Katherine, a reader of my blog asked me about sharing the pattern for a house I made a couple of years ago. I made about 4-5 houses with this pattern.
I make my houses out of cardboard to make them strong so they will last for many years, but there are a number of people who make their houses out of card stock like this. With paint and glitter and a firm base they are surprisingly sturdy.
The front gable extension pattern can be greatly simplified as well.
I've shown a side view of template taped together to show you that the extension gable is better supported this way. It is much easier to glue on a roof piece with these flaps in place. You may still have to cut the tab pieces a little bit depending on how much light you want to enter the extension.
