This is a nice basic construction but you can make your house more elaborate as you get more familiar with the process. Use your imagination and lollies and icing to make doors, windows, pathways and a garden. The gingerbread needs to sit overnight after cooking and after assembly - the fun is in the decorating!
You can trim the pieces to better fit together when you are assembling.
You can substitute egg replacer like "No Egg" for the raw egg whites in the icing.

Altered ingredient amounts. Im sorry but your measurements are all out. Specially with the icing. NOT HAPPY - 05 Mar 2011
I added about another cup of flour and another teaspoon of ginger. I have made three batches of this stuff in the past month for a gingerbread house making gathering, and it's just fantastic (not to mention completely delicious). - 29 Nov 2011
Great. Makes a massive dough, enough to make gingerbread men with afterwards, as i did! - 22 Dec 2010
