The recent death of President George H.W. Bush occasioned assessments of his administration’s legislative achievements, one of which was the far-ranging Americans with Disabilities Act (ADA), a civil rights act signed into law in 1990. The law included accommodations for people with disabilities in buildings. In the ensuing decades the ADA has had a significant impact on the design and construction of the built environment in the U.S. To gauge the impact of ADA, how it has evolved, common misconceptions about ADA, and its role in promoting social equity in architecture, I spoke with Peter Stratton, Senior Vice President and Managing Director of Accessibility Services at Steven Winter Associates, who works with architects and others in the construction industry on the application of the ADA design standards. (I worked at the Connecticut-based Winter firm between 1996 and 2006; Stratton was a colleague.)

Design practice Snøhetta has created a series of secluded wooden shelters for Norway's largest hospitals. Sited in the forest, the shelters were created on behalf of the Friluftssykehuset Foundation. Designed to make hospitalization easier for patients and their families, the outdoor retreats offer a physical and psychological respite from treatments and the isolation that can follow long-term hospitalization.

Researchers at New York’s Columbia University have unveiled a method of vibrantly replicating the external and internal structure of materials such as wood using a 3D printer and specialist scanning techniques. While conveying the external profile and patterns of natural objects is tried and tested, a major challenge in the 3D printing industry has been replicating an object’s internal texture.

In their recent study “Digital Wood: 3D Internal Color Texture Mapping” the research team describes how a system of “color and voxel mapping “led to the production of a 3D printed closely resembling the texture of olive wood, including a cut-through section.
