A self-contained floating habitat designed to solve the twin problems of population expansion and the environmental degradation of land is under construction in New York.

Named the Waterpod, this floating eco-habitat designed for rising tides was the brainchild of artists artists Mary Mattingly and Mira Hunter and will sail New York's waters from 1 May 2009.

Eco-smart builders in the city commenced work on it last year and will construct the floating home using recycled materials including wood, metal, plastic and fabric on top of and adjacent to an industrial barge.

It will resemble a triple-domed island, measuring 25m by 7m and also incorporate the use of salvaged pieces of sunken vessels raised from river bottoms in the area.

It will be powered by a hybrid solar and wind system.

Waterpod's largest dome will be dedicated to community and artistic activity, the second to hydroponic and vertical agriculture, greywater recycling and alternative power sources. The final dome will be the living quarters.

The unique structure will be open to the public and monitored online.
