In urbanism, One has learned how design can help simplify and smoothen complex puzzles, and, through that, to create space for others to engage in the city. One has extensive experience in designing the interrelationship between the city and its infrastructure, as well as the interrelationship between organizations, finances and territory. The latter expertise has proven very useful post-bubble, where One has unraveled and re-thought a number of area developments. One is at the forefront of sustainable, resilient urbanism and smart city technology.

The industrial area Albertkanaal is a business area that stretches from the center of Antwerp to Wijnegem. The area is the subject of a durable transition. With a team of specialists (POSAD, One Architecture, Arcadis and 3E) a concept study on the themes of energy and water is elaborated and will contribute to a sustainable future for the area. This study is approached in a holistic way: results are developed by developing business cases together with stakeholders, so that they are widely supported.
One Architecture has been responsible for the spatial design on the theme of water. Within this theme two business cases are elaborated:

The first case is investigating the possibilities of a greywater network, where water from a nearby sewage treatment plant will be reused within a (cluster of) companies for different processes, eg. cleaning of process equipment, process water, water treatment, steam generation, cooling and the sanitary. The study also examined whether rainwater that is collected from roofs can be reused within the company itself.

The second case examines possible measures for climate-adaptive space, to address problems such as risks of flooding and heat-stress which this area is dealing with. By zoning the area into smaller sections, it was possible to simulate possible rainwater-flooding risks, showing which areas and which of the stakeholders are at risk. A set of measures for climate-adaptation are proposed in the study. The business case focuses on one of the measures: a watersquare near the dock, which besides having water detaining capacity also serves as a recreational playground for the residential neighborhood.

One Architecture operates on a variety of scales, places and design fields. While working in these different realities and contexts, One recognizes the growing importance of digital technology and Smart Cities for today’s design questions. Often working as an integrator between different disciplines and agenda’s, One Architecture is more and more often using technology and technological tools. In the years One started to make technology and Smart City thinking part of both traditional projects and some special (research) projects. These projects evolve around four themes, each addressed with different, context-related, partners:

Smart Governance with The Mobile City. The rise of ‘big’ and ‘open’ data allows for new actors and new ways to get insight into urban infrastructures, salient urban issues as well as in opportunities for urban development. Next to that the rise of (social) media platforms provide citizens and institutions with new tools to organize publics around collective issues, mobilize people, and manage social infrastructural resources in collaborative ways. One Architecture works more and more as ‘arrangeur’ in citymaking processes.

Smart Data and Analytics with OSCity and Milan InnoVincY. A monolithic design process with a detailed cost/benefit analyses is increasingly ineffective. Digital technology can help navigate this complexity, enable an iterative design process, simulating processes and events and discovering the interplay of complex systems. One Architecture uses the integrative and innovative potential of design to unleash the possibilities of digital technology in planning. With this method, it becomes possible to think between different scales, optimize between different variables, study possible scenarios and discuss choices and effects.

Smart Mobility with Royal HaskoningDHV. Digital technology has a huge impact on mobility, both in the modes of transportation as well as in the (use of) physical infrastructure. Technology makes transportation more efficient, freeing up space for other uses. One Architecture understands how to design and transform cities such that future developments in mobility can be phased in. While designing for mobility, working with prototypes and beta versions gives the possibility to adjust a process in real-time.

Smart Fabrication with Waag Society and Filson and Rorhbacher. New relationships between designers and fabrication are made possible through digital fabrication. Digital technology and Building Information Modeling have changed the way our teams work and how our architecture is simulated. Using ‘direct prototyping’ and computer-aided manufacturing (CNC or robotics), One Architecture, with its partners, is constructing a number of projects.

The Big U/Dryline is a protective system that encircles Manhattan, responding to the needs and concerns of the island’s diverse communities. Stretching from West 57th Street south to The Battery and up to East 42nd Street, Big U/Dryline protects 10 continuous miles of low lying geography that comprise an incredibly dense, vibrant, and vulnerable urban area. The proposed system not only shields the city against floods and stormwater; it provides social and environmental benefits to the community, and fosters an improved public realm. Coordinated plans were created for three contiguous but separate regions of the waterfront dubbed “compartments. Each compartment comprises a physically discrete flood-protection zone that can be isolated from flooding in adjacent zones. Each presents unique opportunities for integrated social and community planning. The compartments work in concert to protect and enhance the city, but each compartment’s proposal is designed to stand on its own. Proposed solutions for the components were designed in close consultation with the associated communities and many local, municipal, State and Federal stakeholders; each proposal has a benefit-cost ratio greater than one; and each is flexible, easily phased, and able to integrate with existing projects in progress.

