City x Space: Cross-Section Thinking

How can the integral and multifunctional use of public space, subsurface, and buildings -within a densified urban environment – create space and value that contribute to an attractive and future-proof living environment?

“This seminal question generates various answers depending on the specific context and location of asking. International interdisciplinary students from Delft University of Technology have outlined various design solutions. Manifest in all cases are the spatial bottlenecks on the level of public space. Connecting the intervention areas with the surrounding socio-spatial networks therefore forms the basis of all solutions. In addition, in the densification challenges we see the attention for the multi-layered space: on the one hand, a train or metro station, for example, generates flows of people at several levels; on the other hand, building in higher densities and/or living and working in collectives, generates new shared spaces.” As Maurice Harteveld explains in the exhibition; “The hybridization of the urban and architectural program also requires a cross-section thinking. This can be seen in future-proofing both large-scale sports or industrial areas, as well as small-scale residential houses in neighborhoods where work is shifting to local entrepreneurs and home workers. Finally, the subsurface plays an important role in greening the living environment and in water storage.”

City x Space

In the spring of 2021, the Delft University of Technology, COB Platform of Subsurface Construction, the Environmental Department of the Flemish Government, and the Deltametropolis Association have started a design study exploring the possibilities of integral and multifunctional use of space within highly densified cities. Design consortia from practice have been invited to choose from a number of cases in The Netherlands and Flanders involving spatial bottlenecks in ​​public space, subsurface, and buildings. Seven teams have already started.

Underground Use of Space as a Game-Changer
Due to the convergence of a multitude of tasks and transitions (energy, climate, circularity, mobility) in ever densifying cities, the pressure on public space is increasing. It is especially today because these cities also have to absorb a large share of the housing assignment, following the aims to preserve the rural landscape as well as to reduce the pressure on the current mobility system. However, how much densification is (still) possible for locations that are already overloaded with functions and programs and where the public space – both above ground and below ground level – threatens to silt up and get stuck?

Current and future space claims require careful consideration of the options for using space more effectively and efficiently, with the aim of increasing the ‘spatial efficiency’ of the city in an innovative way.

In the design study, partners focus on a different view of the organisation of urban programmes and transition tasks while they search for new ways of thinking, patterns, and solutions for integral and multifunctional use of space from the cross-section.

The central question:

How can integral and multifunctional use of public space, subsoil, and buildings within a densified urban environment create space and value that contribute to an attractive and future-proof living environment?

The design study has resulted in various spatial designs with visions of the future and implementation strategies. A number of urban locations as case studies are being worked on, namely Ostend, Rotterdam, Amsterdam, Mechelen, Leuven, and Maastricht. For each case study, a multidisciplinary team was selected (in Rotterdam 2) of spatial designers (architects, urban planners, landscape architects), engineers, and the experts required for underground developments such as geo-technicians.

Creating Value through Public Space

The United Nations just launched the ‘UN-Habitat State of the World Cities Report 2020 on the Value of Sustainable Urbanization‘. “COVID-19 has transformed our urban world. However, it does not signify the end of cities. Urban areas hold the key to resilient, green recovery, and building back better!”, Victor Kisob, th assistant Secretary-General and Deputy Executive Director of UN-Habitat states. The United Nations emphasises that we create “value through public space”. This includes interior public spaces, which were closed due to COVID19-induced lockdowns recently. In this case, “local governments must work to provide sanitation infrastructure in all public spaces in order to mitigate the health risk”. Yet, also, “when designed with climate adaptation, mitigation and resiliency, components of cities from buildings to public spaces can create communities that enhance environmental values”. They also enhance social and economic values. “Cities can unlock the intangible value of sustainable urbanization by creating public spaces and opportunities for democratic participation and social inclusion that allow the cultural fabric of urban life to flourish”. And, public space can offer a livelihood for people to be entrepreneurial and take part of labour work. Equality plays a huge role in sustainable urbanisation. “Diversity contributes to the social, economic and environmental value of urbanization through tolerance, integration, and coming together in public spaces.” This includes for instance the representation of the urban poor, migrants, and cultural minorities, hence this should lead to prioritising “their needs in any decision-making process, be it about the urban commons, atmospheric commons, public spaces or resource use”. And, “engage a wider audience – e.g. children and youth – in urban planning and design processes for safe, inclusive and accessible public space.” Everyone should “understand their rights to access public spaces and services”. I would like to add: Our challenge is to contribute to the design of public spaces for everyone.

