Hi Isaac. I m coming back tot the issue to place a ‘like’ extra side wall (litte less width) to both sides that touch the walls in my drawing below. I can’t figure it out in Project,   tried with adjusting a filling pannel but i cant work it out and don’t find tutorial on it. I ve also posted a sketchup drawing on the subject before. We like to wor with a cover. 

Also : my cupboards don’t seem tot touch my wall and when i’m trying to move towards it..they stay in the same position :/

The plinth i l be ables to manage i think. 

Kind regards, Bart
