Duplex homes are also known as “Gemini” or “Twin house.” This is a design mainly adopted in densely populated areas like busy cities or in expensive waterfront properties.

This type of building design is when two units are built as a single dwelling. This is a single housing structure with two housing units sharing one wall. The wall divides the structure into two separate houses. Duplex can range in size, amenities and styles.

The duplex homes seem to be a single unit but have two distinct entries. This home building style is beneficial as it conserves space and also economical compared to spit units. They are intended to shelter more than one family. The houses have double insulated walls and separate garage space. Each house has its own garden, driveway, entry and other features of a freestanding house.
