.
If that sounds too complicated, you can download
this MEGA Zip. It contains all the files you need for a complete standalone run of the mansion mini game (it probably has a bunch of unnecessary files, but it's only a couple of GBs).
