Today, we'll discuss Universal Design, which is about creating environments that everyone can use comfortably and safely. Can anyone tell me why this is important?
It's important because not everyone has the same abilities. We need to make things accessible for everyone!
Yeah, like how people in wheelchairs need ramps.
Exactly! Universal Design aims to include everyone from the beginning of any project, so let's unpack the seven principles that guide us in achieving this.
Equitable Use and Flexibility in Use

Universal Design is the philosophy of creating environments usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. It emphasizes inclusion from the start of the project lifecycle.
Detailed Explanation
Universal Design is a concept that aims to make all environments accessible and usable for everyone, regardless of their physical or cognitive abilities. This approach suggests that from the very beginning of a project, designers and engineers should consider how to accommodate all potential users instead of making adjustments later for those with disabilities. It highlights the importance of inclusivity right from the planning stages.
Examples & Analogies
Imagine a playground designed for children of all abilities. Instead of just adding a few accessible swings after the playground is built, the playground is created with ramps, wide walkways, and sensory-friendly play equipment from the start, ensuring that every child can enjoy and access the space equally.
Equitable Use

Chapter Content
Design should be useful and marketable to people with diverse abilities. Example: Automatic doors that serve people using wheelchairs and people carrying luggage.
Detailed Explanation
The principle of equitable use states that designs should be beneficial for all users. This means creating spaces that do not favor one group over another and that everyone can use with ease. Automatic doors, for example, not only assist those with mobility challenges but are also convenient for those who have their hands full, making them a practical feature for all.
Examples & Analogies
Think of a busy airport where everyone is rushing to catch flights. Automatic doors are a common feature there. They help everyone, whether a person pushing a wheelchair or someone carrying heavy luggage, enter and exit without hassle.
Flexibility in Use
