150 square meters on average is about 450 square feet, which must be a palace in DPRK terms. And that means half the people live in spaces smaller than that. Probably a lot smaller.
1600 sq ft is a decent sized house, and pretty massive for an apartment. I doubt anyone in North Korea has much better than an empty refrigerator box for housing.
I like the picture of fresh fruit. It's really telling what they choose to include in their propaganda.
I mean, look at the stunning lack of restraining orders littering my apartment, ladies. LOOK! IT MEANS I'M COMPLETELY NORMAL AND NOT AN OBSESSIVE CREEP!
