hey all
i was thinking that for our columns, they don't actually need to be 300, we could just have 150, but maybe for the interior columns we go up to 300, just to be extra sure it will work. also on the ground floor we may need to have two rows of tubes on the exterior walls, one row to support the floor above and the next row to go all the way up, cos otherwise we will see every now and then a tube stoping, supporting a beam or lintel and starting again. which could look messy, or interesting depending on how we treat it. let me know thoughts on this... as in the mean time i'll work on both.
