Vacant NL rated as one of the Top-10 of Sexiest Models of All Time

The installation Vacant NL – RAAAF’s contribution to the Venice Architecture Biennale 2010 – is in great company in this piece on Architizer: Lebbeus Woods, Antonio Gaudi, Jorn Utzon, Tadao Ando, Yuraka Sone and Ludwig Mies van der Rohe amongst others.






New Enactive Art Installation: The End of Sitting

The End of Sitting is a large spatial installation at the crossroads of visual art, architecture, philosophy and empirical science.

In our society almost the entirety of our surroundings have been designed for sitting, while evidence from medical research suggests that too much sitting has adverse health effects. RAAAF [Rietveld Architecture-Art Affordances] and visual artist Barbara Visser have developed a concept wherein the chair and desk are no longer unquestionable starting points. Instead, the installation’s various affordances solicit visitors to explore different standing positions in an experimental work landscape.

The End of Sitting marks the beginning of an experimental trial phase, exploring the possibilities of radical change for the working environment. This project is a spatial follow-up of the recently released mute animation ‘Sitting Kills‘ by RAAAF | Barbara Visser, developed as a vision on the workspace of 2025, commissioned by the Chief Government Architect of the Netherlands. Moreover, the art installation is the visual component of Erik Rietveld’s philosophical research project titled ‘The Landscape of Affordances: Situating the Embodied Mind’; the installation visualizes the  philosophical notion of a Landscape of (Standing) Affordances.

The End of Sitting is a collaboration with Looiersgracht 60, a new space for art and science in Amsterdam. Gibsonian ecologicla psychologist Dr. Rob Withagen of the University of Groningen (Center for Human Movement Sciences / University Medical Center) has studied 1) how people use the landscape of standing affordances and 2) how the amount of movement and 3) productivity compare to working in a traditional open office setting. The experiment on the rock of standing affordances has been recorded with 4 camera’s. The subjects’ use of standing affordances and data on productivity are currently being analyzed by Dr. Withagen. They expect to publish the findings on affordance use and productivity next spring.

A giant monkey rock, that is how the office of the future might well look like

Sitting kills. RAAAF | Barbara Visser made with their Outstanding Landscape of Affordances a vision on the future of the workplace where the chair and the table are no longer the starting point. Barbara Visser is a visual artist and since 2014 chair of the recently re-established Society of Arts of the Netherlands Royal Academy (KNAW). This new work was commissioned by the Netherlands Chief Government Architect and motivated by a widely shared feeling of dissatisfaction with present-day standardized open spaces for “flex-working” as implemented at the various ministries, municipalities and universities.


Medical research has suggested that constantly sitting at work is bad for you. Even worse, a recent BBC News article noted: “We can’t simply fix it by heading for the gym.” Sitting kills. The BBC-article was titled: “Could offices change from sitting to standing?” Outstanding Landscape of Affordances shows how our offices could invite a more active and healthy life style. RAAAF | Barbara Visser presented an animation of a futuristic landscape of possibilities for working while standing up, a sculpture to be realized by the artists in Amsterdam later this year.


The mute animation ‘Sitting Kills’ shows a large rock-like structure. It is designed out of a thousand different possibilities for working in positions between standing and laying. The key is that the sculpture’s affordances stimulate people to take up different working positions during the day and promotes concentration. The richness of this landscape of affordances gives people the freedom to find the optimal position for their different tasks and needs during the working day. This vision presents a radical break with regular office furniture and current working models such as “flex-working”, which all are still based on sitting. In fact our societies’ entire surroundings are designed for being seated. This is a first step towards a future in which standing at work is the new norm. A lifelong health where we are both physically and mentally active.

This project is is also a next step in visualizing the landscape of affordances, this time focusing on possibities for standing, leaning and hanging provided by the monkey rock-like sculpture.
