The longevity periods you have indicated… I guess you are referring to iron sheets used for roofing,since they are exposed to the vagaries of weather directly.. RIGHT? and I guess this should apply to any other structure as long as the roof is in iron sheets…Otherwise me thinks Mabati used for walling should last at least a lifetime as long as they are painted and shielded from rain and direct sunshine..
Thanx for your insight,your site is creative & offers some interesting info…
How much would a standard foundation for a one storey structure cost per square meter? Assuming red soil?
