The stained bare ceilings doesn't win any points. I little sandblasting would help and still keep the loft look.
Sandblasting the ceiling would be a maintenance and health nightmare after occupancy as the concrete will continuously chalk/dust even more. Exposed interior concrete do dust a considerable amount even when left untouched.
I'm planning on washing and sealing my ceiling (with a very light transparent paint stain to even out the colour and imperfections), before I move into my new condo.
Carturo15: I also noticed the inconsistent window treatments when walking home, which are really noticeable on the lower floors. I believe window coverings were provided in River City 2, which I think is essential given how the windows and the white theme is so important on the design of that building.
