The word activist, long part of the vocabulary of social causes and political engagements, is an identifier gaining currency in architecture. As an era of “star architects” fades to be replaced by a generation eager to tackle local issues for everyday citizens, the shift has become the calling card of Santiago-based Grupo TOMA. Produced by ArchDaily as part of our partnership with The Architectural Review, the above film profiles the group of five friends – Mathias Klenner, Ignacio Rivas, Ignacio Saavedra, Eduardo Pérez and Leandro Cappetto – who have become an architectural collective interested in “the architect as a mediator, as an entity capable of linking organizations, of connecting political and economic powers."

For the past two and a half years, the group has sought out projects that convert industrial spaces of past eras into new facilities. Working without intermediaries has been a boon to the group’s experimental attitude and productivity, which might otherwise be curtailed by bureaucratic setbacks. With projects spanning from a few days to a few months, and some potentially longer, the group privileges social impact and memory over duration and material certainty.

Although global warming may only be partially to blame for California’s now four-year, record-breaking drought – intensifying it by 15 to 20 percent, say scientists – the long term implications of the weather phenomenon are a preview of a drier future with less predictable weather patterns.[1] As ecology and architecture begin to share responsibility in the implications of climate change, future solutions will need to balance architectural needs with ecological imperatives. Many designers are accounting for water scarcity in schemes for the drought-stricken state, but only recently have ideas addressed this issue head-on. “Grassroots Cactivism,” an award-winning proposal by Ali Chen, suggests that the drought-tolerant nopales cactus, with a variety of uses, is an ideal candidate for aiding water-conservation in California.

If Norman Foster were a household item, he would surely be a Swiss Army Knife. Foster, who turned 80 this year, is unrelenting in producing architectural solutions to problems that other architects can only theorize - just last Wednesday, for example, his firm released their design for a previously-unheard-of building typology, a droneport in Rwanda.

It is surprising then to find the man or his eponymous firm Foster + Partners absent from a list like Fast Company’s “The World's Top 10 Most Innovative Companies in Architecture,” organized into superlatives: MMA Architects, “for thinking outside the big box,” Heatherwick Studio, “for reimagining green space,” or C.F. Møller Architects, “for rethinking high-rise living.” This is not to say that Foster or his firm should be substituted for any of these deserved accolades, but rather that for five decades Foster and his firm have ceaselessly worked to enhance and expand on the human experience with architectural solutions that are both inventive and practical - a fact that is perhaps lost as a result of his position within the architectural establishment.

With that in mind, we thought it was worth highlighting the many occasions over the decades where Foster + Partners has shown themselves to be among the world's most innovative practices. Read on for more.

In It’s A Wonderful Life the film’s protagonist George Bailey, facing a crisis of faith, is visited by his guardian angel, and shown an alternate reality where he doesn’t exist. The experience gives meaning to George’s life, showing him his own importance to others. With the increasing scale of design competitions these days, architectural “could-have-beens” are piling up in record numbers, and just as George Bailey's sense of self was restored by seeing his alternate reality, hypothesizing about alternative outcomes in architecture is a chance to reflect on our current architectural moment.

Today marks the one-year-anniversary of the opening of Phase 3 of the High Line. While New Yorkers and urbanists the world over have lauded the success of this industrial-utility-turned-urban-oasis, the park and the slew of other urban improvements it has inspired almost happened very differently. Although we have come to know and love the High Line of Diller Scofidio + Renfro and James Corner Field Operations, in the original ideas competition four finalists were chosen and the alternatives show stark contrasts in how things might have shaped up.

On this key date for one of the most crucial designs of this generation, we decided to look back at some of the most important competitions of the last century to see how things might have been different.

There is perhaps no better display of modern architecture’s historical victory than Jacque Tati’s film Playtime. In it, a futuristic Paris has left-for-dead the grand boulevards of Haussmann, in favor of endless grids of International Style offices. The old city is reduced to longing reflections of Sacré-Cœur and the Eiffel Tower in the glass of these shiny new monoliths. But the irony central to the film is that this construction is created through mere surface treatments, and as the narrative unfolds, cheap mass-production withers in a world where the veneer has triumphed over craftsmanship and polish. In short, Modernism hasn’t always been all it's cracked up to be.

In the Museum of Modern Art’s new exhibition, "Endless House: Intersections of Art and Architecture," the simplicities of mass-market modern homes are abolished by artists and architects who, in examples from the 1940s to the present, have chosen to use the dwelling as a platform for universal messages and as an arena for architectural experimentation. In the same way that photography freed painting from the terrestrial concerns of realism, the simplicity of modernism liberated artists and architects to subvert extant conventions of buildings.

While the term “ecosystem services” may sound like a corporate antithesis to the course of natural order, it is actually an umbrella term for the ways in which the human experience is favorably altered and enhanced by the environment. Ecosystem services are therefore an important factor in creating cities which provide the maximum benefit to their residents with the minimal harm to their environment.

Aiming to find out how city planning can affect the provision of these ecosystem services, a new study published in Frontiers in Ecology and Environment by researchers at the University of Exeter's Environment and Sustainability Institute and Hokkaido University's Division of Environmental Resources evaluates the repercussions of rapid and fragmented urbanization and the possible detriment to ecosystem services and human well-being. In particular, the study is concerned with approaches to land-use and the outcomes they yield on the environment. Studied are two opposing tactics: a “land-sharing,” sprawl model (think Atlanta or Houston), or “land-sparing,” tight-knit urbanism (think New York or Tokyo).
