First established in the Flemish Region and in Antwerpen at the end of the ‘90’s, the function of “bouwmeester” has been introduce in Wallonia which created, in 2007, the Architecture Cell of the Wallonia-Brussels Federation. In 2009, the Brussels Government chose the first bouwmeester for a five-year term. Charleroi followed the movement and nominated its bouwmeester, keeping the Flemish name. In the following years, the city of Gent will choose its bouwmeester too.

The bouwmeester’s main role is to help clients to ensure the quality of regional public projects in terms of architecture, urban planning and public space. That role was now extended to projects carried out by the municipalities and the private sector, given that these have a major impact on the urban development of Brussels. Thus, the bouwmeester and his team are responsible for assisting, advising and encouraging public and private clients, using a variety of tools that have been developed since the creation of the function.


The general approach of the bMa can be summed up in four points:


The bouwmeester takes the view that architectural quality is not defined purely in terms of aesthetics but also and above all in terms of spatial quality. Spatial quality is the product of multiple factors: integration into the urban fabric, functionality and user-friendliness of the building or site, social interaction generated by the project, sustainability, economic use of resources and so on. It is also dependent on an efficient preliminary process and the support of the population and users.

Thus, spatial quality promotes community life and leads us to re-examine our social values. This is why a properly conducted discussion leading to a common definition of the spatial quality of a project is so important. The bouwmeester’s role here is therefore to ensure that this discussion takes place under the right conditions. The discussion must be transparent, well-argued and lasting, so that the definition of spatial quality becomes a value shared by all parties.



Brussels is spatially, socially and administratively complex. It is therefore essential for the bouwmeester to build bridges between the various actors involved in urban development, at the level of public actors (administrations, institutional authorities) and private actors (owners, real estate developers), but also at the level of the city’s inhabitants and users, civil society organisations and engaged citizens working to improve the city. Building bridges, but also encouraging coherent urban development – such is the bouwmeester’s approach.

The bouwmeester’s neutrality is essential to perform this role successfully. He does not support any particular sector, but brings together people, services and disciplines and aims to take a comprehensive approach. While reporting to the government, the bouwmeester must be able to express independent views about the projects he handles.



Although Brussels shows ambition when it comes to urban regeneration, this does not always translate directly into achievements on the ground. The work of the first bouwmeester, Olivier Bastin, created a favourable climate in architecture and urban planning, in particular through the introduction of a high-quality competition culture.



The foundations of the bouwmeester’s mission were laid by the first holder of the post. The requirement now is to go even further by broadening and deepening the bouwmeester’s sphere of action by means of more competitive tenders, procedures, building owners and missions, but that is not all.

More intensive support has been introduced both prior to and following project conception: in the former case through the use of the research by design method, which contributes to a better spatial understanding of the Region, and in the latter case with the principle of the quality chamber, which involves the bouwmeester in the monitoring of projects in order to guarantee their smooth progress through to completion.
