Responsible for architecture is British Foster & Partners. The villas are inspired by the sand dunes in the desert.
The first building that crossed my mind when I looked at the images of the villas is SLR factory Paragon.
As for the who this extraordinary neighborhood is aimed at I would say wealthy Egyptians with business in real estate, tourism or the oil-industry. Due to the pyramids Egypt has always been a popular tourist nation for westerns. Although there are many there annually, the majority are middle class people and can in no way afford to buy some of properties in the middle east. The only ones who have enough money to buy a summer house in the middle east are tycoons, CEOs and owners of several companies.
