The first example looks pretty unique for an art style. I'd love to see this done on the fly, so that each building is unique during game play.
Also, I think the buildings would look better if you give it some context of the ground surrounding the buildings.
This certainly solves a lot of issues for tile-based games where you have to handle at least 3 cases in both graphics + programming (in a 2d, single-layer tile game, you need corner pieces, middle pieces, and edge pieces). Think two houses built next to each other in AoE - now they could mesh and form a completely new style of row house, without any effort
