Currently in Loreto, construction is not only active at Loreto Bay. From our last trip in September 2006, I have footage of at least a dozen homes being built in Nopolo (Nopolo is the neighborhood south of Loreto where Loreto Bay is being built). In this clip we can see the foundation of a house being built in Nopolo.
House Foundation in Loreto, Mexico
From what we've seen almost all houses are built the same way: you can see a ditch 5 or 6 feet deep, which is then filled with concrete. From this foundation, long and thick metal wires help define the walls and rooms. This clip is a bit over one minute; there's a friendly dog bugging Janelle, but I thought that was funny so I left it in.
