This book contains templates for 20 self-contained paper buildings for a Hogwarts castle complex- some of them even have a fully furnished interior and removable roof, like the Gryffindor Common Room and Dormitory, the Great Hall, the Owlery, Hagrid's cabin and the Staircase and Entrance Hall! Some of the buildings have been designed with identical measurements so that even parts of them can be mixed and matched for more variety. All buildings can stand alone or be put up as part of the castle complex. The templates were hand-drawn with a quill and ink from a bottle in a process taking several weeks, which gives them a unique quaint and personal touch which cannot be achieved with computer-assisted design. The buildings are in black-and-white and can be coloured in according to individual preferences.
