Following five years of construction, Portuguese architecture firm Aires Mateus has completed its awaited mudac: museum of Contemporary Design and Applied Arts in Lausanne, Switzerland. The sculptural building is part of a new cultural district and urban regeneration plan promoted by the Canton of Vaud, the City of Lausanne, and the CFF (Swiss Federal Railways), which features three art museums that translate the memory of the site, echoing its former industrial status with prismatic geometric forms, concrete surfaces, and sharp lines.

During his latest esplanade in Switzerland, architectural photographer Paul Clemence captured the newly inaugurated museum, highlighting its unique concrete geometry, play of shadow and light, and how the architecture complements its surroundings.

The threshold is a constructive element of the floor that serves to finish when there is a notable change in material or level. Much more prominent in the past, the piece today has a more discreet presence in architecture.

The thresholds and transition strips are applied directly to the floor and are responsible for making the transition when there is any change in the built space, whether it is in level, in the type of floor, or even when there is a door or passage.

One of the central responsibilities of urban planners and designers is to create places within the city for gatherings, demonstrations, leisure, and relaxation. The following list of unbuilt public spaces presents projects that expand these spaces beyond the shores or riverfronts, return misused spaces back to the local communities and seek to optimize otherwise overlooked areas. These types of interventions are essential in improving the quality of life of the citizens and in making cities more enjoyable to live in.

This week's curated selection of Best Unbuilt Architecture highlights projects submitted by the ArchDaily community. Located near a UNESCO heritage site in Italy, on top of an illegal dumping site in Dallas, Texas, or in a medieval city in northern Spain, this round-up of unbuilt projects showcases how architects and urban planners recognize the potential of urban places.

The use of earth-based materials appears in two practices throughout history: in the construction of buildings and – far less commonly known or conclusively understood – in certain dietary consumption patterns. To put it simply – soil, the most important nutrient collector on earth, can be used for both building and for eating.

Liam Young is a speculative architect, product designer, and director who operates in the spaces between design, fiction, and futures. Young specializes in designing environments for the film and television industry, harboring the belief that creating imaginary worlds grants us the ability to connect emotionally to the ideas and challenges of our future.

Following the centuries of colonization, globalization, and never-ending economic extraction and expansionism, humans have remade the world from the scale of the cell to the tectonic plate. Young suggests in a TED Talk, “What if we radically reversed this planetary sprawl? What if we, as humans, reached a global consensus to retreat from our vast network of cities and entangled supply chains into one hyper-dense metropolis housing the entirety of the earth’s population?"
