Ecological home of Sanjay and Pratibha Singh
“The artist couple Pratibha and Sanjay Singh have a nice earth based ecological home along with a studio for Sanjay as part of the home. The whole house is of earth excavated from the site. There is no plastering or painting for the building. The house is naturally lit and naturally ventilated with no fan or air conditioning. Sanjay is an avid gardener and we josh about his North Indian garden. Harvested rain supplies the garden water and adds to the house hold use. Grey water from the kitchen is reused for the garden.

Pinterest does it again. This site never ceases to amaze. Pinterest is so good that I have to be careful not to spend too much time there or other things won’t get done. They seem to have endless high quality images of every imaginable topic, although as mentioned previously there’s no convenient way to search their site, so I use my favorite search engine.
