Ceiling Heights
Ceiling height is measured internally from finished floor level to finished ceiling level. The height of a ceiling contributes to amenity within an apartment and the perception of space. Well designed and appropriately defined ceilings can create spatial interest and hierarchy in apartments.
Ceiling height is directly linked to achieving sufficient natural ventilation and daylight access to habitable rooms. The ground and first floor levels of mixed use apartment buildings should have increased ceiling heights to ensure their longer term adaptability for other uses.
Greater than minimum ceiling heights for retail and commercial floors of mixed use developments are encouraged to promote flexibility of use. Cafe and restaurant uses need greater minimum ceiling heights of 4m to allow for additional servicing needs
Ceiling height achieves sufficient natural ventilation and daylight access.
Design criteria
1. Measured from finished floor level to finished ceiling level, minimum ceiling heights are:
These minimums do not preclude higher ceilings if desired.
Design Guidance
Ceiling height can accommodate use of ceiling fans for cooling and heat distribution
Ceiling heights of minimum 2.7m help to achieve good daylight access and natural ventilation to residential apartments
Ground floors often need to accommodate a range of uses such as retail, cafes and restaurants, and should provide increased ceiling heights to allow for maximum flexibility of use
Ceiling heights contribute to the flexibility of building use over the life of the building.
Design Guidance
A number of the following design solutions can be used:
• the hierarchy of rooms in an apartment is defined using changes in ceiling heights and alternatives such as raked or curved ceilings, or double height spaces
• well proportioned rooms are provided, for example, smaller rooms feel larger and more spacious with higher ceilings
• ceiling heights are maximised in habitable rooms by ensuring that bulkheads do not intrude. The stacking of service rooms from floor to floor and coordination of bulkhead location above non-habitable areas, such as robes or storage, can assist.
Differing ceiling heights are an opportunity to provide visual interest in the building facade
Service bulkheads are wholly contained within non-habitable rooms and do not intrude into habitable spaces
Design Guidance
Ceiling heights of lower level apartments in centres should be greater than the minimum required by the design criteria allowing flexibility and conversion to non-residential uses.
