Ukrainian "mamady" in Lviv. How a shelter room is built, how much it costs, and whether there is demand for them.

Construction has begun in Lviv on a residential complex featuring apartments with individual shelter rooms – similar to Israeli "mamadas," but adapted to Ukrainian realities. Despite Ukrainian law requiring only the creation of civil defense shelters, not fortified rooms within apartments, the project is the first of its kind on this scale.
There have been no implemented examples of this format in Ukraine yet. But is it capable of taking root, given the lack of formed demand and the rising cost of construction?
LIGA.net asked Lviv-based developer VD Group, which is building the first residential complex with shelter rooms, the project architect Oleksandr Stolovyi from Archimatika, as well as experts Roman Gerasymchuk, head of City Development Solutions, and Serhiy Rasputny, CEO of Caspian Service, about how shelter rooms are designed, what structures they consist of, how much their construction costs, and whether this approach can change Ukrainians' perception of safe housing.