One Architecture is the urban planner and supervisor for Gouda Oost. In the past years, Gouda-Oost had become an (undeserved) symbol of the difficulties in new towns. When One started, in 2008, residents, municipality and housing corporations had already been cooperating for some time to transform and upgrade this neighborhood in Gouda without much success. In an essay, One Architecture suggested an adaptive ‘open’ plan that will be filled in piece by piece, by involving local authorities, stakeholders and especially local residents. With the urban plans for 3 different parts, One Architecture has now elaborated the first parts of the renewal.
The urban plan comprises a new, green, public area, the ‘Oversteek’ (traverse). The new and existing neighborhood facilities, like shops, supermarkets, a community school, the existing church and the mosque, are all situated along this area. The construction of the Oversteek is linked with the realization of an ambitious and diverse housing program, which will accommodate both existing and new residents, as well as special target groups. By dividing the housing groups into small plots the architecture will aid to showcase the newfound diversity.
The landscape is an important bearer of the developments in the neighborhood. Therefore, there has been an intensive collaboration with Lodewijk Baljon Landscape Architects. Central to this is the consolidation of the existing structure of green-bordered waterways.

One designed the urban plan and infrastructure for the Deventer Rivierenwijk. In 2008, housing corporation Rentree’s ambitious plans for the transformation of the Deventer Rivierenwijk, a so-called Vogelaarwijk, came to a slow stop. 300 houses were already demolished in the process, leaving a neighborhood torn to pieces.
One Architecture was asked to design an ‘essay’ on the future of the neighborhood. The essays main analysis focused on the arduous method of planning used in the past, in which every aspect and element was entangled with all other aspects and elements. One proposed an alternative way of planning and was commissioned to lead a new start.
One’s Urban Framework describes spatial starting points, conditions and directives. It indicates how the actors’ various spatial interventions, e.g. the reconstruction of the Amstellaan, 500 new houses, local facilities, neighborhood connections, and landscape structure, will combine into a coherent result. All obstacles obstructing the restart have been solved with the designs of the plan’s components.
An important feature in the design and how the neighborhood will function in the future was integrating and widening the Amstellaan, a main traffic artery. In the past, developers and engineers had imagined many options, all equally unfeasible and undesirable, all based on a pure technical infrastructural logic. One Architecture changed roles: by making the engineers subservient to the designers One Architecture created a new design. Suddenly, the design was within budget and received the full support of the area’s residents. Now, this design has been developed, tendered and is under construction, with an estimated delivery early 2014.
Further optimizations of the plan’s components are the result of this joint planning process. Investments in the integration of the Amstellaan also help the construction of Children’s Center. Project Amstellaan will result in a “tree bank”, making full-grown trees available cheaply for new construction. The green buffer space enables flexibility and room for optimization of Rentree’s housing program.
The various components can be elaborated within this Framework in a time and pace fit to the specific project. This also allows for the insertion of new insights in the project. It is therefore a result of non-linear thinking. The complexity of city, residents and its process have all influenced One Architecture’s design.

Dwarka is a new sub-city planned under the burden of providing growing population in 1990. It is strategically located close to the airport in South West Delhi and is planned for a population of one million-plus (primarily middle-class) inhabitants. From observations at the site and discussions with experts it is vident that development does not come off the ground, in part due to speculation, in part due to severe water shortages. Sizeable areas still stand vacant, and apartment buildings are only partly occupied. This is remarkable, given the fact that many areas much further from the center, the airport and the business-hub of Gurgaon are developing rapidly.
Water is key to a future development of Dwarka. As an essential building-block of any future vision or scenario for Dwarka, the water issue needs to be addressed first.
The aim is to develop strategies, projects and tools for addressing the (urgent) water. It is a parallel process where there are no fixed set of solutions but the idea is to test out to make Dwarka a more self-sustainable sub-city with alternate scenarios and by asking fundamental questions, spreading awareness for the urgency of the issue and at the same time demonstrating with appropriate action plans/concrete projects.
A site in size of 900m x 900m is identified around the station of Delhi metro for further study and strategy testing. Several proposals are put forward to solve current problems and bridge the gap between water consumption and supply. The designs aims to close water loop by increasing water-holding capacity, recharging groundwater, treating wastewater locally, implementing water design into landscape and architecture designs. The new road system aims for slow traffic and giving the space back to pedestrian. Meanwhile, roads are narrowed down in order to save more space for water management. Stormwater management system will be implemented into green structure for ecological and landscape value. The testsite will be a demonstration for other cases in the sub-city or in other areas of Delhi or India.

