The oldest primary rainforest in the world lies within commuting distance of Kuala Lumpur, and its 'natural ambience' is seen to offer a 'viable alternative living opportunity' for those stressed by city life. This development (covering 1'400 acres of secondary jungle within the 7'300-acre rainforest) is intended to show that human habitation can be provided in a sustainable way with minimum negative impact on the environment. The low-rise buildings utilise local materials - recycled stone and timber. Access roads follow natural contours to minimise the cutting of slopes. The primary rainforest is maintained for educational and eco-tourism purposes.
