Common Disabled Access Ramp Design Mistakes and How to Avoid Them

Disabled access ramp design plays an important role in creating safe, practical and accessible entrances for people with disabilities and reduced mobility. Whether a ramp is being installed at a private home, school, healthcare facility or commercial building, careful planning is essential to ensure the finished system meets the needs of its users.

A disabled access ramp should do more than provide a sloping route between two levels. The gradient, width, landing space, surface materials and surrounding environment all influence how comfortably and safely people can use it. Poor design decisions can create new accessibility barriers, even when the intention is to improve access.

At PARS Ramps, we specialise in bespoke modular access systems designed around individual buildings and accessibility requirements. In this guide, we explore ten common disabled access ramp design mistakes, explain why they matter and outline how they can be avoided.

Why Is Disabled Access Ramp Design Important?

Effective disabled access ramp design helps create environments that are easier to navigate for wheelchair users, mobility scooter users and people who experience difficulties with walking, balance or movement.

A properly designed ramp can support greater independence, reduce unnecessary physical barriers and improve everyday access to buildings. However, a ramp that works well for one user may not necessarily meet the needs of everyone who uses the entrance.

For example, a gradient that is manageable for a powered wheelchair user may be challenging for someone using a manual wheelchair. Similarly, a narrow ramp may accommodate one mobility aid but provide insufficient space for another.

Good ramp design must therefore consider the intended users alongside the building’s layout, available space and relevant accessibility guidance.

It is also important to assess the complete access route, including the approach to the ramp, entrance platforms, doorways and surrounding pathways. Even a well-constructed ramp can be difficult to use if other parts of the route remain inaccessible.

Mistake 1: Choosing a Ramp Gradient That Is Too Steep

One of the most common disabled access ramp design mistakes is selecting a gradient that is too steep for the intended users.

Ramp gradient describes the relationship between the vertical height being overcome and the horizontal distance of the ramp. A steeper gradient requires users to travel a greater height over a shorter distance.

While a shorter ramp may appear more convenient where space is limited, an excessively steep slope can make access difficult for manual wheelchair users, people using walking aids and those with reduced strength or balance.

Steep ramps can also create difficulties when travelling downhill, particularly where users need to control their speed or stop safely.

How to Avoid Incorrect Ramp Gradients

The first step is to measure the entrance height accurately and assess the available space around the building.

A suitable gradient should then be established based on the intended users and relevant building guidance.

Where a direct ramp would be too steep, longer ramp sections or changes in direction may help create a more manageable route. Intermediate landings may also be necessary depending on the overall design.

In England, Approved Document M provides relevant accessibility guidance, although the applicable requirements vary according to the building type and proposed works.

At PARS Ramps, our site surveys allow us to assess entrance heights, available space and accessibility requirements before developing a bespoke modular ramp configuration.

Mistake 2: Not Providing Enough Landing Space

Landing space is an essential part of disabled access ramp design, yet it is sometimes overlooked when planning a new installation.

Level landings provide areas where users can pause, approach doorways, change direction and manoeuvre safely.

Without sufficient landing space, wheelchair users may struggle to position themselves correctly before opening a door or turning onto another ramp section.

A ramp that ends directly against a doorway without an appropriate level platform can be particularly difficult to use.

The problem becomes more significant where doors open towards the ramp or where users need additional space to operate the entrance.

How to Design Suitable Ramp Landings

Landing areas should be incorporated into the initial ramp design rather than added after the main ramp sections have been planned.

Appropriate level platforms may be required at the top and bottom of the ramp, at changes in direction and at other points identified by the relevant guidance.

The dimensions should account for the intended users, doorway arrangement and building requirements.

Modular access systems can incorporate bespoke entrance platforms and turning areas, helping create a more practical route between the ramp and the building.

Mistake 3: Installing a Disabled Access Ramp That Is Too Narrow

A ramp that is too narrow can restrict access and make everyday movement uncomfortable or difficult.

Different wheelchair models, mobility scooters and walking aids have different dimensions, meaning a ramp should not be designed around assumptions about the size of a standard wheelchair.

