When you really consider this type of conversion, it takes the pressure off having to build another 18 x 3 bedroom units. What a benevolent LL.They reckon property inspectors that are unbribable are just too expensive..
most people only need between 6&8 hours sleep per day. Worst case scenario is that you can have 3 rotating sleep shifts. Best use would be 4 light sleepers x 6 hours each.It's not unknown to have 'hot-bunking' where tenants take it in turns to sleep. Assuming an under-the-counter 12 hour/day job that can double capacity.
