Stockholm , The size is perfect, i'm thinking the same problem also! the DOOR FRAME!!!!
I'm from Hong Kong, there're three ikea stores here, but 2016 ikea catalog hasnt came out here yet, even the price now is HK$3490, (APPROX US$ 447) , that is not cheap. I'm not sure if i will buy one if the price go up later.
I think about the detolf too, same thing, dont want to separate the modulars, but i've seen people combine two detlof into a double size , it's just im not sure if i can do it on my own.
