I've had quite a bit of contact with this company over the last few months.
From what I can gather, Las Torrentas came about when the company owners (already property developers in the UK) were looking for holiday home in Spain. They got so sick of all the sub standard properties and huge builds, that they decided to put something special together with no catches, is good quality, or the usual extra costs that you normally find while buying in Spain. According to the brochure I received, the development is in protected area too, so won't end up in the middle of a concrete jungle.
I'm seriously considering buying out there.
