Historic porticos are often grand entrances that define a building’s character and could be said to be some of the most iconic features in architecture. But for many, step-free access was never part of the original design. For architects and property managers, the challenge is clear: how do you make a portico accessible without altering its heritage appearance?
At Sesame, we’ve worked on multiple portico projects where the solution wasn’t obvious, but with some technical problem-solving and found a solution that works for the building, the budget and the users.
The unique challenges of porticos
Porticos bring specific design constraints:
Limited structural depth beneath the entrance, restricting pit size
Strict heritage and planning rules, preventing visible alterations
Fire-exit considerations, especially if the staircase is part of an evacuation route
Narrow landings or insufficient turning space for platform lifts
Varied user profiles, from seated wheelchair users to ambulant standing users
Each portico is unique, which is why a detailed site survey is always the first step. This involves measuring dimensions, pit depth, and hidden structural elements.

The most popular solutions
Depending on the building’s geometry and aesthetic sensitivity, our invisible lift solutions work well in porticos:
Retracting stair systems: Lower or retract to create a level platform. When stowed, the original staircase remains intact, which is ideal for preserving façades.
Concealed platform lifts: Rise through the stair arrangement or adjacent well, staying invisible until activated. Perfect where access must serve both residents and visitors.
Choosing the right Sesame Lift for a portico
Different lift configurations suit different portico scenarios:
Lift | Ideal conditions | Notes |
Central retracting stair with platform access | Minimal aesthetic change; great for seated-user access | |
Rising barriers for standing users, full containment | Suits high-traffic or mixed-mobility entrances | |
Vertical retracting stairs interfacing with the platform | Works where pit depth exists but width is limited | |
Highly constrained sites with compact retracting stairs | Ideal for narrow porticos or minimal excavation |
Step-by-step evaluation for architects
Site survey - Measure dimensions, thresholds, and structural elements.
User profile - Determine whether seated, standing, or mixed mobility access is needed.
Heritage and planning constraints - Identify limits on external alterations.
Fire-exit requirements - Integrate interlocks, UPS backup, or barrier management if needed.
In some cases, a side-mounted lift may be used if the central stair cannot be altered, but this requires coordination with structural engineers.
FAQs About Portico Lifts
Can retractable stairs meet accessibility standards alone?
Yes, if they include 1100mm high barriers on the platform.
Will lifts like Buckingham or Wellington alter the portico's appearance?
No, they remain concealed when not in use.
Do platform lifts affect fire exits?
Potentially, early consultation with fire officers is essential.
What pit depth is needed?
Depends on the model (typically 210 mm-1,600 mm). A site-specific survey confirms feasibility.
Can these lifts be installed in listed buildings?
Yes, many listed buildings have successfully incorporated concealed lifts with conservation approval.
With careful planning, a structured evaluation, and the right lift solution, you can create inclusive, safe, and beautiful entrances that respect the building’s architectural heritage.
