...do you have already a sample of carpet that you will use in V2?
Stay tuned my friend... very soon  
 OK, now the job the day is to sand all the joint between the plaster boards. I know there will be a lot of dust, so let's close the access to the 
original lair  
  

Did you see the joints... that's what I've to sand  


Let's try the 'manual' method first ...

Jesus  

 It will take ages  

 OK, now the electric version  
  

Faster of course  

 OK, it's done  

 :

Remember, I've used plaster boards ONLY for the common wall between the two rooms. For the three other walls, I've used wood boards.
Some screws really bore me like this one  


I can't screw on further than that. OK, let's remove it, and make a bigger hole, like that :

Now I can push it  
  

Hopefully, I don't have to do that job for all the screws already fixed... but I did that for maybe 20 or  25 of them  

Anyway, it's completely done now. I just have to cover the screws + joints with this  


Done :
