Holl focuses on a collection of peculiarly American house types. These building forms exhibit a simplicity and integrity of construction and expression that link folk to modern architecture, and they offer a framework for thinking about alternatives to suburban tract housing.

Participants in the Pamphlet Architecture 30 competition were asked to respond to the theme "Investigations in Infrastructure," and propose new directions for architecture, transportation, energy, cities, and agriculture at a continental scale. The winning entry, Coupling, imagined six daring projects: a high-speed rail system across the Bering Strait that also collects freshwater from the seasonal iceshelf; a decommissioned airport transformed into a geothermal data farm and agriculture site; thickening on/off ramps around "big box" stores into circular parking lots; a call to include landfills in the list of preserved open spaces; and a saline terminal lake turned into a water farm, recreational retreat, and habitat haven. Coupling argues that infrastructures behave as artificially maintained natural systems. Rather than a New Deal approach of massive engineering or iconic infrastructure, Coupling employs adaptable, responsive, small-scale interventions whose impacts are global in scale.

In 1977 Steven Holl and William Stout created a grittier alternative to mainstream architectural publishing called Pamphlet Architecture. With Holl's Bridges, the landmark series was born, and for 30 years Pamphlet has served as soapbox and laboratory for such notable architects and theorists as Lebbeus Woods, Zaha Hadid, Lars Lerup, and Michael Sorkin. With its twenty-eighth installment, Pamphlet Architecture celebrates its thirtieth anniversary no less bold than when it began. Augmented Landscapes features a landscape architecture practice for the first time in Pamphlet history. London's Smout Allen presents five projects that respond to the way in which man has enlarged the landscape through architecture and infrastructure, manipulating and blurring perceptions of what is natural and what is artificial.

The thirteen projects take as their subject a site of contested transportation infrastructure--the Sheridan Expressway. By proposing new typologies for this site, these studies seek to mediate the spaces in the city where local and regional meet. Referencing the introduction of the modern parkway into the Bronx, the grading of the Central Park transverse roads, and other works that have redefined the relationship between parks and roads, author Jonathan Solomon suggests a system by which large projects might again be built in American cities.

This newest addition to the Pamphlet Architecture series, long admired for its willingness to propose architectural solutions to challenging problems addresses the issue of rising sea levels with an interrogation of the concept of floating cities, a field of inquiry gaining increasing relevance and urgency with the impending reality of climate change. The authors explore notions of buoyancy and the amphibious through a typology based on human response and adaptation, to one of the hosting pressing issues of our day.

We all know that today's architectural design has moved from the sketchpad to the screen - the era of the Mayline and the drafting board now seems downright Paleolithic - but techniques for using the computer not just as a tool for rendering but as a generative instrument remain woefully unexplored. The technologically progressive young firm Aranda/Lasch illustrates how advanced computational methods and algorithmic codes can be used to foster architectural design. "Tooling" explores patterns generated by computer codes that in turn create an organizational template assembling projects. By openly sharing these codes, the authors seek to foster further investigation into their methods, allowing other architects to model and evolve more critical and insightful geometries and patterns.

For fifteen years, three architects--James Cathcart, Frank Fantauzzi, and Terence van Elslander--from three different cities have held an ongoing collaboration, creating installations and other works of innovation and art about the act of building. Pamphlet Architecture 25: Gravity catalogs a cross section of their many works, from the portable toilets installed in the facade of New York's StoreFront for Art and Architecture to "Big Orbits," a giant solid and a giant void constructed from 4600 shipping palettes. Although strongly conceptual, their work reminds us that a primary function of architecture is to engage the public.