On December 21st Deventer’s city council approved the new master plan for the Jozef location. This master plan has been made by the city, in close collaboration with One Architecture.
The approval of this master plan shows the strength of organic urbanism. In 2008, One Architecture developed and designed a health center on a part of the site, in the former monastery that was part of the Deventer Hospital.
The design of the Jozef healthcare center has been done in a way that anticipated a connection to possible new program at the rest of the site. Soon after the opening of the healthcare center, Carinova decided to restart the development of the site and organized an invited competition. One Architecture won this assignment for 200 houses and a nursing home.
The prize-winning urban design proposes ‘organic’ and continuous growth of the existing complex. The elements – buildings around courts – were repeated several times. A public zone between the existing landmark building and the new buildings connects these units. The buildings are compact in order to maintain the green framework.
Besides the completed health center and the now-approved master plan, the re-use of the rest of the landmark building within the plan boundaries is now in progress. Here, One Architecture is designing two care units and Carinova’s public facilities as well as a kindergarten.
One Architecture takes pride in the fact that a relatively minor intervention, i.e. re-using a part of the existing building, has been fundamental in an incremental development of the entire site, connected to existing buildings and program.

For many years the area surrounding Leiden Central station has been below standard. It has been a cacophony of architectural ‘incidents’ in an area focused on infrastructure, lacking a proper connection to the city center and the university hospital.
NS Poort has invested heavily in the station, as a prototype of its ‘World Station’ concept, making the surroundings look even bleaker. This fifth station in the country by number of passengers has the appearance of a highway location.
One Architecture and NS Poort have developed a vision for the integral development of the area in order to persuade the city and other parties to start planning, together and integral.
The development vision comprises of a number of extraordinary elements: the large city blocks will be opened up for program and parking, a number of ‘stepping stones’ will reinforce the route to the city center (starting with a small cultural satellite at the station), and a structure with ‘urban entertainment’ and housing covering the bus station at the city side. At the sea side, a connection with the university hospital will be made with an integral solution for parking.
This vision has proven to be successful: All parties involved now work on this project, together and integral.

Kop van Isselt in Amersfoort is located on a strategic location close to the city center and in near proximity of highway and train station. Surrounded by several major urban development projects, Kop van Isselt can play a key role in the growth of Amersfoort.
Kop van Isselt has unique spatial qualities and a rich industrial history. Key elements in its character are the ‘backbone’ of the Nijverheidsweg, the connection with Amsterdamseweg and the existing (latent) structures such as the Warner Jenkinson area. Five different perspectives provided insight in the range of possibilities for Isselt. A financial quick scan and tentative schemes for phasing support the perspectives and helped to develop a long term vision for the area.

The proposal uses the existing cultural program and buildings on the site to create a diverse and unorthodox neighborhood. The future Viktoriakwartier is centered on an existing building that houses creative companies/individuals of Eindhoven, called TAC (Temporary Art Centre). A ‘young monument’ on the north side of the site, the Ventoseflat, will be restored. In order to create critical mass and additional liveliness, new residential and cultural program is added (between 25.000 – 30.000m²).
The urban context of this area is diverse: old small scale existing buildings and a big element: the PSV stadium. To deal with this, the scheme operates as a big block on the big scale and has streets along the TAC that contain small programs like shops, bars, workshops and so on. On the west side, a platform with towers is proposed to accommodate the needed program and to provide good light conditions for the inner streets and patios. The parts of TAC that were chopped off to make streets will be replaced as new volumes allowing TAC to grow organically in time. The whole project is linked by a newly proposed square to a future central axis between Eindhoven’s center and the developments in Eindhoven-West.
The scheme is devised in an intense dialogue with the four clients.

