The "coop" part of that looks suitable for food, water, and the nestbox.
But I don't think it has enough roost space for the chickens to sleep at night.
And when there is a day of bad weather, where do the chickens hang out to avoid it? That "coop" does not really have anywhere for chickens to spend time while they are awake, except the ground underneath. It is so close to the ground that the space underneath will be cramped for most standard-sized chickens, although it would not be as bad for bantams.
If you got a big covered dog run (maybe 10 feet square), and put that cute little coop inside, it would work in some climates. But for places with cold, snowy winters and places that get a lot of wind, you would need a much bigger space that is protected from the weather so the chickens can spend their days comfortably.
And as others have pointed out, predators are a serious consideration in most places, and that is probably not very sturdy. (It does have hardware cloth, which is much better than chicken wire, so it is better than some prefab setups.)
I don't know where you live, but that makes a big difference. Some examples:
--If you live on an island with no big predators, and with mild weather all of the year, the coop may be fine and just need a much bigger run (parts of Britain or Hawaii might qualify.)
--If you live somewhere warm or hot all year long, you would be better with a secure covered run, roosts & nests in the run, and no enclosed "coop" at all (can be appropriate in Florida and other southern parts of the US, and is commonly called an "open air coop.")
--But for places with several distinct seasons and normal predator pressure, the chickens will need a bigger run and also a bigger space to spend their days when the weather is bad.
