Although a true timber-frame was not in the budget for this job, we did work in a few mortise and tenon joints. This shed was built to serve a few different functions, foremost of which was to provide a nice surface for mounting solar panels. Working together with Northern Lights Energy http://www.nlightsenergy.com, we install solar electric, grid inter-tie systems. The other purpose for this shed was to house firewood, and a few pieces of lawn and garden equipment.
