Let's start with the importance of clear widths at door entrances. Why do you think it’s crucial for doorways to have a minimum width of 900 mm?
I think it’s because it needs to allow wheelchairs to pass through easily.
Exactly! This dimension ensures that individuals using wheelchairs or mobility aids can enter safely without complications. It aligns with accessibility standards.
What happens if the door is too narrow?
Great question! If the door is too narrow, individuals may find it difficult or even impossible to enter, effectively excluding them from the space.
So, wide doors help everyone, not just those with disabilities?
Absolutely! A wider door also benefits parents with strollers, individuals carrying heavy items, and much more.
Can we remember the 900 mm width using a simple phrase?
Sure! We can say: 'Nine hundred, make it friendly!' This way, we can remind ourselves of the importance of having this width for friendly access.
To summarize, maintaining a minimum clear width of **900 mm** is essential for accessibility, accommodating wheelchairs, and offering inclusive access for everyone.
Threshold Requirements

Now, let’s transition to discussing thresholds. Can anyone tell me the maximum height allowed for thresholds at entrances?
I believe it’s 13 mm.
Correct! The requirement mandates that thresholds should not exceed **13 mm** in height. Why do you think this is significant?
It helps prevent tripping hazards when entering or exiting.
Exactly! A beveled edge on a threshold helps provide a smooth transition, which is critical, especially for those using mobility devices.
What if a threshold is too high?
If a threshold is too high, it creates a barrier that can cause falls. This contradicts the principles of accessibility!
How can we remember the threshold height?
A good mnemonic could be 'Thirteen smooth for easy move!' It highlights both the height and the need for a smooth transition.
To recap, the maximum threshold height is **13 mm**, and it is essential to ensure a smooth transition into buildings, thereby enhancing safety and accessibility.

Quick Overview
Standard
The section emphasizes the importance of maintaining a minimum clear width of 900 mm for door entrances and specifies threshold requirements to facilitate smooth transitions for individuals with disabilities. These standards are critical for enhancing usability and ensuring adherence to accessibility guidelines.
Detailed
Clear Width and Threshold
In promoting accessibility within building design, establishing the correct clear width for door entrances and appropriate threshold specifications is crucial. This section stipulates that the minimum clear width of door entrances must be 900 mm. This dimension is essential to accommodate wheelchair clearance and ensure that individuals who utilize mobility devices can navigate effortlessly.
Additionally, thresholds at entrances should not exceed 13 mm in height and must be beveled to facilitate a seamless transition between outdoor and indoor environments. This minimizes tripping hazards and improves usability for individuals with limited mobility or those using assistive devices. Adhering to these specifications not only meets legal requirements under various accessibility standards but serves to enhance the independence and dignity of all users.

Chapter Content
• Minimum clear width of door entrance: 900 mm (to allow wheelchair clearance).
Detailed Explanation
The minimum clear width for door entrances must be 900 mm. This width ensures that most wheelchairs can pass through easily, providing accessibility for individuals who rely on these devices. When designing or evaluating doors, it’s important to measure the clear width from side to side, without obstructions, to ensure compliance with this standard.
Examples & Analogies
Imagine trying to move a large piece of furniture through a doorway. If the doorway is too narrow, you struggle to get it through, and it becomes frustrating. Similarly, if a door isn't wide enough for a wheelchair, it could hinder someone from entering or exiting a space safely.

• Thresholds must not exceed 13 mm in height and should be beveled for smooth transition.
Detailed Explanation
The height of any threshold (the raised lip at the bottom of the door) should be no more than 13 mm. Additionally, it must be beveled, which means it should have a sloped edge. This design is crucial because it helps prevent tripping hazards and enables individuals who use wheelchairs or mobility devices to pass over the threshold smoothly and safely.
Examples & Analogies
Think about riding a bike over a speed bump. If the bump is too high, it can cause a jolt and potentially throw you off balance. In a similar way, a high, sharp threshold can create obstacles for individuals in wheelchairs. A beveled threshold acts like a gentle ramp, allowing a smooth transition from one area to another.
Key Concepts
-
Minimum Clear Width: A door entrance must have a minimum clear width of 900 mm for accessibility.
-
Threshold Height: Thresholds must not exceed 13 mm in height and should be beveled for smooth transitions.
Examples & Applications
An entrance door measuring 900 mm in width allows a wheelchair user to enter without difficulty, complying with accessibility standards.
Using beveled thresholds not exceeding 13 mm prevents tripping and ensures that users can transition smoothly into and out of buildings.
