Hi was just wondering if i would be able to put/use my gym work bench and dumb bells in the loft. The loft has been partly converted prior to moving in. I don't know anything about loft conversions so i'm not sure if the joists get changed etc but my loft has the original joists and the floor is about 1inch and 1/4 ply wood and carpeted. The previous owners had it as a bedroom with wardrobes and bed etc for their son but it could not be classed as a bedroom when we bought the house due to no proper staircase etc. The weight of my bench and dumb bells are about 200kg in all. Is it safe to use the weights in the loft?
