Key Takeaways
• When designing accessibility solutions for rises above 1 metre, architects face a choice between fully automatic barrier systems and more cost-efficient manual options.
• The call explored how the Westminster, Mayfair and Big Ben Electric Stairs systems suit different rises, pit depths and stair configurations.
• Manual removable barriers can offer meaningful cost reductions for projects where staff-assisted operation is acceptable.
• Space behind the upper staircase, pit depth requirements and stair width are critical design factors in early planning.
• Hidden lifts are always bespoke and built to match the architecture, which is why early technical guidance is essential.
Introduction
When designing hidden accessibility solutions for rises above 1 metre in hotels, heritage buildings and high-traffic entrances, architects often face a complex challenge: how to balance regulatory enclosure requirements, space constraints and project budgets. The discussion behind this article explored these issues in detail, examining why different Sesame Access solutions were suitable or unsuitable based on rise height, pit depth, available space and client expectations. This article explains the reasoning behind those recommendations and offers practical insights that apply to most staircase-integrated lift projects.
What Lift Options Were Evaluated?
The architect required a hidden lift embedded within a new staircase. Because the rise exceeded 1 metre, the solution needed protective barriers to fully enclose the user during travel. This led to an evaluation of several Sesame Access systems:
• The Westminster Equality Act Lift – a premium hidden lift with fully automatic rising barriers
• The Mayfair Stairlift – a compact alternative suitable for lower rises, or for higher rises when combined with manual removable barriers
• The Big Ben Electric Stairs – an electric retracting-stairs system offering tighter spatial control when space behind the staircase is restricted
Each option supports high-quality architectural integration, but the correct choice depends on rise height, pit depth and operational preferences.
Why the Westminster System Was the Primary Recommendation
The Westminster system became the lead option because it is purpose-built for rises above 1 metre, where enclosure requirements are strict. Its automatic rising barriers deliver a seamless user experience and minimise staff involvement. The system hides beneath retracting stair treads, making it ideal for entrance lobbies that must remain visually clean.
This product is typically selected when clients prioritise automation, architectural finish quality and minimal operational steps for staff.
Why the Mayfair System Was Also Considered
The Mayfair system normally serves rises under 1 metre because it uses a compact platform design. However, during the discussion it also became relevant for higher-rise applications when configured with manual removable barriers.
This makes the Mayfair a strong choice when:
• the design team wants a simpler mechanism
• the client has a lower budget
• staff-assisted operation is acceptable
• the project does not require automatic barriers
This flexibility allows the Mayfair configuration to serve a wider range of projects than its core use case might suggest.
How Big Ben Electric Stairs Fit Into the Design Discussion
The Big Ben Electric Stairs option was referenced because certain staircase layouts benefit from electric-powered stair retraction rather than hydraulic systems. Electric stairs can reduce the length of space needed behind the upper riser, which is useful in tight lobbies or where back-of-house structure limits recess depth.
While electric systems generally increase project cost and complexity, they provide enhanced spatial efficiency and more precise movement control.
How Manual Removable Barriers Reduce Cost
A key theme in the conversation was how manual removable barriers offer a more affordable route to full compliance. Instead of automatic rising barriers built into the platform, the system uses removable side and front barriers that staff clip into place as needed.
This provides cost benefits because:
• the mechanisms are simpler
• fewer moving components are required
• pit depths can sometimes be reduced
• fabrication and installation are less complex
For many clients, especially those with occasional wheelchair use or staffed reception areas, this solution is both practical and cost-effective.

Typical Cost Considerations Without Using Actual Figures
Although exact numbers cannot be shared here, the relative pricing differences discussed in the transcript can be summarised as follows:
• Westminster systems with automatic barriers fall into the premium category because of their advanced safety mechanisms and deeper pit requirements.
• Mayfair systems with manual removable barriers sit in a more affordable category due to the simpler operation sequence.
• Electric retracting-stair variants generally fall into a higher-cost category compared with their hydraulic counterparts.
This structure gives design teams a clear, relative understanding of how different product families compare without referencing specific figures.
Key Spatial Requirements Raised in the Discussion
Architects reviewing hidden lift integration should consider:
• stair width (typically around 1250 mm minimum for Westminster moving stair assemblies)
• space behind the upper riser to store the treads when retracted
• pit depth for barrier mechanisms
• landing handrails to protect the opened stair void
• the number and height of risers
These factors determine which model is feasible and whether electric or hydraulic stair systems are preferable.
Frequently Asked Questions (FAQ)
Which lift is best for rises above 1 metre?
The Westminster system is generally recommended because it provides full automatic enclosure as required by regulations.
Which lift is best for projects with tight budgets?
The Mayfair system with manual removable barriers is a strong option for cost-sensitive projects.
Can hidden lifts be used in existing buildings?
Yes. All Sesame lifts are bespoke and can be engineered to suit heritage projects, hotels, offices and public buildings.
Do I need a pit?
Yes. All systems requiring enclosure must have a pit for the mechanism. Depth varies by model.
How do manual barriers work?
They are inserted by staff before each use. This is simple to operate and is common when full automation is not required.
