Building plan for duplex

A duplex is a building that contains two dwellings, either two apartments or one apartment and a smaller private residence, often on two separate floors. The term “duplex” is used in North America, South America (especially in Brazil), Western Europe, Australia and New Zealand. Although the terms are not synonymous, a building with one unit per floor is typically called a “twin home”, while a building containing two units per floor is called a “two-flat”. In Australia and New Zealand, duplexes are often built as part of medium-density apartment blocks.

A duplex house plan is a type of residential house plan that has 2 units on one level. Each unit can be either an apartment or a house. A duplex house plan will have 2 master suites (1 in each unit). It will also have 2 kitchens, 2 living rooms and 2 garages (1 in each unit).

Duplex floor plans are usually designed for low cost housing but can also be used for luxury homes.


A duplex is a type of building that has two units, side by side. The units are often two-story, but they can be one story as well. In a duplex, each unit has its own entrance and can be accessed through its own front door.

Duplexes are becoming more popular in the U.S., especially in cities where space is at a premium and housing prices are high. They offer an affordable means of living in areas where real estate is expensive.

A duplex can be built as small as 1,000 square feet (93 square meters) or as large as 10,000 square feet (929 square meters). Typically, a one-story duplex will have 2 bedrooms and 1 bath on each floor; a two-story duplex may have 3 bedrooms and 2 baths on each floor or 4 bedrooms and 2 baths on each floor.

The most common layout for a duplex is to have both units facing the street so that they have street access from the front yard; however, it’s also possible to only have one unit facing the street with the other unit facing an alleyway or another property line.

A duplex is a building that contains two separate units. Each unit has its own entrance, and both units are attached to the same set of walls. There are many different types of duplexes, but they all have the same basic layout. Duplexes can be single-family homes or townhouses that are built side-by-side and share the same foundation. The most common form of duplex is a townhouse with two separate units on one floor.

Types Of Duplexes:

Single-Unit Townhouses: A single-unit townhouse is a type of duplex where both units are located on the first floor or basement level. The front door of each unit leads directly into their own living room and kitchen area. There is no shared wall between them, and they each have their own private entrances from outside.

Two-Unit Townhouses: A two-unit townhouse has two separate floors with two separate entrances from outside. The bottom floor consists of one unit while the top floor consists of another unit (usually stacked on top).