In the current hospital financing system, a successful re-development of this former hospital area translates directly into the cost of treatment.
The loose architectural organization of the existing complex allows, when repeated, for a similar freedom in the architecture of the new buildings. In the Beeldkwaliteitplan, the relationship between such aspects as volume, massing, materiality, style and size is formulated in order to establish the limits of possible differentiation while allowing maximum freedom. In its studies One found out that the pre-war parts of the hospital complex, called the SMCD, organized around a courtyard with ‘arms’ stretching into the landscape, would be well-suited for new, economically strong, demographic groups, people fed up with the boredom of suburbia and with a desire to live in an urban yet green setting. The complex will be converted into a mix of apartments and townhouses, with services attached.
Repetition of the SMCD is subsequently used to create a concept that extends the identity and quality of the pre-war hospital buildings onto the whole 8 hectare site, while allowing development in distinct parts under a common urban-, marketing and management plan. With One Architecture as its prime-consultant and planner, leading the team of specialists, in lieu of a commercial project developer, development revenues were channeled from the developer back to the hospital by selling at a later stage than is usual.

Together with city architect Azedine Al-Hamouti, Ouafaa Boutenache and supported by the Dutch Architecture Fund, One’s project sets an example for sustainable development.
Nador, situated on the Mediterranean Sea in the North-east of Morocco, is a fast growing city (from 20.000 inhabitants in 1960 till 170.000 now). The mayor of the City of Nador asked One to take the initial step in the process that would lead to the next phase in the expansion of the city by designing a new landmark and public area along the coastline ‘Le Corniche’. For the Corniche in Nador it is important to set an example, to make it beautiful with minimum front-end investment by the City, while allowing future development and economic activities and directing profits back into its economy.
In order to regulate the future growth of the program, a permit system is designed and put (literally) into place, by surfacing the Corniche with an elaborate triangular pattern in bi-coloured concrete: the permit system defines the placement and sequencing of the different programmes, so that there is an optimal situation at any stage of development.
The surface finishing will include drawn lines and icons indicating future development and different programmatic zones, and based on this system permits can be bought to establish stalls, shops, etc.
The Nador urbanism is ‘mission-oriented’ and focuses on the ‘software’, which allows for flexibility and adaptability to new developments.

The beauty is that traffic circles can easily be adapted to function as a local network, simply by adjusting traffic directions.
The circular traffic structure, with its possibility one- and two-directional traffic, uses a little less road surface than the municipality’s proposal. While the circular traffic structure might be a little cheaper, it looks much more expensive and as such generates a feeling of luxury in the area, both for the single-family housing and for the social housing.

In this 1998 study, One proposed a counter-strategy to the inner-city-suburbanization that endangered Eindhoven (as a result of Philips’ move to the High Tech campus) at the time.
Strijp-S would become, on short notice, completely ‘empty’ and would, because it is too big to develop quickly, draw functions that would be better located in other parts of the city (near the station, in the center or on the edge). Strijp-S would negatively influence the development of other sites.
That is why One have formulated a strategy for Strijp-S that can be characterized as ‘autistic’. The vision starts with creating a non-place in Eindhoven, an area that does not function and that does not have any relation with the surrounding city. This non-place can serve as an incubator for new, unforeseen or temporary developments (what has later been dubbed ‘the creative economy’). One called it an ‘experimental dystopia’.
It is the urbanism of ultimate generosity: it does not demand anything from the city, but could in the long term, in a completely unpredictable way, contribute much to Eindhoven as a whole.

The prize winning competition entry, with Noël van Dooren, for ‘Living along the Dikes’ drastically reorganizes the Dutch river landscape.
The heavily Ruhr-polluted topsoil needs to be removed from the floodplains in order to increase flow-capacity. When moved outside the area, the law says it needs to be cleaned at high cost. This project proposes to deposit the polluted soil on site, on the higher sandy grounds within the floodplains.

Six under a Tennis Court investigates the possibilities of an urban planning that is not suppressed by geometry.
The houses have a tennis court on their roof. This colossal order, as it is called in classical architecture, of tennis courts makes it possible to place each dwelling individually, with every architecture possible. It makes this area of Leidsche Rijn simultaneously into a park, thereby redirecting notions of the public and the private.
