Both these sheds incorporate timber framing and hybrid framing elements. The floors are traditionally timber framed without the use of metal fasteners, which tend to rust quickly under such humid conditions as the underside of a shed. The shed at left has a split level floor to follow the contour of the slope it sits on. Most sheds can be set on floating foundations as these are. This method when properly executed on well drained soils provides an economical and reliable foundation. The wall and roof framing are a mix of stick framing and timber framing techniques. All wall and roof sections have inlaid cross bracing. Cross ties , rafters, and wall plates interlock and /or overlap so that wood members carry the loads not nails. The strength of these buildings comes from the framing not the sheathing.