Additional space may also be necessary where users require assistance or where the ramp serves a busy public entrance.

Handrails and edge protection can further influence the available clear width if they are not considered during the design stage.

How to Choose the Correct Ramp Width

The appropriate width depends on the building, intended users, frequency of use and applicable accessibility requirements.

A residential ramp serving one household may have different design considerations from a ramp at a school, hospital or public building.

It is important to assess the clear usable width rather than simply measuring the overall structure.

PARS Ramps designs bespoke modular systems with different widths and configurations to accommodate individual project requirements.

By considering width early in the design process, it is possible to avoid unnecessary restrictions and create a more practical access route.

Mistake 4: Overlooking Slip Resistance and Surface Conditions

The surface of a disabled access ramp plays an important role in its everyday usability and safety.

Outdoor ramps are exposed to rain, frost, dirt and changing weather conditions throughout the year. If unsuitable materials are used, the surface may become slippery or difficult to navigate.

Smooth finishes, poor drainage and accumulated debris can increase the risk of slipping, particularly for people using walking aids or those who experience difficulties with balance.

Surface condition can also deteriorate over time if the ramp is not maintained appropriately.

How to Improve Ramp Surface Safety

Choosing a suitable slip-resistant surface is an important part of disabled access ramp design.

Materials should be appropriate for the intended environment and expected level of use.

Drainage should also be considered to help prevent unnecessary water accumulation, while regular cleaning and inspection can help maintain the condition of the surface.

For external installations, durable materials designed for changing weather conditions can provide practical long-term benefits.

Although no surface can eliminate every risk in all conditions, appropriate material selection and maintenance can help create a safer access route.

Mistake 5: Not Allowing Enough Turning Space

Turning space is particularly important where a disabled access ramp cannot follow a straight route.

Properties with limited outdoor space may require L-shaped or switchback configurations to accommodate the necessary ramp length.

However, introducing turns without providing suitable manoeuvring areas can make the system difficult to use.

Wheelchair users may struggle to change direction, while larger powered wheelchairs and mobility scooters may require additional space to complete a turn.

Poorly positioned handrails, boundary walls and other obstacles can make restricted turning areas even more challenging.

How to Avoid Restricted Turning Areas

Turning requirements should be considered during the initial site survey and design process.

The dimensions of platforms should account for the intended users and relevant accessibility guidance.

Where space is restricted, bespoke modular configurations can help make better use of the available area.

L-shaped and switchback ramps can provide practical alternatives to straight systems, provided the turning platforms are appropriately designed.

At PARS Ramps, our modular approach allows us to develop different configurations around the building and surrounding environment.

Mistake 6: Designing the Ramp Without Considering the Building Entrance

A disabled access ramp may be correctly designed but still fail to provide practical access if the building entrance itself remains difficult to use.

Raised thresholds, narrow doorways, heavy doors and poorly positioned entrances can create significant barriers for people with reduced mobility.

For example, a wheelchair user may be able to reach the entrance using the ramp but struggle to open the door because there is insufficient space to manoeuvre.

Similarly, a raised threshold at the top of the ramp may prevent a genuinely step-free transition into the building.

How to Create an Accessible Entrance

The ramp and building entrance should be considered together as one complete access route.

A professional assessment should examine doorway dimensions, threshold height, door operation, entrance platforms and the surrounding approach.

The ramp should connect to the entrance in a way that supports practical movement without introducing additional obstacles.

Where necessary, improvements to the doorway or threshold may need to be considered alongside the ramp installation.

This is why PARS Ramps assesses the wider entrance environment during the initial site survey rather than focusing solely on the height difference.

Mistake 7: Ignoring Handrails and Edge Protection

Handrails and edge protection are important features in many disabled access ramp designs.

Handrails can provide additional support for people who experience difficulties with walking, balance or movement.

Edge protection helps define the ramp route and can reduce the risk of wheelchair wheels or mobility aids leaving the surface.

However, these features must be incorporated appropriately.

