Not every home lift needs to be installed inside a conventional lift shaft. Shaftless systems use their own supporting structure to travel between floors, providing an alternative to the traditional hoistway arrangement. For existing homes, this can reduce the need for extensive structural construction and make better use of available space.
The difference between shafted and shaftless lifts comes down largely to how the lift is supported and enclosed. A conventional lift operates within a dedicated hoistway, while a shaftless system incorporates its own supporting structure. The choice between the two depends on the lift design, property, available space and applicable building requirements.
What Is a Lift Shaft or Hoistway?
A lift shaft, also known as a hoistway, is the vertical enclosed space through which a conventional lift travels between floors.
A hoistway lift is installed within this dedicated vertical enclosure. Depending on the lift design and building, a traditional installation may involve structural walls, a floor pit, overhead clearance and dedicated equipment space.
For an existing home, creating a lift shaft can involve additional construction and may reduce usable floor area across multiple levels. However, not every residential lift requires a conventional shaft. The supporting structure and design of the lift determine how it can be incorporated into a building.
What Is a Shaftless Home Lift?
A shaftless home lift is designed to move between storeys through a trimmed ceiling aperture without any enclosing shaft walls.
-
Self-Supporting Structure: The lift carries its own load along twin structural rails anchored directly between the floor and ceiling, transferring forces into the building's floor plates rather than requiring load-bearing walls.
-
Minimal Disruption: Because it requires no dedicated hoistway, pit, or external machine room, it provides maximum layout flexibility for retrofitting into hallways, living rooms, bedroom corners, or stair voids.
For anyone researching a home elevator without a shaft, it is important to distinguish between “shaftless” and “construction-free”. A suitable opening between levels and appropriate structural preparation are still required.
The absence of a conventional shaft can provide greater flexibility when planning a lift within an existing home's layout, particularly where available floor space is limited.
How Does a Self-Supporting Home Lift Work?
The main difference between traditional and self-supporting home lift systems is how the lift is supported.
A conventional lift generally travels within a dedicated shaft incorporated into the building. A self-supporting system uses its own structural rails or framework to support and guide the lift.
With a self-supporting design, the structural elements form part of the lift system rather than relying on traditional load-bearing shaft walls. An appropriately sized opening between levels and suitable structural fixing points are still required.
This is an important distinction when comparing shaft and shaftless home lifts. Removing the need for a conventional shaft can reduce the amount of structural construction required, but it does not eliminate the need for proper site preparation.
Compact Home Lifts: Elegance and Elegance Plus
Compact Home Lifts offers two shaftless models designed around different space and accessibility requirements.
Compact Elegance
The Compact Elegance is designed for up to two passengers and has a footprint of less than 0.8 m². Its compact design can be suitable for homes where available floor space is limited.
The model uses a self-supporting dual-rail system, so a traditional lift shaft is not required. It can be installed in suitable areas of an existing home, subject to the property's layout and installation requirements.
Compact Elegance Plus
The Elegance Plus has a larger footprint of approximately 1.44 m² and is designed to accommodate a standard wheelchair or walking frame.
Like the Elegance, it uses a self-supporting dual-rail system without a traditional lift shaft. The additional internal space makes it an option where accessibility and passenger space are important considerations.
Both models demonstrate how shaftless home lifts can provide an alternative to conventional shafted systems where the property and installation conditions are suitable.
Lift Shaft vs Shaftless: What's the Difference?
The main difference is how the lift is incorporated into the building.
A traditional shafted system may require a dedicated enclosure and more substantial structural work. A shaftless system uses its own supporting structure and can therefore be considered for some retrofit applications.
When assessing residential lift dimensions in Australia, the lift footprint is only one part of the planning process. Floor-to-floor height, aperture dimensions, landing space, headroom and the surrounding structure also need to be considered.
For this reason, a compact lift does not automatically fit every location. The available space needs to be assessed alongside the technical requirements of the lift.
Can a Home Lift Be Installed Without a Shaft?
Yes. A home elevator without a shaft can be suitable for some existing homes, depending on the property and lift configuration.
Shaftless systems can be useful when installing a lift in an existing home. Potential locations may include hallways, corners, living areas, stair voids or other suitable spaces, depending on the home's layout.
This makes small home lifts in Australia worth considering where preserving usable floor space is important. A smaller footprint can provide more flexibility, although the overall installation still needs to meet the required structural and safety conditions.
