Today's class focuses on the dimensions of stairs as outlined in the NBC. Can anyone tell me what the minimum tread and maximum riser dimensions are?
I think the tread is 300 mm, but I’m not sure about the riser.
Correct! The tread should be at least 300 mm, and the riser must not exceed 150 mm. This ensures safety and ease of use. Remember this as T & R! Could anyone explain why these dimensions are crucial?
Larger treads make it easier for people to place their entire foot on the stair!
Exactly! It's about preventing slips and falls, especially for individuals with mobility issues. Let’s summarize: T & R represent Tread 300 mm and Riser 150 mm!
Let’s now talk about handrails on stairs. Which specifications must we remember?
They need to be continuous and at specific heights.
Absolutely! Handrails must be present on both sides of the stairs, at heights of 760 mm and 900 mm. This supports not only safety but also accessibility for everyone, right?
Yes! It helps people who need support while going up or down.
Great point! To help remember, you can think of 'H & H': Handrails at 760 mm and 900 mm.
Why do you all think the guidelines for stairs are particularly significant?
To ensure everyone can access them safely.
Exactly! The goal is universal access, which supports those with disabilities and the elderly. Remember, inclusive design means thinking beyond just regulations!
So, it's not only about legal requirements but also about empathy and usability.
Well said! Accessibility improves quality of life for everyone. Let’s summarize the importance of T & R plus H & H for both functionality and safety!
When you climb a stair, without a care, remember the tread, it's 300 instead!
Imagine a person with a cane climbing stairs. With treads of 300 mm and risers no higher than 150 mm, they feel safe and secure, making their way to the next floor.
Think of ‘H & H’ for Handrail heights: 760 and 900 mm to support us right!
T & R stand for Tread & Riser; remember T for 300 and R for 150, an excellent measure!

This section outlines the guidelines for stair construction to ensure accessibility as per the National Building Code of India.
The section covers critical requirements for stairs, including dimensions for treads and risers, specifications for handrails, and considerations for ensuring accessibility. These guidelines are vital for complying with accessibility standards and promoting inclusive design.
The guidelines for stair design under the National Building Code (NBC) 2016 focus on ensuring that stairways meet specific accessibility requirements crucial for inclusivity in building designs. Key guidelines include:
By adhering to these design standards, architects and builders can create environments that accommodate everyone's needs, reflecting the principles of universal design.
