This booklet presents architecture in a manner rarely seen today: sketches drawn by hand. A sketch captures architecture through the eyes of its author, and this personal aspect is what makes it so valuable. Here, the sketch also serves as a tool to illustrate the fundamental concepts of designs by Slovene architect Jože Plečnik (1872–1957), who gave the city of Ljubljana its modern identity through his iconic buildings and urban plans, which reflect a timeless aesthetic and qualities. Plečnik holds a special place among his Slovenian peers, and the complex project of nominating his architectural work for inscription on the UNESCO World Heritage List is this book’s starting point.
