The Cliff Café juts out of a precipice to serve up some amazing views to go with its food and beverages. Designed by Trace Architecture Office, it's also joined by the striking Tower House nearby, which similarly puts the focus on the view.

Sublime Cement says it's ready to start scaling on the "world's cleanest cement," which meets industry performance standards relying on room-temperature electrolyzers in place of fossil-fueled furnaces, using a variety of zero-carbon input materials.
-
Researchers have made concrete 30% stronger by replacing a percentage of sand with spent coffee grounds, an organic waste produced in huge amounts that usually ends up in landfill. The method offers a greener approach to construction.
-
MIT researchers have discovered that when you mix cement and carbon black with water, the resulting concrete self-assembles into an energy-storing supercapacitor that can put out enough juice to power a home or fast-charge electric cars.
-
Working with private industry, the University of Cambridge has gone one step beyond 3D printing with a concrete infrastructure unit that was not only made in an hour, but incorporates sensors to make it self-monitoring and, one day, self repairing.
-
Traffic is among the biggest sources of air pollution, but what if the very roads they drive on could help clear the air? Engineers in Korea have now demonstrated that photocatalytic concrete can help reduce pollution in tunnels.
-
In an effort to create low-cost, sustainable housing, researchers have created a composite material by replacing sand in concrete and mortar with a common, non-degradable waste product: used disposable diapers. But would you build your house with it?
-
Concrete is one of the largest single sources of human-induced carbon dioxide emissions. Engineers at Washington State University have now developed a new method for making concrete that absorbs more carbon than it emits.
-
3D concrete printing (3DCP) technology is already known to offer a more efficient approach to constructing buildings. A new type of 3DCP is said to be better, resulting in walls that are a claimed 72% lighter than their conventional counterparts.
-
After water, concrete is the world’s most consumed material, and concrete production’s impact on the environment is significant. Researchers have discovered that an inexpensive ingredient may be the answer to reducing concrete's climate impact.
-
The production of the cement is a major source of greenhouse gas emissions, which is why some people have tried replacing it with fly ash. A new technique makes that fly ash more eco-friendly, resulting in concrete which is greener and stronger.
-
Concrete has been used in construction for thousands of years, it's everywhere. But its production is a major contributor to global carbon emissions. A project spun out of VTT Finland is looking to make concrete manufacture carbon negative.
