As cities struggle to provide adequate and affordable housing, examining built examples of collective housing can help inform decisions about what to build and how. These projects offer opportunities to assess solutions, understand their limitations, and consider what might be applied elsewhere. In Paris, two recent examples combine apartments of different sizes with access to gardens, courtyards, and other outdoor spaces, working with structures already in place.

CHYBÍK + KRIŠTOF has opened Building the Existing City, an exhibition at Aedes Architecture Forum in Berlin that transforms the gallery into a working architecture studio. Running from October 23 to December 3, 2026, the exhibition centres on four architectural and urban design proposals for sites or urban situations in Berlin, selected through an open call. Over six weeks, visitors can follow the practice's research, discussions, and design work as the proposals develop, gaining insight into the processes through which architectural interventions are conceived in response to local conditions.

Delft-based practice Mecanoo has just released images of the renovation project for the Museum Boijmans Van Beuningen in Rotterdam, the Netherlands. The first images of the project were released in 2020, when the practice unveiled a proposal for a new wing as part of a larger renovation of the existing Museum Garden and a general reorganization of the layout to clarify circulation and connections throughout the complex. The comprehensive project includes a new building, the restoration and interior design of the existing premises, and a landscape project. The site, which has been closed since 2019 due to fire risk, water issues, overdue maintenance, and the presence of substantial amounts of asbestos, is a national monument expected to meet the updated standards and logistical requirements of an art institution of its kind.

In architecture, the word "pavilion" can describe an endless variety of structures. It might be defined as a principle and a typology, a freestanding structure, a temporary intervention, a gathering place in the city, or a space for experimentation. This last quality is what unites the six unbuilt projects featured here, all designed and submitted by ArchDaily readers. Here, the definition lies in their sculptural qualities and formal exploration, while their permanence and location vary according to each structure's purpose. The proposals also demonstrate another quality inherent to the pavilion: the intention to symbolically represent a stance. Their exploration of form and material thus also reflects a search for a sense of boundary, wonder, or a shared future.
