This arrives with 2 large boxes of parts
The instructions are good and everything is well labeled.
It is quite the building project. You will definitely need tools (like a drill, a couple size screwdrivers: plywood and a circular saw if you want a floor in it)
You will definitely need two people to assemble, one to hold things together as the other installs stews/ it isn’t a one person assembly.
The screws in the ramp were tiny, it arrived broken (screws pulled out/ not broken wood) and trying to put them back in they continued to fall out. We used other screws. They just aren’t big enough to hold.
But all said… you get a lot of supplies for a modest price. In the end it looks good and it is a good value.
Just know that this isn’t a simple pop together project. It needs a whole day, 2 people and at least one of those people needs to be handy with and own a variety of tools.
Ours also took a bit of extra time as we adapted it to fit a catio door from a window.
