One question that continues to be asked by people around the world is just how big a project can be before it's absolutely laughable to call it green. The latest mega-project from Dubai stretches the bounds of eco-believability. It's a $54.4 billion environmentally friendly real estate project stretching over 20,000 acres. The Mohammed bin Rashid Gardens has four main clusters themed around wisdom, humanity, nature and commerce. The plan is to have 73% of the total area covered in greenery. Yes, in Dubai, a country that is pretty much a desert. The design as shown in the model above calls for plenty of large lakes and canals.

The House of Nature will have parks, flower gardens, recreational clubs, a zoo, hotels, environmental labs and alternative medicine and herbal healing clinics; the House of Wisdom will be home to a library, international universities, history and science colleges and a mosque; the House of Humanity will include the Mohammed bin Rashid Al Maktoum Humanitarian and Charity Establishment, the Museum of Light, the Human Civilization Museum and other room for other charities such as Unicef; and the House of Commerce will include banks, financial services firms and insurance companies and colleges that will specialize in banking and finance.

Internet rumors have pegged the location of the project, which will be overseen by Dubai Holdings, to be between Al Khail Road and Emirates Road in an area that borders Downtown Burj Dubai to the north and Dubailand to the south. This hasn't been confirmed and no date has been given for the start of construction.
