fabrication des fermes,faitages et pannes

Last month we have been working in teams of 2 or 3 persons. Each team 1 ferme, 1 faitage, 2 contreventements and 2 pannes to fabricate. In total 6 fermes divided over 2 buildings.The faitage is the piece on the roof-ridge connecting the  (in this case 3) 'fermes'. The 'pannes' connect the 'fermes' as well, but they are in the middle (between faitage and wall). (Sorry for the french technical carpentry terms..)
