The restoration of Leiden’s museum of art, applied art and history involves knitting together a group of buildings from different periods, the oldest designed in 1641. The architect has also cleared and glazed the central courtyard, creating an orientation hub, and has added an extension. With the mix of styles, each with its own aesthetic, what could be more appropriate than some classic ironmongery? The architect has used izé’s MIESL01 lever handles which, with their timeless modernity, sit well within this considered and subtle project. Designed originally for Mies’ unbuilt Mansion House Square tower in London and never used, they add an additional layer of historic interest while offering an elegant and wholly appropriate functionality.