However, “shaftless” does not mean “install anywhere”. Structural conditions, floor openings, travel path, ceiling height and landing requirements all need to be assessed before installation.
When Might a Lift Shaft or Enclosure Be Required?
A lift shaft requirement cannot be determined solely by counting the number of storeys. Under the National Construction Code (NCC), requirements for lift separation and enclosure can depend on the lift configuration, building classification, number of storeys connected, sprinkler protection and other building conditions.
Key considerations include:
-
Multiple storeys: The NCC contains specific provisions for lifts connecting more than two storeys. The requirements can vary depending on the type and classification of the building.
-
Fire separation: Where a lift passes through floors that are required to provide fire separation, additional enclosure and protection requirements may apply.
-
Sprinkler protection: Some NCC provisions provide different requirements or concessions for buildings protected by compliant automatic sprinkler systems.
-
Building classification: Requirements can differ between residential buildings and other building classifications, so the rules applying to one property should not automatically be applied to another.
-
Lift type and installation: The type of lift, its location and how it interacts with the building can also affect the applicable requirements.
For this reason, a three-storey property should not automatically be assumed to require a traditional lift shaft. Equally, a shaftless system should not be assumed to be suitable for every three-storey installation.
The applicable NCC provisions and relevant parts of AS 1735 should be checked for the specific building and lift configuration before installation.
What Should Be Considered Before Choosing a Shaftless Home Lift?
Before selecting a shaftless lift for an Australian home, assess the following site-specific factors:
-
Aperture & Headroom: Position and structural trimming of the ceiling opening, floor-to-floor heights, and overhead clearance on the upper level.
-
Residential Lift Dimensions: Comparing available floor space with the requirements of the selected lift. The Compact Elegance has a footprint of less than 0.8 m², while the Elegance Plus has a footprint of approximately 1.44 m² and is designed to accommodate a standard wheelchair or walking frame.
-
Location Feasibility: Ensuring the lower and upper landing spaces have unhindered pathways and safe ingress/egress.
-
Budget & Installation Scope: Considering residential lift prices in Australia, including installation, builder site preparation such as aperture cutting and joist trimming, and any structural work required for the chosen lift system.
-
Local Building Regulations: Confirming compliance with local council guidelines and NCC specifications for homes in metro areas like Sydney, Melbourne, and Brisbane.
Choosing Between Shafted and Shaftless Home Lifts
Do home lifts need a shaft? Not always. A shaftless home lift provides an alternative to a conventional lift by using a self-supporting structure rather than a traditional enclosed shaft.
Compact Home Lifts' Elegance and Elegance Plus models use a self-supporting dual-rail design and are designed without a traditional lift shaft. For homes considering a retrofit, the most suitable option depends on available space, structural conditions, accessibility requirements and the applicable Australian building requirements.
FAQs:
1. Can a home lift be installed in an existing home without a shaft?
Yes. Some self-supporting shaftless home lifts are designed to suit retrofit applications. Instead of building a conventional enclosed hoistway, the lift uses its own supporting structure. Installation may still require an appropriately sized floor opening, structural trimming and other site preparation depending on the property and lift system.
2. How many storeys can a shaftless home lift travel?
The number of storeys a shaftless home lift can connect depends on the specific lift system and its approved configuration. Requirements can also change as the number of levels increases. Under the National Construction Code (NCC), lifts connecting more than two storeys may be subject to additional separation and enclosure requirements depending on factors such as building classification and sprinkler protection. The applicable NCC provisions and relevant parts of AS 1735 should therefore be checked for the specific installation.
3. How much space do you need for a shaftless home lift in Australia?
The space required depends on the lift model and the property. The Compact Elegance has a footprint of less than 0.8 m², while the Elegance Plus has a footprint of approximately 1.44 m² and is designed to accommodate a standard wheelchair or walking frame. The required floor opening, landing space, headroom and surrounding structure also need to be considered during planning.
4. What building and preparation work is needed for a shaftless lift?
While a shaftless lift eliminates the need for a conventional structural shaft, it is not entirely “construction-free”. Depending on the property and lift system, installation may require cutting and structurally trimming the ceiling or floor opening, preparing suitable fixing points, checking overhead clearance and completing the required electrical work.
5. What happens if the power goes out while you are in a shaftless home lift?
What happens during a power outage depends on the lift model and its emergency features. Some residential lifts are equipped with battery backup or emergency lowering systems that allow occupants to exit safely if mains power is interrupted. The specific emergency operation should be confirmed with the lift manufacturer before installation.
