From Simply Recipes:

I like the Simply Recipes resource because it’s from a personal blog and includes good photos and detailed instructions with lots of helpful personal tips. I also like that – by virtue of being written by a person baking at home, not in a professional kitchen - the post includes normal baking photos. Meaning, the author shows broken pieces (and tells you how to fix them) and unevenly baked edges, yet the final result is cute. It’s a good reminder that the process need not be perfect – you can cover any problem areas with decorations. Templates are included.

From Cookie Magazine:

Cookie offers a more streamlined how-to, best suited to experienced bakers who understand baking lingo and process. What I think is really cute about this post is that they include templates for a brownstone, ranch house, and garage. Perfect for urban and suburban representation.

From King Arthur Flour:

King Arthur Flour offers a somewhat insane 14-page PDF guide to constructing a gingerbread house, but it’s a really handy reference for first time builders and novice bakers in that it includes a ton of annotated photos to help you navigate the baking and construction process. The decorating photos - including trees cleverly built on ice cream cones – are impressive, and templates are provided.
