ONSIL is a new space that blends a library and hotel, where guests can relax with books and reflect on themselves. The name 'ONSIL,' which means 'green house' in Korean, reflects the idea of the hotel being a warm space where people can grow. The symbol is inspired by the image of a warm sun and the side view of a book. To emphasize the hotel's connection to books, square brackets — often found in dictionaries — are incorporated into the wordmark.
