most of manifactured lofts are crap i know i bought one , why aint there a loft building company building out of sheet marine plywood ???? anything with toungue and grove eventualy leaks especialy if knots fall out or is made with unseasoned wood , i bought mine as need it it quick buy in haste and costs you far more long term , will be building next one mesen might take a while but be 100% better than any pre bought lofts
