Developing in Casco Viejo is both a science and an art. Experience and common sense have to blend with the historic restrictions and be sensitive to the environment. It is a complex process that we only recommend to people who have the correct skills and team behind them, and that will be on the ground full time for at least three years. While most of our clients might feel this is too much, every year I see examples of what can happen if something goes wrong. Yesterday, we witnessed a very sad example of lack of planning and the most basic common sense, which led to the partial destruction of one of Casco Antiguo´s most valuable icons.
