There is a company located in Karen that is doing houses using pressed hard boards or something - they have obviously given the material a sexier name. Is this the same material being used by this Zen House fellows?
I jokingly told the Karen guys that with the security situation in Kenya, it would not be a good idea to live in such a house. The thugs wouldn't even bother looking for the door. Wanaingia na ukuta. They assured me that the boards are hardened/compressed, fire proof etc. The material is from the US. They have three or four design with one even going up one floor!
I can post details of the company later if anyone is interested.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
