Depends on how solid the joists are and if they're not full of worm or rot! Guess you may find out.

There are a lot of factors that contribute to how much weight a bedroom floor will take.
The thickness of the floorboards The material (the precise type of wood, oak, pine etc) the floorboards are made of The thickness and material of the joists How far apart the joists are The age and condition of the boards and joists How the weight is to be distributed on the floor - a concentrated weight will break a floor that a more dispersed weight would not - a box with a flat bottom distributes the weight better than the point load of something like a bed leg. 2006 building control stipulates 40lb per square foot, that is not the breaking point but a safe limit. A 1930's house will probably take a lot more weight if the floor is in good condition. Easy rule of thumb is if the floor does not creak now but it does with all the extra contents you are probably close to the limits. Good luck converting the house to a bungalow

The problem isn't one of collapse. You could probably put whatever load you like within reason on your bedroom floor and the joists won't immediately collapse. The main problem with over-loading is that it will cause excessive deflection, which in turn causes damage to plaster on the ceiling below.
Saying that most houses built in the thirties are very strong and the joists fitted are sufficiently robust enough to take more weight than modern build houses. Remember in the thirties most people had iron beds and furniture was solid and heavy not like this light or particle board furniture we buy now, so houses were constructed to take the weight of the furniture of the period. Older houses used the same span joists in the bathroom and an old cast iron bath full of water and a person caused no problems with weight. Most Modern homes that use lighter construction materials now have double joists in the bathroom. I do not think you will have a problem at all, however if you notice hair line cracks in the ceiling below then remove some of the weight, but I think you will not have to worry one bit! |

Shaggy dog, like has been said, depends on the joists, really. We lived in a 1930s house in 1985. I took the chimney out of our bedroom and tied new joists into the existing ones. Ten years later we bought a water bed, a king size one. It sat directly on top of my tied in joists. I did wonder! However, the plaster boarded ceiling below didn't even show a hairline crack when we left in 2006. Personally, I wouldn't worry unless you were storing old bank safes! Now left.

Jolly Good
That will put my fears at rest then. Will keep an eye on the dining room ceiling and see how it looks. Floors not making any creaking noises so will just keep an eye on it and see how it goes. Still have both chimneys below and in my room so all should be nice and strong. So far just need another shed, and a workshop extension and the rest will fit |
