Unless you’re very offline, design-wise, you probably know about Prague-based architecture historian and curator — as well as frequent Sight Unseen contributor! — Adam Štěch. On his well-loved Instagram account, @okolo_architecture, he’s been assiduously and beautifully cataloging 20th-century architecture and interior design details for years. His photographic efforts aren’t simply representative, they’re revelatory, and they’re currently on view as part of Salone in his Elements exhibition at Dropcity, a new center for architecture and design in Milan. By focusing on the parts — the lighting, seating, tables, railings, doors, handles, windows, floors, and more — Štěch’s 3,000 images give us a new sense of the whole: not only the larger project of how a particular building was put together in a cohesive way, but a comprehensive view of how architecture and design developed and moved throughout the last century, charting the differences and similarities of Modernist buildings over time and through place.
