A nice precast concrete building in the Netherlands

I don't know for sure what's Holland's excuse to use that much of precast elements in the construction, but at least in Finland the top three reasons have been the unfavorable weather, high labor costs and migration from countryside to cities in the 60's.
In the beginning of the 60's the population of the capital area was a bit above 500 000, and by the end of 60's it was nearly 700 000. I may be exaggerating a bit, but still, the population increased by one third during a decade! So they needed to build. A lot. Fast. In the construction boom of the late 60's and early 70's some of the concrete block houses were designed to last for 30 years only. They were not designed to go through the putkiremontti, they were not designed to go through the facade renovation - which makes the renovation really expensive today, and even after the renovation end result may not fulfill the requirements of the 21st century.
So, what shall we do with Merihaka? Any concrete suggestions?
