i've been to the one near manazel. buildmart? it's a showroom and they don't actually stock materials, i think.
i was hoping to find a neighborhood carpenter who will have a few pieces of wood around? there must be one somewhere!!
As far as I know, Al Nooh is the main timber yard in Bahrain. I believe you can also buy it at the Builder's Supply store (near Manazel) in Isa town. Other than that, I am at a loss..
