An award winning conservation project: the royal Hacienda Zotoluca was funded in 1570, largely remodeled in the 17th c. Spanish Colonial (the front) and again in the late 19th c. in the neo-gothic (the back). Hidalgo, Mexico. 
The whole project is shock full of details, everything that wasn't salvageable was simply redone, in much the same way it would have been made in the first place, 1570, 1670, 1870.
I love the spirit shown here. Detailed drawings on paper, then rough sketches in real life, and of course, a proper check that the whole thing is to the human scale. This is master class, artisanal, building.
The hacienda style, with its central courtyard and built using only local labor and materials, is of course the original ecological architecture. Sustainable and working with the climate, not against it.
This is one of the original details of the hacienda, a portal from 1710: brick, stone, lime plaster, wood, iron. All materials in perfect harmony and exactly in their right place. The original would have been far more decorative, but here they left it as it is, as it is perfect.
