I wented and looked at this place last summer. It was suppose to be the first of a small sub-division, a la Agave. Then the market crashed, etc. I am not sure of the plans but I do know that lots were available for bring your own builder / designs.
Cuernavaca is a curious place, a mix of trailer parks, working families beach homes, and multi-million dollar estates. These were along this road that lead to a nice little valley and there were some lots that simply lovely views.
