My 16 year old son and I assembled the 8 x 10 over the course of a few days.  Did pre-assembling of trusses, gables and doors in our garage.  Then moved everything outdoors to the concrete pad, put down the floor, then the walls.  The first wall corner was stubborn, but after that the remaining walls snapped in place.  Added the trusses, roof panels and sky light the next day.  Everything was well engineered and went together just like the instructions stated.  Doors close and latch well.  Fits my snow blower, push mower, wheel barrow, shovels, extra shelving, etc., etc.  And no more having to repaint or re-shingle an old wood shed!  Very pleased with my Lifetime shed.
