Douglas Fir Platform

Okay so you're not going to see the boat house.  Last week ran away from me and now I'm on to the next project.  I'm currently working on a loading platform.  This is a douglas fir frame with a canvas "roof."  The canvas is only meant to cover the people below from the sun and rain and will be removed for the winter months.  The beams will be let into the columns but otherwise the members will be joined with bolts.
