vertiwalk vertical walking


an initiative by ROMBOUT Frieling lab


The price of urban land is skyrocketing. And another 3 billion people are expected to live in cities: we will be forced to exploit vertical space: More and taller towers, the use of attics and roofs: we need to get up high.


Yet, our populations are ageing and staircases become major bottlenecks, while being unattractive at greater heights for all . Lifts are rarely a good alternative as they rely on significant external power, they deprive us from daily exercise and are expensive and intrusive to install.


Vertical Walking is a new proposal to move ourselves between floors in a building. Exploiting the potential of the human body and materials, significantly less effort is required, compared to taking stairs. No external energy is needed. This prototype has been succesfully tested by a wide range of users, including MS suffering Angelica, Nigerian amputee Abiodun as well as young office tower workers who found it ‘incredibly cool’.


It is the ambition to develop this experimental prototype into solutions that can help them, and all of us, to move harmoniously through our vertical habitats of the future.

“A very refreshing innovation.

It caught our attention immediately.“


Johannes de Jong, former Chief Technology Officer, KONE



“This keeps people moving yet it can accommodate less able people and it requires no power at all!

What more do we need?“


Professor Alison McGregor

chair, biodynamics group, Imperial College London


“In the next 30 years we are going to have 3 billion new urban settlers.“


Dr. Joan Clos, Executive Director of UN-Habitat
