Do you mean plans for construction? There are many sites on the Internet that will have samples for you. The main issue is that local ordinances require setbacks from property lines and these free samples may not fit what your local building department may require. You can usually access the setback information from your building department online, but a trip down to talk to a planner may be necessary. Start there, finding a house plan that fits within that footprint is the second step.

Do they have to be paint buckets? I would think they would not be good for gardening? Maybe others will know more about that. But in the U.S. you can get 5 gallon buckets from some local businesses like bakeries, food store chains, places like those that regularly use items they get in the buckets. For instance a bakery usually gets stuff in 5 gallon buckets and often has to throw them into a dumpster as they can only save so many. Some businesses now sell them for a small fee, maybe 1 dollar U.S. each and some just give them away. I think the cost of shipping them to India would be more than the cost of buying them. You could try setting up a fund on Kiva.org and possibly get enough donations to purchase food grade buckets instead of using ones from paint. Good luck with this project and please update us as to your progress.

As Mr Raghu has commented, designer pieces (in whatever category) are not for ergonomics or practicality for normal use. This one is a famous design by a group of professors at the Victoria University of Wellington, New Zealand to aid Autism. You will have to order a piece from New Zealand to be true to its purpose. Copying can be done by a skilled carpenter in India, no doubt, but would still be expensive and a fake. Expert from Inhabitat website: Cradle is a sustainable rocking chair created by a collaborative effort to aid people with autism and Rhythmic Movement Disorder (RMD). Developed within the Victoria University of Wellington, this cocoon-like seat is made from cold-bent plywood. Because rocking is one of the calming activities that is recommended for autistic folks, this special seat is a soothing and aesthetically pleasing addition to their homes.
