This gazebo took 2.5 hours to put together with two people.  The main canopy was difficult to put on but after stretching the fabric, it seemed fine.  A couple of the metal poles had boogered up ends but we just used a screwdriver to bend the openings.  You don't need to put either awning up if you don't want to.  This was one of my questions which no one seemed able to answer.  We put up one.  It rained later that night.  Be warned that water does not pool on the main canopy but does on the awning if you leave it up.  I came home from work and the poles connecting the awning arms were bent badly.  I will now put the awning down when not in use.  Note that when the awning is down, the wind will blow it as nothing is holding it down.  I put mine on a deck so I use bungees to keep it down which work well.  Finally, it's more like 10x10, if that.  Overall I am pleased with this gazebo.
