There are various reasons why windows on the sides of homes are not installed: 1.-Most city construction rules mandate that each open living room have one operable window. According to this logic, an architect would position a window where there is a better view, such as at the front or rear, rather than on the sides. However, this rule was written before energy efficiency became an issue, so it is possible that there is another reason why the law requires one window in the living room. 2.-Side windows are viewed as less important than the main entrance and other large windows. This is probably because they are smaller and allow more heat to escape from inside the home. Also, people usually notice side windows more readily, which may discourage people from breaking them. 3.-The main reason why windows on the sides of houses are not installed is because architects do not want to be perceived as "cottage builders". They would rather use larger windows, which give a more spacious feeling to the house. Additionally, having no windows on the side of the house makes the interior design look more modern and/or contemporary.
