2. What is a duplex house? The term "duplex" refers to a single structure consisting of two separate dwelling units.  A semi-detached house or a duplex house is a single family dwelling house built as one of a pair that shares one common wall. Often , each house's layout is a mirror image of the other.

9. SOME EXAMPLES OF THE DIFFERENCES BETWEEN THE TWO UNITS OF A DUPLEX: In general , when designing a duplex the two units do not have to be the same in  the functions they offer ,  the size,  or  the external shape  and this gives many options in designing the duplex, 

10. SOME EXAMPLES OF THE DIFFERENCES  BETWEEN THE TWO UNITS OF A DUPLEX:  

11. One of the most special characteristics in a duplex design is the common wall (party wall)  . So what does it mean, why it is used, and how? The common wall or party wall:

12. A  party wall  (also known as  common wall ) is a dividing partition between two adjoining buildings that is shared by the occupants of each residence or business.  Very often the wall in this case is non-structural but designed to meet established criteria for sound and/or fire protection, i.e. a firewall . The common wall or party wall:

13. How thick does a party wall need to be? This type of wall is inherently thick and usually ranges from  250mm to 300mm . This means that by building the wall as a party wall, half of the thickness of the wall will sit on the adjoining owner's land

14. The best way to make this work is with : This leaves you free to use whatever Plumbing,   Electrical,   Insulation and    Finishes you want for the walls in each unit. 

15. Example of the functions around a separation wall :

16. More Economical : the apartments share an interior fire wall, economical to build than two separate homes of comparable size. More Efficient : Many of our plans feature mirror image living spaces, and this arrangement allows plumbing to be stacked along the shared interior wall, which is particularly efficient. Very suitable for regions that have high population .   Land Use : can be built two units on one land, so that save space.  Similar to Villa for luxury purposes. Advantages of Duplex House:

17. Neighborhoods problems : noise problems which make less privacy. Disadvantages:

18. Site Design in duplex house:

19. Lot Width and Depth  Access Standards  Parking  Standards  Open Space Standards Landscape Standards Things should be taken into consideration when designing a duplex:

20.  The minimum lot width shall be 50 feet and the maximum lot width shall  be 125 feet. The depth of the lot shall be a minimum of 100 feet. LOT WIDTH AND DEPTH

Access to second floor units shall be by a stair, which may be open or enclosed, but shall not face the street.   On a corner lot without access to an alley, parking and services shall be accessed from the side street.  Provide a covered area immediately outside the front door to each dwelling sufficient to provide protection from weather.   Entry should not be via any private outdoor living space. If the entry runs adjacent to a private outdoor living area, a suitable screening must be provided. 

22. Types of entrances:

23. Parking standares: For each dwelling in a duplex, space is provided for parking two vehicles on the lot and the space –  (i) for a single uncovered parking space- 4.9m by 2.6m wide; and  (ii) for a single covered parking space- 5m by 3m wide; and  (iii) for a double covered parking space 5 by 5.5m wide; and  (iv) for a single garage - 6m by 3m wide internally; and  (v) for a double garage - 6m by 5.7m wide internally.
