S.B.
We did one over Thanksgiving break. It was fun and not THAT much harder than the kits.http://www.simplyrecipes.com/recipes/how_to_make_a_ginger... That's the site we used. And I chose this site because it was referenced in three blogs I read.
The recipe worked really well, but I did have to add just a bit of water because otherwise, it was a bit crumbly. Someone on here gave me the good advice to put the template back on top of the house while the pieces were still warm and trim for sharp edges.
We didn't have to make any sort of structure at all. We made the dough two mornings before THanksgiving. The day before Thanksgiving we cut it all out and baked it (didn't take very long at all...maybe an hour. I just cut the pattern out and put that directly on the cookie). After it cooled we glued it together. We used the Wilton recipe for frosting. We just went slow. Glues two sides together. Then the other two. Then put those four sides together. ANd then we used the frosting to fill in any gaps or holes. We used Halloween candy to decorate.
I thought it was going to be a much harder task than it was. When I asked about the dough on here, I had a few people suggest I just go get the kit. In the spirit of full disclosure...I am a cake decorator and I do a lot of baking, but I have never before made a gingerbread house. WE have bookmarked the page and we will make another next year. For us, it was a great project.
Good luck!
