Inspiration

Hi there As a new user of Home Designer Pro (purchased July 2014) I thought things were going well until I realised I had forgotten to add the level change on site. Now my main house has been lifted 550mm but when I re roofed it the walls stopped reaching the roof and now the glass doors are coming through the roof. Apologies if this is a very simple mistake but I have cruised the videos and help faqs for a few days and getting really frustrated. Thanks for your time.