Public Space in the Entrepreneurial City

New public spaces have emerged in the entrepreneurial city. Their existence relates to entrepreneurial action of public governments, of the people, inhabitants of the city, and of entrepreneurial alliances of civic actors. The entrepreneurial way of governmental action led particularly to new spatial conditions and typologies as governments delegated the responsibilities for the production and management of public space to private actors. This extended the debate to the city’s public space in its ubiquitous shopping malls and private residential estates. Secondly, the opportunities which the city offers for the entrepreneurial contributions of general citizens, migrants, and refugees, relate to its public spaces too. Characterised by the proximity of mixed land-uses and flexible building typologies, as well as a well-connected street network and high density, the new urban typologies, effecting public space in their socio-economic nature, are found in many places, using the same models concerning citizens initiatives and popular action. Lastly, new emerging alliances of actors form the relationship of the ‘entrepreneurial city’ and public spaces. These alliances of civil society groups comprise old and new NGO’s, academics and activists, and start-ups of social enterprises launch own initiatives to co-designs alternative community spaces, more affordable and communicative workspaces, and build capacities. Such trends can be seen in cities worldwide too and start to create new forms of public spaces, which facilitate social interaction while creating more micro-economic opportunities.

Stand up for Public Space

Global Campaign to Support Public Space at the 10th World Urban Forum
on 8-13 February 2020, taking place in Abu Dhabi


Future cities need public space for a more human(e) togetherness!

In August, City Space Architecture launched a global campaign to support public space, inviting global stakeholders to join forces in order to ask the WUF Secretariat to include a clear reference to public space in their Concept Note. The campaign attracted strong interest, with insightful statements from urban experts and activists. After that, the Concept Note has been revised, now public space is included in the document and this is a great achievement.

African Public Spaces?

What is public space in African? Does it exist as we may presume? At the current, we are analysing and comparing urban life and presumed public spaces in selected segments of four African cities to map what we know about these cities. It is a first step in deepening cross-cultural understanding: An exiting start of a new exiting scientific journey along Dakar in Senegal, Dar es Salaam in Tanzania, Maputo in Mozambique, and Lusaka in Zambia.

Public Space: Changing Values

The Quest for Public Space: Changing Values in Urban Design, The City as Learning Lab and Living Lab

This article highlights the dynamics of values in our reasoning on public space. By means of an epistemological study, it tests the contemporary premises underlying our ways to safeguard the inclusive, democratic, agential city, and, as such, it aims to update our view on urban design. The article raises three subsequent questions: [i] Is the city our common house as perceived from the Renaissance onward, containing all, and consequently are public spaces used by the people as a whole? [ii] Is the city formalising our municipal autonomy as emphasised since the Enlightenment, in an anti-egoistic manner, and in this line, are public spaces owned by local governments representing the people? And, [iii] is the city open to our general view as advocated in Modern reasoning, restricting entrepreneurial influences, and synchronically, is its public spaces seen and/or known by everyone? – Inclusiveness, democracy, agentiality are strongholds in our scientific thinking on public space and each issue echoes through in the practice on urban design. Yet, in an aim to keep cities connected and accessible, fair and vital, and open and social, conflicts appear. Primarily based upon reviewing urban theory and particularly experiencing the Amsterdam for this matter, the answering of questions generates remarks on this aim. Contemporary Western illuminations on pro-active citizens, participatory societies, and effects of social media and micro-blogging forecast a more differentiated image of public space and surmise to enforce diversification in our value framework in urban design.
