Office Building Conversion- Spain. Image via Foster + Partners
Cities around the globe have widely adopted the concept of adaptive reuse and the importance of investing in historic sites and bringing them into the present day. Instead of focusing on brand new, ground-up construction, many are seeing the value in repurposing structure for new programs. Old churches are becoming restaurants, factories are transformed into museums and apartments, and warehouses are designed to become iconic office spaces. But beyond individual buildings, some planners and preservationists are reimagining what it means to revitalize in a similar way, but at a city scale, and how we can determine the buildings that would benefit our neighborhoods if they are repurposed.
Stilt houses are houses raised on piles over the surface of the soil or a body of water. Dating back to the Neolithic and the Bronze Ages, a wide variety of raised dwellings have been identified in a variety of forms worldwide, designed with several diverse and innovative methodologies. Stilt houses are well suited to coastal regions and subtropical climates. More than just a distinctive structural design resolution, they also protect against floods, maximize views and allow homeowners to build on rocky, steep, or unstable land. They also serve to keep out animals and vermin, provide ventilation from underneath, and minimize a house’s ecological footprint.
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.
