High-Tech Skyscrapers Could be Built with Low-Tech Wood

When we think of wood construction, we often think of log cabins, tree houses, or the framework of residential properties. But if a new start-up has its way, we might soon be gazing up at 12-story buildings made almost entirely out of Douglas firs.

In a report for CityLab, journalist Amanda Kolson Hurley profiled Portland, Oregon's Lever Architecture, a firm attempting to revitalize wood-based towers that reduce the carbon footprints of conventional buildings. Their offices are located in a four-story property made from wood; their next major project, titled Framework, is expected to be 12 stories and slated to debut in Portland in 2019.

Part of Lever’s goal is to reduce concerns over wooden structures—namely, that they’re prone to fire hazards or might not be structurally sound in an earthquake. Developers use a building material called mass timber, a special type of strengthened wood in which timber panels are glued together to make beams and cross-set layers for walls and floors. Fire tests have shown the mass timber doesn’t ignite easily: It chars, which can insulate the rest of the panel from the heat. Strength testing has shown the layers aren’t easily jostled by outside forces.

Lever’s architects hope that wooden buildings will lessen the environmental impact of commercial towers that use concrete and steel, which are responsible for 10 percent of greenhouse gas emissions during their manufacturing.

Other firms have designs on taller buildings, including one 35-story tower in Paris and a 24-story building in Vienna.

Futuristic New Street Toilets Are Coming to San Francisco

San Francisco’s streets are getting shiny new additions: futuristic-looking public toilets. Co.Design reports that San Francisco’s Department of Public Works has chosen a new design for self-cleaning street toilets by the architectural firm SmithGroupJJR that will eventually replace the city’s current public toilets.

The design is a stark contrast to the current San Francisco toilet aesthetic, a green knockoff of Paris’s Sanisettes. (They’re made by the same company that pioneered the Parisian version, JCDecaux.) The tall, curvy silver pods, called AmeniTREES, are topped with green roof gardens designed to collect rainwater that can then be used to flush the toilets and clean the kiosks themselves. They come in several different variations, including a single or double bathroom unit, one with benches, a street kiosk that can be used for retail or information services, and a design that can be topped by a tree. The pavilions also have room for exterior advertising.

“The design blends sculpture with technology in a way that conceptually, and literally, reflects San Francisco’s unique neighborhoods,” the firm’s design principal, Bill Katz, explained in a press statement. “Together, the varied kiosks and public toilets design will also tell a sustainability story through water re-use and native landscapes.”

San Francisco has a major street-poop problem, in part due to its large homeless population. The city has the second biggest homeless population in the country, behind New York City, and data collected in 2017 shows that the city has around 7500 people living on its streets. Though the city started rolling out sidewalk commodes in 1996, it doesn’t have nearly enough public toilets to match demand. There are only 28 public toilets across the city right now, according to the San Francisco Chronicle.

These designs aren’t ready to go straight into construction first—the designers have to work with JCDeaux, which installs the city’s toilets, to adapt them “to the realities of construction and maintenance,” as the Chronicle puts it. Then, those plans will have to be submitted to the city’s arts commission and historic preservation commission before they can be installed.

Dutch City Will Become the World's First to Build Inhabitable 3D-Printed Concrete Houses

A new 3D-printed concrete housing development is coming to the Netherlands in 2019, CNN reports. The structures will be the first habitable 3D-printed concrete houses in the world, according to Project Milestone, the organization behind the initiative.

While architects and engineers have been experimenting with 3D-printed buildings for several years, most of those structures have just been prototypes. The Dutch development, located in Eindhoven, is expected to be ready for its first residents by mid-2019.

Project Milestone is a collaboration between the city of Eindhoven, Eindhoven University of Technology, the contractor Van Wijnen, the real estate company Vesteda—which will own and manage the houses—the engineering consultancy Witteveen+Bos, and the construction materials company Weber Beamix.

The five planned homes will be built one by one, giving the architects and engineers time to adjust their process as needed. The development is expected to be completed over the next five years.

The housing development won’t look like your average residential neighborhood: The futuristic houses resemble massive boulders with windows in them. The first house, scheduled for completion in 2019, will be a 1022-square-foot, three-room home. It will be a single-story house, though all the rest of the homes will have multiple stories. The first house will be built using the concrete printer on the Eindhoven University of Technology’s campus, but eventually the researchers hope to move the whole fabrication process on-site.

In the next few years, 3D-printed houses will likely become more commonplace. A 3D-printed home in Tennessee is expected to break ground sometime later in 2018. One nonprofit is currently trying to raise money to build a development of 100 3D-printed houses in El Salvador within the next two years. And there is already a 3D-printed office building open in Dubai.

In Eindhoven, residents appear to be fairly eager for the development to open. Twenty families have already applied to live in the first home.
