There must be thousands of these up and down the country about which councils could do little, even if they knew about them.I know of a few properties that have loft bedrooms with stairs,lights,heating and vulux windows which are described as floored storage areas when sold
Potential buyers will look at a property and use the space in the loft as they see fit (ie just storage, or as a bedroom). Doesn't make it safe, though, and I wouldn't like to see a loft space used as a bedroom for kids, with no linked alarms and no protected escape route.
