Brian and Jason Lyles have released a new book, available on Amazon, that should be on the coffee table of every AFOL. This 200 page paperback, The Lego Neighborhood Book, will train you in the fundamentals of recreating popular architectural styles in Lego.
I am a huge fan of the work that Brian does on Brick City Depot. The site has tons of parts lists and building instructions for the creations that he and Jason have made over the years. I've even done a few of his alternate builds that utilize the elements in existing Lego sets to create something new. This book features some really handy construction tips and mini-builds that are sure to fortify your technique.
