It took about 1 hour, give or take, to assemble.  instructions were good.  It looks great on my front yard house wall.  It was tricky to figure out a way to mount the trellis on a stucco wall as they don't sell long enough stucco screws to pass through the thickness of the trellis and the spacer.  I ended up using liquid nails adhesive and different spacers.  Hope it holds!
