When we think of concrete, the color gray generally comes to mind. The traditional mixture of concrete, which comprises cement, gravel, sand, and water may vary in color depending on elements and admixtures but naturally varies from light to dark gray. However, compounds that add pigment to the mixture are becoming increasingly prevalent and popular, as they infuse the concrete with hues more stable than paint. These shades result from the addition of oxides: yellow, red and their derivations (eg. brown) are obtained with the addition of iron oxide; chromium and cobalt oxide create the greens and blues, respectively. For black concrete, it is common to use black iron oxide and carbon oxide combined with pozzolanic cement.

The staircase is a fundamental element for the connection of architectural spaces. But beyond its functional use, in many projects the staircase serves as a sculptural object, offering an opportunity for architects to generate creative spatial forms that animate the built space. In this installment of our Photos of the Week, we present 15 incredible staircases captured by photographers such as Patricia Parinejad, José Campos, and Brigida González.
Five projects have been selected as finalists of the 2015 EU Prize for Contemporary Architecture- Mies van der Rohe Award. The finalists were selected from a shortlist of 40 projects, and over the next couple of months the jury members will visit each of the finalist projects to evaluate the buildings firsthand and gather information from the people who use them. On May 7, the architects will present their projects to the jury. The winner will be announced the following day at a ceremony at Mies van der Rohe’s Barcelona Pavilion.

Known for his superior design and unparalleled craftsmanship, the 2009 Pritzker Laureate and 2013 RIBA Gold Medal Award winner, Peter Zumthor, was recently invited to speak at the School of Architecture in Tel Aviv University. In a lecture titled “Presence in Architecture - Seven Personal Observations,” Zumthor shared some of the inspirations behind his greatest projects, giving us insight into his poetic, intelligent, (and some might say) “nearly divine” mind.
