hi, we are about to buy a new house, the house has a detached double garage with large roof space and window.... my plan is to convert it into a games room with pool table... while it won’t have constant use, when it is used there may be several people up there along with a 6” pool table weighing around 80kg.
It is a new build, there are joists and a floor already installed but I’m sure the joists are too small for the project I have planned.
The room is 5.5 m long by 4.1 m wide, the existing joists run the 5.5 length and are sat on the breeze block wall. They are 600mm apart and 170mm x45mm....
Based on current regs I think I would need joists around 400mm apart and measuring 220x75....
As I don’t want to screw around too much, could I sister joists to the existing joists, this would mean joist sizes of 170x90 at a distance of around 550mm....
I’m open to sistering both sides meaning joists would be 170x135 at a distance of around 500mm...
Would this be OK? If not, how should I go about it without removing the existing joists?
Thanks in advance...
