It's a wedge shaped lot, about 750 sq.
Construction here is extremely challenging.
Under Mexican law you, as the property owner, are the employer of all your construction workers. No matter that they work through your architect. It's a bureaucratic nightmare. Easier if you speak really good Spanish of course, but still difficult. You can of course sign a power of attorney to your architect to handle these matters, but then you won't really know what's going on and are quite vulnerable.
