For its first exhibition at the Arsenale and unlike in previous years, the organiser LUCA – Luxembourg Center for Architecture decided, in agreement with the commissioner, the Luxembourg Ministry of Culture, to not launch an open call for projects, but to rather take over the conception and production of the exhibition itself. In order to highlight the country’s competences in architectural research and the Baukultur, LUCA – Luxembourg Center for Architecture chose the Master in Architecture of the University of Luxembourg as its curating partner.

The way we deal with land has a decisive influence on architecture and urban planning. In the past decade, the privatisation of land and speculation with especially municipal land have risen dramatically. Many European cities that are, like Luxembourg, under high developmental pressure have practically no more of their own land available for construction. Although this problem is primarily a challenge for politics, many architects are also addressing it from a design point of view. The Luxembourg Pavilion is engaging with the most radical of these approaches – elevated buildings that allow the land to remain open, both physically and symbolically. Various projects from the history of ideas enter into dialogue with contemporary experiments that share the aspiration of making the land accessible to public uses. In doing so, they are resisting an alleged logic that has led to an almost universal privatisation of land in cities, creating isolated enclaves and reducing the public sphere. « The Architecture of the Common Ground » is not a plea for a thoroughly elevated city, but an appeal to understand the finite and indispensable land as an inalienable common good, like air and water. Only then will we be in a position to further develop our cities in socially and environmentally sustainable ways.

On the first level, the exhibition uses a spatial installation to tangibly illustrate the issue of the privatisation of land. Right at the start, visitors are led into a central corridor which only opens up to the exhibition space at the other end. The corridor takes up eight per cent of the floor area of the entire exhibition space. This projects the situation in Luxembourg onto the exhibition space, illustrating that public authorities only have a remaining eight per cent of building land at their disposal. Positioned around this installation, in the form of models at a scale of 1:33, is a selection of 13 as yet unrealised elevated projects from the history of ideas. The focus here is less on the objects themselves than on the space between land and object which is made available to the public even in the context of a privately owned property. The various projects not only clearly illustrate how much variety the elevated building typology can yield – from slab buildings and towers to clusters and urban block developments – but also how manifold the design and use of this porous ground-floor space can be.

The large-scale diagram is designed as a work in progress. Based on research on an Architecture of the Common Ground conducted by master’s students at the University of Luxembourg, visitors are invited to continue writing the atlas of a committed architecture that sets the value of the public sphere and participation above the privatisation and encapsulation of urban land.
