Question

what are the different between a single -storeyed and a multi-storeyed house?​

Answer 1

Answer:

Stacking that same square footage on multiple levels gives the home a smaller footprint and less roof area to construct and maintain.

Answer 2

Answer:

One of the most significant is that they allow for larger square footage than a single story home on the same lot. ... Two story homes also provide greater security and privacy. Because bedrooms are often on upper floors, they are more difficult to access by burglars and others with malevolent intent.
