Sill board +45mm longer than base to get 600mm between all studs - good or bad?
Planning to build a holiday house - slab on grade with a wooden frame. The foundation dimensions are 12 x 6 m. I received a construction suggestion where the baseplate extends +22.5 mm on each side of the slab, to achieve 600 mm spacing between the studs. Is this a good idea? What is customary? It seems beneficial for attaching the panels on the inside, but how is the baseplate affected by hanging outside the slab? The facade will extend past it, but the baseplate will still be exposed, and not all the load will go "directly" down into the slab?
As soon as you are about to build something with corners, module measurements become a problem. It is a bad idea to let the baseplate protrude when you have already cast the slab. Everything you attach to the studs on the outside will protrude beyond the edge of the foundation. Corners always require an extra stud, and the exterior perimeter is always larger than the interior. However, if you don't have an extremely narrow baseplate, the load aspect doesn't matter much.
