Internal ceiling height

The ceiling height inside the existing garage was looking a bit low, more so because of the required floor insulation etc. I employed a structural engineer to do calculations and drawings for altering the 22 existing roof trusses to allow another 30cm ceiling height. This all worked out well (although time consuming) All the roof trusses had to be cut, legs strengthened, and the lower truss beams bolted up to the new level. Dawn cut all the studding (ohhh my nails !! ) for the bolts while I cut and assembled the trusses. Worth it in the end though !!
This picture shows the strengthening legs and bolts etc.
