Glass block - typical wall details
I am a new member and am looking for assistance for my final term paper. I am a student studying Architecture in Ottawa, Canada. My project is to draft a wall detail of Maison Hermes in Japan, by Renzo Piano. The building is constructed of steel frame and glass blocks! The problem is I cannot find any information on the wall construction of Maison Hermes OR steel frame and glass block walls in general.
Any information or guidance to help point me in the right direction
would be greatly appreciated.
Thank you for your time and assistance.
