The construction took three months to complete. In the end, only the windows were still missing. These are in short supply throughout Ukraine, says Stanislav Lutskovych, founder of the Ukrainian Friends Foundation. Lutskovych is a well-known Ukrainian businessperson, who has become an internationally recognized social entrepreneur during the war. According to him, it's Russia's eight month bombing campaign that is to blame for the critical shortage of windows. According to information from the UN, roughly 6.5 million Ukrainians have fled to other parts of the country, with the majority arriving in the west from the eastern and southern parts of Ukraine, which have seen heavy fighting. 3.2 million others have taken refuge in other countries.
