When I first arrived in Taxco, I watched in amazement as a one story building on the street side, which revealed a three story caved-in structure on the back began to be transformed into a beautiful multi-story edifice with covered balconies and beautiful views.
Quite the transformation right?
What is even more amazing is how the work is done — by hand! There are no cranes to lift bricks to the second, third, or higher floors, they are carried there a few bricks at a time. And if you need supplies delivered to an inaccessible location. Where there is a will there is a way.
Cement is mixed by hand, put into buckets, poured into the forms (which were also created by hand), and so it goes, day by day by day, little by little, one brick at a time until eventually walls, and doors, and balconies appear where there was only air.
It took three years, but now there are some mighty fine looking rooms (habitacions) at the Hotel de Mineral de la Taxco ready for occupation.

I’m impressed! That scaffolding was scary! At least I would be scared! No OSHA there! They sure work hard! No modern tech there! Just heard work and sweat.
You should see the “stairway” to the roof int he house across the callejon (another post)! Definitely no OSHA, but if you do not have your permits in a row (or pay the “fine” the inspector demands,) your building project gets shut down. It is fascinating to see their ingenious ways of getting things done.
