Just realized that I neglected to state that the tiny house I am building is designed to be "skid mounted" so that it can be tilt tray moveable and/or retro-fitted for towing.
The draw bar and axle arrangement are conceptual and remain in my head. We have friends who have a farm so at worst case the distance to be moved is about 15km away.
Now that the sub-frame is parallel, the next challenge is to pull it into "square". This was achieved by the use of ratchet straps and a large plasters square.
Dimensions where still checked by measuring "corner to corner", noting the measurements then measure the opposite "corners to corner".
Once square, metal floor joists were welded to the ends of the RHS.
In order to ensure that the structure was kept square, diagonal bracing was welded beneath the floor joists.

| Parallel RHS prior to welding in the end metal floor joists, one of which can be seen on top of the floor. |

| 50mm x 50mm galvanized RHS welded beneath the floor joists to provide rigidity to the whole structure. |

| Means of securing the cross bracing. |
 |
| Some of the floor joists had knots in the timber and appeared weak. In this case the weak section was strengthened by "doubling up" and securing with nails. |
