Seeing many excellently built building model here, I couldnt resist the attraction of building my own.
I bought Berlin Dome and Frauenkirche Dresden published by Schreiber-Bogen.
For me Berlin Dome is more attractive than Frauenkirche but considering size and number of parts Ive opted for Frauenkirche as adequate for starter of my first architecture building.
The kit consists of 13 A4 sheets and to my delight it has English instruction which I didnt expect.
Thanks to English instruction I learned history of this Blessed Lady Church and the most impressing story is its reconstruction after the WWII.
First cut out basement then cut out walls and windows.
After I had assembled one wall, I knew one of key points to success will be firmly folded lines. If folding is sloppy, corner of columns will tilt. All columns and walls should be right angle to the basement as a matter of course.
And a comment by Ricardo I remember which was mentioned somewhere in a architecture construction report that is to leave reasonable length of paper around gluing tab so that it makes easy to fold narrow gluing tabs.
So, I folded all lines on walls before cutting out window openings, and for windows leave certain amount of paper to make folding easier.
