As someone who lives in a 700 sq ft 1bd apartment, I guess maybe you could pack in another two bedrooms in with 300 more sq ft (my bedroom is ~ 120-130 sqft w ~ 25 sqft of closet space). You wouldn't have a whole lot of elbow room. Still makes more sense than the 2500+ sqft monstrosities we regularly build in the states.
Even 2500sqft is modest by modern American new build standards. It's pretty challenging to find a "nice" home that's <3,000 sqft in most markets, and basically impossible to find a truly high end home that's <4,000.
