I have a room, roughly 5 metre x 5 metre square.
The floor is 5m by 4m as it falls short of one wall as there is
(potential for) access to a basement.
There are only 2 joists, one at the edge of the floor and one approx 1.5m
in from this. These joist are 6x3 inch
The floor is quite solid, except for near the edge as this joist is quite
The floorboards are full length and about 2 inch thick.
So I could just replace the rotten joist, this would leave me with a nice
solid floor, especially as I am putting some stairs in to the currently
inaccessilble basement so could implement some sort of upright support.
Would you add extra joists?
There is only just enough height so if I could replace both joists with
more numerous but smaller joists it would be of benefit.
