This is the structural side of carpentry and is often considered to be the rough work before the final flourish of the second fix. Nonsense! In carpentry and joinery if you start right you finish right. Whether building stud walls, laying floor joists, or cutting rafters, if the work is straight and true then what follows will also be straight and true. Accuracy in these areas should be a primary concern for any tradesperson.
The stud walls shown in these images acted as party walls dividing two flats one from another. In this situation two walls are built on next to the other but not touching it, this separation cuts down on the transmision of sound through vibration. The finished walls are inulated and clad with two layers of plasterboard.
In this photograph the stud walls are built into a king post truss.