Poorly positioned handrails can reduce the available width or interfere with manoeuvring, while unsuitable edge details may create additional obstacles.

How to Incorporate Appropriate Safety Features

Handrails and edge protection should be considered during the initial design rather than added as an afterthought.

The appropriate arrangement depends on the building, intended users, ramp configuration and relevant accessibility requirements.

Handrail positioning, continuity and usability should be assessed alongside the ramp gradient, width and landing areas.

A bespoke modular system allows these features to be incorporated into the overall design, helping create a practical and coordinated access solution.

Mistake 8: Failing to Consider Ground Conditions and Drainage

Ground conditions can significantly influence the design and installation of a disabled access ramp.

Uneven surfaces, sloping ground, poor drainage and existing landscaping can all create challenges.

If the supporting ground is unsuitable or the ramp is not properly installed, the long-term performance of the system may be affected.

Standing water can also create difficulties around entrances and access routes, particularly during colder weather.

Ignoring these conditions during the planning stage may result in additional work or an unsuitable finished installation.

How to Plan for Uneven Ground

A professional site survey should assess the existing ground levels, surface conditions and drainage arrangements.

The proposed ramp design should account for any significant changes in level and the requirements of the supporting structure.

Adjustable modular supports can help accommodate uneven ground without necessarily requiring extensive permanent groundwork.

However, suitable foundations and installation methods remain essential.

At PARS Ramps, we assess individual site conditions before recommending a modular configuration, helping ensure the proposed system is appropriate for the location.

Mistake 9: Choosing a Ramp That Cannot Adapt to Future Needs

Accessibility requirements can change over time, particularly in environments where buildings are regularly adapted or extended.

Schools may introduce additional modular classrooms, healthcare facilities may expand, and private households may experience changing mobility requirements.

A ramp that cannot be modified may become unsuitable if an entrance is relocated or the surrounding layout changes.

Traditional permanent structures can be difficult to alter once installed, potentially requiring extensive reconstruction.

Why Modular Disabled Access Ramp Design Offers Flexibility

Modular access systems provide an adaptable alternative to some traditional ramp structures.

Depending on the configuration and condition of the components, modular ramps can often be extended, adjusted, reconfigured or relocated.

This flexibility can be particularly useful for schools, healthcare facilities, temporary buildings and residential properties.

For example, an existing modular ramp may be adapted to accommodate a revised entrance layout or additional platform.

Any proposed alteration should be professionally assessed to confirm that the revised system remains suitable for the intended users and applicable requirements.

Mistake 10: Overlooking Accessibility Regulations and Design Guidance

One of the most important disabled access ramp design mistakes is failing to consider the relevant accessibility requirements before planning an installation.

Ramp design should not be based solely on appearance, available space or assumptions about standard dimensions.

Different buildings and projects may be subject to different requirements, making it important to identify the applicable guidance from the beginning.

Equality Act 2010

The Equality Act 2010 establishes duties relating to disability and reasonable adjustments in relevant circumstances.

Businesses, service providers, employers and other organisations may need to consider changes that help remove physical barriers for disabled people.

An access ramp can form part of these improvements, although the wider accessibility requirements must also be considered.

Building Regulations Approved Document M

In England, Approved Document M provides guidance relating to access to and use of buildings.

Different provisions apply to dwellings and buildings other than dwellings.

The appropriate requirements depend on the building type, proposed works and circumstances of the project.

BS 8300 Accessibility Guidance

BS 8300 provides guidance on designing accessible and inclusive built environments.

It can help inform the design of entrances, external routes, ramps and associated accessibility features.

How to Avoid Compliance Problems

Relevant regulations and guidance should be considered during the initial planning stage.

This includes assessing the building type, location, intended users and proposed installation.

Scotland, Wales and Northern Ireland have their own applicable building regulations and guidance, so requirements should not be assumed to be identical throughout the UK.

A ramp should never be considered automatically compliant simply because it has a particular gradient, width or handrail configuration.

The complete design must be assessed against the requirements relevant to the project.
