I agree with you, UrbanDev! Many of the standard level new buildings in the city have low quality finishing and little or no design merit. Some will stand the test of time, but in my opinion, many won't. Investors frequently buy what's bright and clean rather than what will have long term value. I know of several projects built around 4-5 years ago, which already look horrendous due to low quality building materials/poor design, etc.
However, as of now, there are too few reasonably-priced, problem-free, renovated classic apartments in perfect buildings, so locals frequently take the easier option of buying one of the former. It happens all over CEE as far as I can see, but particularly in Bp. Despite having one of the highest proportion of neo-classical/secessionist properties of any city in Europe, most of them are unfortunately in terrible condition.
