Apartment Size and Layout
The layout of an apartment establishes the way rooms of different functions are arranged and located, the size of the rooms, the circulation between rooms and the degree of privacy for each room.
In addition, the layout directly impacts the quality of residential amenity by incorporating appropriate room shapes and window designs to deliver daylight and sunlight, natural ventilation, and acoustic and visual privacy. The apartment layout also includes private open space and conveniently located storage.
This living area has a combined kitchen dining area that opens directly onto the balcony
The layout of rooms within an apartment is functional, well organised and provides a high standard of amenity.
For open plan layouts, combining the living room, dining room and kitchen, the maximum room depth is 8 metres from a window
The depth of a single aspect apartment relative to the ceiling height directly influences the quality of natural ventilation and daylight access. The maximum depth of open plan layouts that combine living, dining and kitchen spaces is 8 metres
Apartment layouts are designed to accommodate a variety of household activities and needs.
Studio
Design Criteria
1. Apartments are required to have the following minimum internal areas:
The minimum internal areas include only one bathroom. Additional bathrooms increase the minimum internal area by 5m2 each.
A fourth bedroom and further additional bedrooms increase the minimum internal area by 12m2 each
2. Every habitable room must have a window in an external wall with a total minimum glass area of not less than 10% of the floor area of the room. Daylight and air may not be borrowed from other rooms.
Design Guidance
Kitchens should not be located as part of the main circulation space in larger apartments (such as hallway or entry space).
A window should be visible from any point in a habitable room.
Where minimum areas or room dimensions are not met apartments need to demonstrate that they are well designed and demonstrate the usability and functionality of the space with realistically scaled furniture layouts and circulation areas. These circumstances would be assessed on their merits.
1 Bedroom
Design criteria
1. Habitable room depths are limited to a maximum of 2.5 x the ceiling height.
2. In open plan layouts (where the living, dining and kitchen are combined) the maximum habitable room depth is 8m from a window.
Design Guidance
Greater than minimum ceiling heights can allow for proportional increases in room depth up to the permitted maximum depths.
All living areas and bedrooms should be located on the external face of the building.
Where possible:
Indicative layouts
• bathrooms and laundries should have an external openable window
• main living spaces should be oriented toward the primary outlook and aspect and away from noise sources
2 Bedroom
Design Criteria
1. Master bedrooms have a minimum area of 10m2 and other bedrooms 9m2 (excluding wardrobe space).
2. Bedrooms have a minimum dimension of 3m (excluding wardrobe space).
3. Living rooms or combined living/dining rooms have a minimum width of :
• 3.6m for studio and 1 bedroom apartments
• 4m for 2 and 3 bedroom apartments
4. The width of cross-over or cross-through apartments are at least 4m internally to avoid deep narrow apartment layouts.
Design Guidance
Access to bedrooms, bathrooms and laundries is separated from living areas minimising direct openings between living and service areas.
All bedrooms allow a minimum length of 1.5m for robes.
The main bedroom of an apartment or a studio apartment should be provided with a wardrobe of a minimum 1.8m long, 0.6m deep and 2.1m high.
Apartment layouts allow flexibility over time, design solutions may include:
• dimensions that facilitate a variety of furniture arrangements and removal
• spaces for a range of activities and privacy levels between different spaces within the apartment
• dual master apartments
• dual key apartments
Note: dual key apartments which are separate but on the same title are regarded as two sole occupancy units for the purposes of the Building Code of Australia and for calculating the mix of apartments
• room sizes and proportions or open plans (rectangular spaces (2:3) are more easily furnished than square spaces (1:1))
• efficient planning of circulation by stairs, corridors and through rooms to maximise the amount of usable floor space in rooms.
