I am building a 2 storey 10x5m agricultural shed with general purpose storage room/office over.
It is built with 100mm concrete blocks (dense outer/Durox inner) with 100mm empty cavity (3 sides) and 150mm Durox/wood clad on other.
I have a question relating to eaves details and roof design, which will be pre-fabricated raised tie trusses, half hip ends and ultimately covered with slate.
Can I support the trusses on the outer leaf ? Why are they normally on the inner leaf ?
Should I close the open cavity, if so how - block on flat or just leave open ?
What size wall plate should I use (trussed rafters are 9x2 at 400 centres due to very high collar to increase ceiling height) and should joints be lapped ?
Any advice much appreciated.
