Yes, it is large and takes up some space, but the baby needs it. An adult human fits in the large, to give you some idea of size. Putting it together was not difficult. Please wear gloves or you might get a blister on your palm - yes, it is healing. Overall this new centerpiece of my living room looks good and it is exactly what we needed. 
Other reviews mention having your dog crate trained before buying one like this. I TOTALLY AGREE. 1st you would never want to put a little puppy into something big like this; be smart and work your way up. Even the largest Dane needs a small, medium, and large crate at points in life. I did need to make curtains for the sides as my baby has been using flight crates up to this point; it gives him a little more 'safety' feelings. Now to bring this point home, this is not a crate you can tear apart quickly and take outside for a  hose down.   Make sure you and your dog is ready for this crate.
