On the island of Djurgården, close to Stockholm’s city center and Skeppsholmen Island (location of Rafael Moneo’s Moderna Museet and Arkitekturmuseet), Liljevalchs Konsthall has a new wing. A work of the Swedish practice of Gert Wingårdh, the rectangular concrete block presents a sculptural roof perforated by 166 skylights that brighten up the interior generously. The annex provides the institution with extra space for exhibitions, a second entrance, a store, and a café. The facade was designed in collaboration with the glass artist Ingegerd Råman. The composition formed by 6,860 bottle ends gives rhythm to the outer skin.
