Our projects



Focus on essential targets

To address the challenges of the foreseen complexity of the spatial development in the future, in 2015 Basic City A+U and Arons en Gelauff Architecten established a strategic and long-term joint venture – ROAM.

The principal aim of ROAM is to set up a strong qualitative relation between urban and architectural scales. We believe that a profound interdependence of these two levels of our discipline is essential for the quality and long lasting values of the future urban developments. No architecture should be produced detached from urbanism. No urban plan should be made indifferent to architecture.

With ROAM, we have created a practice of urbanists and architects who are able to:

  • Produce long-lasting sustainable urban plans that create conditions for the realization of the high-quality architecture
  • Multiply the qualities of the urban plans through the conceptualization and production of specific yet well integrated architectural objects

ROAM is a young office with a lot of experience. It combines state of the art knowledge in architecture and urban planning to make integrated solutions for cities, quarters and buildings. Instead of teaching how, we involve in processes that develop according to the needs of all stakeholders.

ROAM’s portfolio presents both, our ability for conceptualization and realization of architectural projects and our expertise and experience in large scale urban projects.

ROAM speaks many languages: English, Chinese, Dutch, Italian, Russian…

ROAM consists of ROtterdam and AMsterdam.

ROAM mixes ability to conceptualize and execute large scale urban regeneration plans with precision and a profound sense for the articulation of the architectural form. As such ROAM is capable of adding essential qualities to almost any given urban situation, regardless its scale or complexity.

ROAM also stands for Research and Operations in Architecture and Masterplanning.

ROAM matches each project with the right people from its dedicated and motivated team.

Tactical plans

A toolbox for adaptable urban development

ROAM aims at finding the fundamental values in city development, in both architecture and urban planning. We believe that the increasing complexity and persistent volatility of socioeconomic conditions call for a reduced and more precise selection of essential targets in city development.

Time of a great visionary blue print masterplan is long gone. Instead ROAM opts for tactical urban plans that enable planners to envision urban development that is adaptable to the changes of the context through time. As such the tactical plans become the optimal solution for dealing with the ever growing volatility of worldwide urban conditions.
Tactical urban plans operate through defining development strategies for a number of carefully selected, site related and essentially independent aspects: public and green space networks, vehicle, pedestrian and slow traffics systems, urban grain, density distribution, massing principles, architectural guidelines, implementation procedure, etc.
While reaching their full potential when realized in accordance with the others, every strategy itself keeps a high level of independence and secures the delivery of many qualities to a site. As such, the tactical plans become responsive and adaptable to the changes in the context and enable long term urban development towards better living and working conditions in cities. In a pursuit of a happy future, that is both, ambitious and realistic!

Straightforward architecture

Turning typical briefs into specific buildings

Our architecture solves problems.
It follows simple and understandable logics. It sends an open invitation for all those involved in the processes of conceptualization, realization and exploitation of our buildings to engage in reflecting our production. This is, from our extensive experience, proven to be the most effective tool for achieving designs that are satisfactory for the end users.

We aim at creating beautiful and very specific architecture from seemingly ordinary briefs and programs. We thoroughly analyze the local conditions of the sites we work on, as well as briefs and budgets of the projects. We recognize challenges and deal with them by proposing daring and appealing concepts. We carefully design basic elements, such as dwelling units, and arrange them playfully to fit within the concept. With this ‘joy in repetition’ we manage to create unique projects.

While we want our buildings to shine with uniqueness, we also see them as performers within a wider urban ambient. Looking at them as such, our design approach aims at conceptualization and realization of the buildings that are capable of contributing and enhancing the context they are made in.
Our buildings become pleasurable and sustainable architectures, equally appreciated by the general public as well as by the professionals in the architectural field.

An attitude instead of ideology

Context is essential

Our approach to architecture and urban planning is based upon an open and accurate attitude towards the reality, instead of a precise and more rigid definition of our design ideology. Through our projects, we engage with the contemporary design paradigms and methodologies, navigating between their potentials and limitations.

We believe in a specific rather than general applicability of the concepts like: accessible, diverse, open, mixed, sustainable and alike. What is an accessible urban district in Europe could be unimaginable in China. What is a diverse neighborhood in Amsterdam could easily be dull in Hong Kong. Working worldwide we learnt to keep our vocabulary alive and continuously recalibrate definitions of the concepts for the urban space as the primary means to be able to address specificity of the local situations we face in our projects.

We aim at…

Our guiding principles

Integrated plans

Adaptable urban development frameworks that organise program, infrastructure and landscape. Human, sustainable and financially feasible.


Plans accessible to everybody, that enable a wide stakeholder participation and stimulate program exchange.


Plans that achieve maximum outcomes with minimal means, by recognising and exploiting the key potentials from the context.

Multi-scalar concepts

Quality at all scales. Architecture that enriches urbanism and urbanism that enables advanced architecture.

Multiple meanings

Urban development that is critically interpreted and appropriated by all key stakeholders in a specific context.

Our working method

Simple steps towards high quality projects

  • Understanding: Through the analytical approach and intensive communication we help our clients establish and secure the most essential goals in the projects.
  • Conceptualization: articulation of an adaptable architecture/urban development framework is in the heart of this phase. Its main role is to distinguish between fixed and flexible design parameters.
  • Orientation: interpretation of flexible parameters and visualization of the resulting key development scenarios are the main actions in this stage of the process. They help the clients calibrate and optimize their ambitions.
  • Implementation: selection of the optimal scenario through a process of careful evaluation and definition of phasing strategy for its incremental realization are the key focus of this stage.
