as architect and builder of the duplex project above, designed
and built the attached dual
occupancy. In this project, the two units are mirror image of
each other with a party wall down the middle. Each unit of the
dual occupancy consists of 3 bedrooms, ensuite,
bathroom, lounge & dining, kitchen, laundry and double
garage. The construction of the duplex building is of concrete
slab, full brick
construction, timber roof trusses with concrete roof tiles.
The building was built on a small block in Sydney's eastern suburb and
the soil type was sand.
The external wall of the duplex development is of face brick. The
interior wall finish is cement sand render with paint finish.
Ceiling is flush plasterboard and flooring is tile in wet area and
carpet in living areas and bedrooms. There are large balconies on
front of the duplex building and large entertaining BBQ area on the
rear. The FSR was utilized fully. AAPAC
has helped the client to realize the full development potential of the
site on a tight budget and achieve the maximum value for the
Typical to duplex development, an on-site stormwater detention system
had to be installed as part of the Council's requirement for the duplex
development approval. Due to the flat ground condition, the
stormwater detention system was in the form of galvanised steel
pipe in the ground.

WHAT IS A DUPLEX
WHAT IS A DUPLEX?
Duplex is a term used in the market to refer to two attached dwellings
on the same block of land. The two dwellings in a duplex do not
need to be side by side and they do not need to be mirror reverse image
of each other, as shown
in the duplex example on this page. However, it is true that many
duplexes are of this type. This type of duplex design is popular
because the length of driveway is minimized and the site does not need
to be too deep. Sometimes the front of the duplex are designed to
appear as a single house.
The two dwellings in a duplex need to be attached but they can be
arranged in different way, eg. one on top of the other, one in front of
the other, or
one is single storey and the other is double storey.
Different duplex design should be considered to suit the site levels
& site profile and to maximize the good aspects inherent in a site.
The term duplex is not commonly used in most Councils' development
control guidelines. Instead, duplex development are usually
referred as dual occupancy development in Councils' documents.
This is because dual occupancy can be detached or attached. Attached dual occupancy is
referred as duplex in the market.
