houses in Vietnam have a quite peculiar shape.
the front, which faces the street, is only some few metres long while the length of the house is long usually 4 or 5 times the entrance.. floors are many.. why?
in Vietnam is easy to get any license to sell anything or to provide services, therefore almost every house has a little business at their first floor. because of this, the price for the part of the house which faces the street is high.. so there is almost never an entrance which is more than 4 metres wide (i’d say 3m is the average).. the rest of the house is cheap, and building floors in not so expensive too.. so as a result of all this: width is tight, length is long, floors are many.
