The plaster is made in Japan & I found it through a local supplier in California. The mix was sold in 5 gallon containers and all you had to do was add water before applying it to the drywall.
My take on plaster is that it does little to insulate - unless it's applied over insulated drywall.
Hope this helps!

thank you very much for your kind and timely reply
Ubfortunately I will not be able to use it in pakistan as it is not available here

but still the colour of the plaster is very absorbing and nice

What kind of wood is that? Cedar?

Yes it does;) thank you..would you mind me asking what the project cost was?

Hi, Richard.
I designed this project about 3 years ago, so I don't really remember an exact number and I was only involved in the design side of things.
Between all the elements: design, wood work, shoji screens, bamboo ceiling panels and plaster I would estimate this to be over 10K.

Do you know is i could get that wood i the usa?

I would love to see the front pic where the barrel ceiling ends:)

Hi, Richard.
I don't think you can get the wood in the US any more - you will have to check with your local supplier, though. Maybe use another species of cedar?
Regarding the opposite wall - I don't have a picture. The frame that supports the ceiling structure is exactly the as the opposite wall.
