This architectural landmark Austin, Texas, was originally designed by Larry Speck, founding director of the Center for American Architecture and Design, and “juxtaposes austere concrete with sleek white pine floors and lofty wood-and-steel roof trusses,” according to the $9 million listing on Kuper Sotheby’s International Realty. The home will dazzle residents and visitors alike with unique details such as its kitchen wall made of lichen-speckled tree bark and kitchen island topped with white macaubas quartzite.
