Understand which dimensions you are comparing
A brochure may show several measurements. They describe different parts of the installation:
- Cabin or platform size: the usable space inside the lift.
- External or shaft dimensions: the overall space occupied by the specified lift arrangement.
- Structural opening: the opening required through a floor or within the building.
- Clear door opening: the usable entrance width.
- Pit and overhead requirements: the space required below the lowest landing and above the upper landing.
These measurements are not interchangeable. Manufacturer drawings distinguish between platform size, shaft size, door opening and floor opening, so a brochure’s headline size should never become the builder’s setting-out instruction. Aritco’s technical drawings and product downloads illustrate these distinctions; use the current drawings for the model being proposed.
Start with the people using the lift
Before choosing a compact model, describe the intended use. Will the lift mainly carry one person, accompany a family member or accommodate a particular mobility aid?
If wheelchair access is part of the brief, share the actual chair dimensions and discuss entry, exit, accompanying assistance and the approach to each door. A cabin measurement alone does not establish whether the complete route will work.
Think about future use too. A layout that works for the household today may feel restrictive if needs change.
Check every landing
A lift may fit within a floor plan while creating an awkward arrival space upstairs. Review the relationship between each entrance and nearby bedroom doors, corridors, stairs and furniture.
Check how people approach the lift and where they stand while waiting. Different door arrangements can change both the lift specification and the surrounding layout.
Confirm the model before construction
The practical sequence is to assess the location, shortlist suitable models and obtain coordinated supplier drawings before finalising structural openings and finishes.
For an existing villa, bring available architectural drawings and photographs to the first discussion. The home lift site survey checklist explains what to prepare. Your selected supplier and relevant project professionals should confirm the final dimensions and feasibility for the property.
Common questions
Can a lift fit beside an existing staircase?
Possibly, but staircase geometry, structure, landing access and the selected lift requirements need to be assessed together.
Is there one standard home lift size?
No. Usable space, external dimensions, door configuration and building requirements vary by model. Request a current model-specific drawing before planning construction.
