When we started with kitchen refurbishment project at NBH (Nikolaiev Baby House) back in 2005, we had to let some parts down because of limited budget. Five years later, one of the room we forgot at that time was seriously suffering from humidity problem. Especially during cold season when window has to stay closed.

We then decided during last October visit that we have decided to exchange the window and get a proper ventilation system installed to finally solve that humidity issue in this room.

This “small” project came to a successful end right before winter came.
